Notes:
1. There are no LVTTL capable direct inputs available on A2F060 devices.
2. These pins are shared between direct analog inputs to the ADCs and voltage/current/temperature monitors.
3. 16 MSS I/Os are multiplexed and can be used as FPGA I/Os, if not needed for MSS. These I/Os support Schmitt triggers and
support only LVTTL and LVCMOS (1.5 / 1.8 / 2.5, 3.3 V) standards.
4. 9 MSS I/Os are primarily for 10/100 Ethernet MAC and are also multiplexed and can be used as FPGA I/Os if Ethernet MAC is
not used in a design. These I/Os support Schmitt triggers and support only LVTTL and LVCMOS (1.5 / 1.8 / 2.5, 3.3 V
standards.
5. 10/100 Ethernet MAC is not available on A2F060.
6. EMC is not available on the A2F500 PQ208 and A2F060 TQ144 package.

SmartFusion Customizable System-on-Chip (cSoC)
1 – SmartFusion Family Overview
Introduction
The SmartFusion® family of cSoCs builds on the technology first introduced with the Fusion mixed signal
FPGAs. SmartFusion cSoCs are made possible by integrating FPGA technology with programmable
high-performance analog and hardened ARM Cortex-M3 microcontroller blocks on a flash semiconductor
process. The SmartFusion cSoC takes its name from the fact that these three discrete technologies are
integrated on a single chip, enabling the lowest cost of ownership and smallest footprint solution to you.
General Description
Microcontroller Subsystem (MSS)
The MSS is composed of a 100 MHz Cortex-M3 processor and integrated peripherals, which are
interconnected via a multi-layer AHB bus matrix (ABM). This matrix allows the Cortex-M3 processor,
FPGA fabric master, Ethernet media access controller (MAC), when available, and peripheral DMA
(PDMA) controller to act as masters to the integrated peripherals, FPGA fabric, embedded nonvolatile
memory (eNVM), embedded synchronous RAM (eSRAM), external memory controller (EMC), and
analog compute engine (ACE) blocks.
SmartFusion cSoCs of different densities offer various sets of integrated peripherals. Available
peripherals include SPI, I2C, and UART serial ports, embedded FlashROM (EFROM), 10/100 Ethernet
MAC, timers, phase-locked loops (PLLs), oscillators, real-time counters (RTC), and peripheral DMA
controller (PDMA).
Programmable Analog
Analog Front-End (AFE)
SmartFusion cSoCs offer an enhanced analog front-end compared to Fusion devices. The successive
approximation register analog-to-digital converters (SAR ADC) are similar to those found on Fusion
devices. SmartFusion cSoC also adds first order sigma-delta digital-to-analog converters (SDD DAC).
SmartFusion cSoCs can handle multiple analog signals simultaneously with its signal conditioning blocks
(SCBs). SCBs are made of a combination of active bipolar prescalers (ABPS), comparators, current
monitors and temperature monitors. ABPS modules allow larger bipolar voltages to be fed to the ADC.
Current monitors take the voltage across an external sense resistor and convert it to a voltage suitable
for the ADC input range. Similarly, the temperature monitor reads the current through an external PNjunction (diode or transistor) and converts it internally for the ADC. The SCB also includes comparators
to monitor fast signal thresholds without using the ADC. The output of the comparators can be fed to the
analog compute engine or the ADC.
Analog Compute Engine (ACE)
The mixed signal blocks found in SmartFusion cSoCs are controlled and connected to the rest of the
system via a dedicated processor called the analog compute engine (ACE). The role of the ACE is to
offload control of the analog blocks from the Cortex-M3, thus offering faster throughput or better power
consumption compared to a system where the main processor is in charge of monitoring the analog
resources. The ACE is built to handle sampling, sequencing, and post-processing of the ADCs, DACs,
and SCBs.

SmartFusion Family Overview
ProASIC3 FPGA Fabric
The SmartFusion cSoC family, based on the proven, low power, firm-error immune ProASIC®3 flash
FPGA architecture, benefits from the advantages only flash-based devices offer:
Reduced Cost of Ownership
Advantages to the designer extend beyond low unit cost, high performance, and ease of use. Flashbased SmartFusion cSoCs are Instant On and do not need to be loaded from an external boot PROM at
each power-up. On-board security mechanisms prevent access to the programming information and
enable secure remote updates of the FPGA logic. Designers can perform secure remote in-system
programming (ISP) to support future design iterations and critical field upgrades, with confidence that
valuable IP cannot be compromised or copied. Secure ISP can be performed using the industry standard
AES algorithm with MAC data authentication on the device.
Low Power
Flash-based SmartFusion cSoCs exhibit power characteristics similar to those of an ASIC, making them
an ideal choice for power-sensitive applications. With SmartFusion cSoCs, there is no power-on current
and no high current transition, both of which are common with SRAM-based FPGAs.
SmartFusion cSoCs also have low dynamic power consumption and support very low power timekeeping mode, offering further power savings.
Security
As the nonvolatile, flash-based SmartFusion cSoC family requires no boot PROM, there is no vulnerable
external bitstream. SmartFusion cSoCs incorporate FlashLock®, which provides a unique combination of
reprogrammability and design security without external overhead, advantages that only a device with
nonvolatile flash programming can offer.
SmartFusion cSoCs utilize a 128-bit flash-based key lock and a separate AES key to provide security for
programmed IP and configuration data. The FlashROM data in Fusion devices can also be encrypted
prior to loading. Additionally, the flash memory blocks can be programmed during runtime using the AES128 block cipher encryption standard (FIPS Publication 192).
SmartFusion cSoCs with AES-based security are designed to provide protection for remote field updates
over public networks, such as the Internet, and help to ensure that valuable IP remains out of the hands
of system overbuilders, system cloners, and IP thieves. As an additional security measure, the FPGA
configuration data of a programmed Fusion device cannot be read back, although secure design
verification is possible. During design, the user controls and defines both internal and external access to
the flash memory blocks.
Security, built into the FPGA fabric, is an inherent component of the SmartFusion cSoC family. The flash
cells are located beneath seven metal layers, and many device design and layout techniques have been
used to make invasive attacks extremely difficult. SmartFusion cSoCs, with FlashLock and AES security,
are unique in being highly resistant to both invasive and noninvasive attacks. Your valuable IP is
protected with industry standard security measures, making remote ISP feasible. A SmartFusion cSoC
provides the highest security available for programmable logic designs.
Single Chip
Flash-based FPGAs store their configuration information in on-chip flash cells. Once programmed, the
configuration data is an inherent part of the FPGA structure, and no external configuration data needs to
be loaded at system power-up (unlike SRAM-based FPGAs). Therefore, flash-based SmartFusion
cSoCs do not require system configuration components such as electrically erasable programmable
read-only memories (EEPROMs) or microcontrollers to load device configuration data during power-up.
This reduces bill-of-materials costs and PCB area, and increases system security and reliability.
Instant On
Flash-based SmartFusion cSoCs are Instant On. Instant On SmartFusion cSoCs greatly simplify total
system design and reduce total system cost by eliminating the need for complex programmable logic
devices (CPLDs). SmartFusion Instant On clocking (PLLs) replace off-chip clocking resources. In
addition, glitches and brownouts in system power will not corrupt the SmartFusion flash configuration.
Unlike SRAM-based FPGAs, the device will not have to be reloaded when system power is restored.

SmartFusion Customizable System-on-Chip (cSoC)
This enables reduction or complete removal of expensive voltage monitor and brownout detection
devices from the PCB design. Flash-based SmartFusion cSoCs simplify total system design and reduce
cost and design risk, while increasing system reliability.
Immunity to Firm Errors
Firm errors occur most commonly when high-energy neutrons, generated in the atmosphere, strike a
configuration cell of an SRAM FPGA. The energy of the collision can change the state of the
configuration cell and thus change the logic, routing, or I/O configuration behavior in an unpredictable
way.
Another source of radiation-induced firm errors is alpha particles. For alpha radiation to cause a soft or
firm error, its source must be in very close proximity to the affected circuit. The alpha source must be in
the package molding compound or in the die itself. While low-alpha molding compounds are being used
increasingly, this helps reduce but does not entirely eliminate alpha-induced firm errors.
Firm errors are impossible to prevent in SRAM FPGAs. The consequence of this type of error can be a
complete system failure. Firm errors do not occur in SmartFusion cSoCs. Once it is programmed, the
flash cell configuration element of SmartFusion cSoCs cannot be altered by high energy neutrons and is
therefore immune to errors from them. Recoverable (or soft) errors occur in the user data SRAMs of all
FPGA devices. These can easily be mitigated by using error detection and correction (EDAC) circuitry
built into the FPGA fabric.
Specifying I/O States During Programming
You can modify the I/O states during programming in FlashPro. In FlashPro, this feature is supported for
PDB files generated from Designer v8.5 or greater. See the FlashPro User’s Guide for more information.
Note: PDB files generated from Designer v8.1 to Designer v8.4 (including all service packs) have
limited display of Pin Numbers only.
The I/Os are controlled by the JTAG Boundary Scan register during programming, except for the analog
pins (AC, AT and AV). The Boundary Scan register of the AG pin can be used to enable/disable the gate
driver in software v9.0.
1. Load a PDB from the FlashPro GUI. You must have a PDB loaded to modify the I/O states during
programming.
2. From the FlashPro GUI, click PDB Configuration. A FlashPoint – Programming File Generator
window appears.
3. Click the Specify I/O States During Programming button to display the Specify I/O States During
Programming dialog box.
4. Sort the pins as desired by clicking any of the column headers to sort the entries by that header.
Select the I/Os you wish to modify (Figure 1-1 on page 1-4).
5. Set the I/O Output State. You can set Basic I/O settings if you want to use the default I/O settings
for your pins, or use Custom I/O settings to customize the settings for each pin. Basic I/O state
settings:
1 – I/O is set to drive out logic High
0 – I/O is set to drive out logic Low
Last Known State – I/O is set to the last value that was driven out prior to entering the
programming mode, and then held at that value during programming
Z -Tri-State: I/O is tristated

maximum overshoot/undershoot has to be reduced by 0.15 V.
3. This table does not provide PCI overshoot/undershoot limits.
Power Supply Sequencing Requirement
SmartFusion cSoCs have an on-chip 1.5 V regulator, but usage of an external 1.5 V supply is also
allowed while the on-chip regulator is disabled. In that case, the 3.3 V supplies (VCC33A, etc.) should be
powered before 1.5 V (VCC, etc.) supplies. The 1.5 V supplies should be enabled only after 3.3 V
supplies reach a value higher than 2.7 V.
I/O Power-Up and Supply Voltage Thresholds for Power-On Reset
(Commercial and Industrial)
Sophisticated power-up management circuitry is designed into every SmartFusion cSoC. These circuits
ensure easy transition from the powered-off state to the powered-up state of the device. In addition, the
I/O will be in a known state through the power-up sequence. The basic principle is shown in Figure 2-1
on page 2-6.
There are five regions to consider during power-up.
SmartFusion I/Os are activated only if ALL of the following three conditions are met:
1. VCC and VCCxxxxIOBx are above the minimum specified trip points (Figure 2-1 on page 2-6).
2. VCCxxxxIOBx > VCC – 0.75 V (typical)
3. Chip is in the SoC Mode.

Ramping up: 0.6 V < trip_point_up < 1.1 V
Ramping down: 0.5 V < trip_point_down < 1 V
VCC and VCCxxxxIOBx ramp-up trip points are about 100 mV higher than ramp-down trip points. This
specifically built-in hysteresis prevents undesirable power-up oscillations and current surges. Note the
following:
•
By default, during programming I/Os become tristated and weakly pulled up to VCCxxxxIOBx.
You can modify the I/O states during programming in FlashPro. For more details, refer to
"Specifying I/O States During Programming" on page 1-3.
•
JTAG supply, PLL power supplies, and charge pump VPUMP supply have no influence on I/O
behavior.
PLL Behavior at Brownout Condition
The Microsemi SoC Products Group recommends using monotonic power supplies or voltage regulators
to ensure proper power-up behavior. Power ramp-up should be monotonic at least until VCC and
VCCPLLx exceed brownout activation levels. The VCC activation level is specified as 1.1 V worst-case
(see Figure 2-1 on page 2-6 for more details).
When PLL power supply voltage and/or VCC levels drop below the VCC brownout levels (0.75 V ± 0.25
V), the PLL output lock signal goes low and/or the output clock is lost. Refer to the "Power-Up/-Down
Behavior of Low Power Flash Devices" chapter of the ProASIC3 FPGA Fabric User’s Guide for
information on clock and lock recovery.

Thermal Characteristics
Introduction
The temperature variable in the SoC Products Group Designer software refers to the junction
temperature, not the ambient, case, or board temperatures. This is an important distinction because
dynamic and static power consumption will cause the chip's junction temperature to be higher than the
ambient, case, or board temperatures. EQ 1 through EQ 3 give the relationship between thermal
resistance, temperature gradient, and power.

Junction-to-ambient thermal resistance (θJA) is determined under standard conditions specified by
JEDEC (JESD-51), but it has little relevance in actual performance of the product. It should be used with
caution but is useful for comparing the thermal performance of one package to another.
A sample calculation showing the maximum power dissipation allowed for the A2F200-FG484 package
under forced convection of 1.0 m/s and 75°C ambient temperature is as follows:
T J(MAX) – T A(MAX)
Maximum Power Allowed = -------------------------------------------θ JA
EQ 4
where
θJA
= 19.00°C/W (taken from Table 2-6 on page 2-7).
TA
= 75.00°C
– 75.00°C = 1.3 W
Maximum Power Allowed = 100.00°C
---------------------------------------------------19.00°C/W
EQ 5
The power consumption of a device can be calculated using the Microsemi SoC Products Group power
calculator. The device's power consumption must be lower than the calculated maximum power
dissipation by the package. If the power consumption is higher than the device's maximum allowable
power dissipation, a heat sink can be attached on top of the case, or the airflow inside the system must
be increased.
Theta-JB
Junction-to-board thermal resistance (θJB) measures the ability of the package to dissipate heat from the
surface of the chip to the PCB. As defined by the JEDEC (JESD-51) standard, the thermal resistance
from junction to board uses an isothermal ring cold plate zone concept. The ring cold plate is simply a
means to generate an isothermal boundary condition at the perimeter. The cold plate is mounted on a
JEDEC standard board with a minimum distance of 5.0 mm away from the package edge.
Theta-JC
Junction-to-case thermal resistance (θJC) measures the ability of a device to dissipate heat from the
surface of the chip to the top or bottom surface of the package. It is applicable for packages used with
external heat sinks. Constant temperature is applied to the surface in consideration and acts as a
boundary condition. This only applies to situations where all or nearly all of the heat is dissipated through
the surface in consideration.
Calculation for Heat Sink
For example, in a design implemented in an A2F200-FG484 package with 2.5 m/s airflow, the power
consumption value using the power calculator is 3.00 W. The user-dependent Ta and Tj are given as
follows:
TJ
=
100.00°C
TA =
70.00°C
From the datasheet:
2- 8
θJA
=
17.00°C/W
θJC
=
8.28°C/W
R ev isio n 1 2
SmartFusion Customizable System-on-Chip (cSoC)
TJ – TA
– 70°C- = 1.76 W
P = ------------------ = 100°C
----------------------------------θ JA
17.00 W
EQ 6
The 1.76 W power is less than the required 3.00 W. The design therefore requires a heat sink, or the
airflow where the device is mounted should be increased. The design's total junction-to-air thermal
resistance requirement can be estimated by EQ 7:
TJ – TA
100°C – 70°C- = 10.00°C/W
- = ----------------------------------θ JA(total) = -----------------P
3.00 W
EQ 7
Determining the heat sink's thermal performance proceeds as follows:
θ JA(TOTAL) = θ JC + θ CS + θ SA
EQ 8
where
θJA
θSA
=
0.37°C/W
=
Thermal resistance of the interface material between
the case and the heat sink, usually provided by the
thermal interface manufacturer
=
Thermal resistance of the heat sink in °C/W
θ SA = θ JA(TOTAL) – θ JC – θ CS
EQ 9
θ SA = 13.33°C/W – 8.28°C/W – 0.37°C/W = 5.01°C/W
A heat sink with a thermal resistance of 5.01°C/W or better should be used. Thermal resistance of heat
sinks is a function of airflow. The heat sink performance can be significantly improved with increased
airflow.
Carefully estimating thermal resistance is important in the long-term reliability of an FPGA. Design
engineers should always correlate the power consumption of the device with the maximum allowable
power dissipation of the package selected for that device.
Note: The junction-to-air and junction-to-board thermal resistances are based on JEDEC standard
(JESD-51) and assumptions made in building the model. It may not be realized in actual
application and therefore should be used with a degree of caution. Junction-to-case thermal
resistance assumes that all power is dissipated through the case.

Toggle Rate Definition
A toggle rate defines the frequency of a net or logic element relative to a clock. It is a percentage. If the
toggle rate of a net is 100%, this means that the net switches at half the clock frequency. Below are some
examples:
•
The average toggle rate of a shift register is 100%, as all flip-flop outputs toggle at half of the clock
frequency.
•
The average toggle rate of an 8-bit counter is 25%:

Bit 0 (LSB) = 100%
–
Bit 1 = 50%
–
Bit 2 = 25%
–
…
–
Bit 7 (MSB) = 0.78125%
–
Average toggle rate = (100% + 50% + 25% + 12.5% + . . . 0.78125%) / 8.
Enable Rate Definition
Output enable rate is the average percentage of time during which tristate outputs are enabled. When
non-tristate output buffers are used, the enable rate should be 100%.

The length of time an I/O can withstand IOSH/IOSL events depends on the junction temperature. The
reliability data below is based on a 3.3 V, 12 mA I/O setting, which is the worst case for this type of
analysis.
For example, at 100°C, the short current condition would have to be sustained for more than 2200
operation hours to cause a reliability concern. The I/O design does not contain any short circuit
protection, but such protection would only be needed in extremely prolonged stress conditions.

Note: *The maximum input rise/fall time is related to the noise induced into the input buffer trace. If the
noise is low, then the rise time and fall time of input buffers can be increased beyond the
maximum value. The longer the rise/fall times, the more susceptible the input signal is to the board
noise. Microsemi SoC Products Group recommends signal integrity evaluation/characterization of
the system to ensure that there is no excessive noise coupling into input signals.

SmartFusion DC and Switching Characteristics
Differential I/O Characteristics
Physical Implementation
Configuration of the I/O modules as a differential pair is handled by SoC Products Group Designer
software when the user instantiates a differential I/O macro in the design.
Differential I/Os can also be used in conjunction with the embedded Input Register (InReg), Output
Register (OutReg), Enable Register (EnReg), and Double Data Rate (DDR). However, there is no
support for bidirectional I/Os or tristates with the LVPECL standards.
LVDS
Low-Voltage Differential Signaling (ANSI/TIA/EIA-644) is a high-speed, differential I/O standard. It
requires that one data bit be carried through two signal lines, so two pins are needed. It also requires
external resistor termination.
The full implementation of the LVDS transmitter and receiver is shown in an example in Figure 2-11. The
building blocks of the LVDS transmitter-receiver are one transmitter macro, one receiver macro, three
board resistors at the transmitter end, and one resistor at the receiver end. The values for the three driver
resistors are different from those used in the LVPECL implementation because the output standard
specifications are different.
Along with LVDS I/O, SmartFusion cSoCs also support bus LVDS structure and multipoint LVDS
(M-LVDS) configuration (up to 40 nodes).

SmartFusion DC and Switching Characteristics
B-LVDS/M-LVDS
Bus LVDS (B-LVDS) and Multipoint LVDS (M-LVDS) specifications extend the existing LVDS standard to
high-performance multipoint bus applications. Multidrop and multipoint bus configurations may contain
any combination of drivers, receivers, and transceivers. SoC Products Group LVDS drivers provide the
higher drive current required by B-LVDS and M-LVDS to accommodate the loading. The drivers require
series terminations for better signal quality and to control voltage swing. Termination is also required at
both ends of the bus since the driver can be located anywhere on the bus. These configurations can be
implemented using the TRIBUF_LVDS and BIBUF_LVDS macros along with appropriate terminations.
Multipoint designs using SoC Products Group LVDS macros can achieve up to 200 MHz with a maximum
of 20 loads. A sample application is given in Figure 2-12. The input and output buffer delays are available
in the LVDS section in Table 2-65.
Example: For a bus consisting of 20 equidistant loads, the following terminations provide the required
differential voltage, in worst-case commercial operating conditions, at the farthest receiver: RS = 60 Ω
and RT = 70 Ω, given Z0 = 50 Ω (2") and Zstub = 50 Ω (~1.5").

LVPECL
Low-Voltage Positive Emitter-Coupled Logic (LVPECL) is another differential I/O standard. It requires
that one data bit be carried through two signal lines. Like LVDS, two pins are needed. It also requires
external resistor termination.
The full implementation of the LVDS transmitter and receiver is shown in an example in Figure 2-13. The
building blocks of the LVPECL transmitter-receiver are one transmitter macro, one receiver macro, three
board resistors at the transmitter end, and one resistor at the receiver end. The values for the three driver
resistors are different from those used in the LVDS implementation because the output standard
specifications are different.

Global Resource Characteristics
A2F200 Clock Tree Topology
Clock delays are device-specific. Figure 2-27 is an example of a global tree used for clock routing. The
global tree presented in Figure 2-27 is driven by a CCC located on the west side of the A2F200 device. It
is used to drive all D-flip-flops in the device.

Figure 2-27 • Example of Global Tree Use in an A2F200 Device for Clock Routing
Global Tree Timing Characteristics
Global clock delays include the central rib delay, the spine delay, and the row delay. Delays do not
include I/O input buffer clock delays, as these are I/O standard–dependent, and the clock may be driven
and conditioned internally by the CCC module. For more details on clock conditioning capabilities, refer
to the "Clock Conditioning Circuits" section on page 2-63. Table 2-80 through Table 2-82 on page 2-61
present minimum and maximum global clock delays for the SmartFusion cSoCs. Minimum and maximum
delays are measured with minimum and maximum loading.

Notes:
1. One of the CCC outputs (GLA0) is used as an MSS clock and is limited to 100 MHz (maximum) by software. Details
regarding CCC/PLL are in the "PLLs, Clock Conditioning Circuitry, and On-Chip Crystal Oscillators" chapter of the
SmartFusion Microcontroller Subsystem User's Guide.
2. This delay is a function of voltage and temperature. See Table 2-7 on page 2-9 for deratings.
3. TJ = 25°C, VCC = 1.5 V
4. When the CCC/PLL core is generated by Microsemi core generator software, not all delay values of the specified delay
increments are available. Refer to the Libero SoC Online Help associated with the core for more information.
5. Tracking jitter is defined as the variation in clock edge position of PLL outputs with reference to the PLL input clock edge.
Tracking jitter does not measure the variation in PLL output period, which is covered by the period jitter parameter.
6. Measurement done with LVTTL 3.3 V 12 mA I/O drive strength and High slew rate. VCC/VCCPLL = 1.425 V,
VCCI = 3.3V, 20 pF output load. All I/Os are placed outside of the PLL bank.
7. SSOs are outputs that are synchronous to a single clock domain and have their clock-to-out within ± 200 ps of each other.
8. VCO output jitter is calculated as a percentage of the VCO frequency. The jitter (in ps) can be calculated by multiplying
the VCO period by the % jitter. The VCO jitter (in ps) applies to CCC_OUT regardless of the output divider settings. For
example, if the jitter on VCO is 300 ps, the jitter on CCC_OUT is also 300 ps.

Analog Bipolar Prescaler (ABPS)
With the ABPS set to its high range setting (GDEC = 00), a hypothetical input voltage in the range –15.36
V to +15.36 V is scaled and offset by the ABPS input amplifier to match the ADC full range of 0 V to 2.56
V using a nominal gain of –0.08333 V/V. However, due to reliability considerations, the voltage applied to
the ABPS input should never be outside the range of –11.5 V to +14.4 V, restricting the usable ADC input
voltage to 2.238 V to 0.080 V and the corresponding 12-bit output codes to the range of 3581 to 128
(decimal), respectively.
Unless otherwise noted, ABPS performance is specified at 25°C with nominal power supply voltages,
with the output measured using the internal voltage reference with the internal ADC in 12-bit mode and
100 KHz sampling frequency, after trimming and digital compensation; and applies to all ranges.

3 – SmartFusion Development Tools
Designing with SmartFusion cSoCs involves three different types of design: FPGA design, embedded
design and analog design. These roles can be filled by three different designers, two designers or even a
single designer, depending on company structure and project complexity.
Types of Design Tools
Microsemi has developed design tools and flows to meet the needs of these three types of designers so
they can work together smoothly on a single project (Figure 3-1).

SmartFusion Development Tools
Embedded Design
Microsemi offers FREE SoftConsole Eclipse based IDE, which includes the GNU C/C++ compiler and
GDB debugger. Microsemi also offers evaluation versions of software from Keil and IAR, with full
versions available from respective suppliers.
Analog Design
The MSS configurator provides graphical configuration for current, voltage and temperature monitors,
sample sequencing setup and post-processing configuration, as well as DAC output.
The MSS configurator creates a bridge between the FPGA fabric and embedded designers so device
configuration can be easily shared between multiple developers.
The MSS configurator includes the following:
•
A simple configurator for the embedded designer to control the MSS peripherals and I/Os
•
A method to import and view a hardware configuration from the FPGA flow into the embedded
flow containing the memory map
•
Automatic generation of drivers for any peripherals or soft IP used in the system configuration
•
Comprehensive analog configuration for the programmable analog components
•
Creation of a standard MSS block to be used in SmartDesign for connection of FPGA fabric
designs and IP

SmartFusion Ecosystem
The Microsemi SoC Products Group has a long history of supplying comprehensive FPGA development
tools and recognizes the benefit of partnering with industry leaders to deliver the optimum usability and
productivity to customers. Taking the same approach with processor development, Microsemi has
partnered with key industry leaders in the microcontroller space to provide the robust SmartFusion
ecosystem.
Microsemi is partnering with Keil and IAR to provide Software IDE support to SmartFusion system
designers. The result is a robust solution that can be easily adopted by developers who are already doing
embedded design. The learning path is straightforward for FPGA designers.
Support for the SoC Products Group device and ecosystem resources is represented in Figure 3-3.

SmartFusion Ecosystem
Figure 3-3 shows the SmartFusion stack with examples of drivers, RTOS, and middleware from
Microsemi and partners. By leveraging the SmartFusion stack, designers can decide at which level to
add their own customization to their design, thus speeding time to market and reducing overhead in the
design.
ARM
Because an ARM processor was chosen for SmartFusion cSoCs, Microsemi's customers can benefit
from the extensive ARM ecosystem. By building on Microsemi supplied hardware abstraction layer (HAL)
and drivers, third party vendors can easily port RTOS and middleware for the SmartFusion cSoC.

SmartFusion Customizable System-on-Chip (cSoC)
4 – SmartFusion Programming
SmartFusion cSoCs have three separate flash areas that can be programmed:
1. The FPGA fabric
2. The embedded nonvolatile memories (eNVMs)
3. The embedded flash ROM (eFROM)
There are essentially three methodologies for programming these areas:
1. In-system programming (ISP)
2. In-application programming (IAP)
a. A2F060 and A2F500: The FPGA fabric, eNVM, and eFROM
b. A2F200: Only the FPGA fabric and the eNVM
3. Pre-programming (non-ISP)
Programming, whether ISP or IAP methodologies are employed, can be done in two ways:
1. Securely using the on chip AES decryption logic
2. In plain text
In-System Programming
In-System Programming is performed with the aid of external JTAG programming hardware. Table 4-1
describes the JTAG programming hardware that will program a SmartFusion cSoC and Table 4-2 defines
the JTAG pins that provide the interface for the programming hardware.

SmartFusion Programming
The JTAGSEL pin selects the FPGA TAP controller or the Cortex-M3 debug logic. When JTAGSEL is
asserted, the FPGA TAP controller is selected and the TRSTB input into the Cortex-M3 is held in a reset
state (logic 0), as depicted in Figure 4-1. Users should tie the JTAGSEL pin high externally.
Microsemi’s free Eclipse-based IDE, SoftConsole, has the ability to control the JTAGSEL pin directly with
the FlashPro4 programmer. Manual jumpers are provided on the evaluation and development kits to
allow manual selection of this function for the J-Link and ULINK debuggers.
Note: Standard ARM JTAG connectors do not have access to the JTAGSEL pin. SoftConsole
automatically selects the appropriate TAP controller using the CTXSELECT JTAG command.
When using SoftConsole, the state of JTAGSEL is a "don't care."

In-Application Programming
In-application programming refers to the ability to reprogram the various flash areas under direct
supervision of the Cortex-M3.
Reprogramming the FPGA Fabric Using the Cortex-M3
In this mode, the Cortex-M3 is executing the programming algorithm on-chip. The IAP driver can be
incorporated into the design project and executed from eNVM or eSRAM. The SoC Products Group
provides working example projects for SoftConsole, IAR, and Keil development environments. These can
be downloaded via the SoC Products Group Firmware Catalog. The new bitstream to be programmed
into the FPGA can reside on the user’s printed circuit board (PCB) in a separate SPI flash memory.
Alternately, the user can modify the existing projects supplied by the SoC Products Group and, via
custom handshaking software, throttle the download of the new image and program the FPGA a piece at
a time in real time. A cost-effective and reliable approach would be to store the bitstream in an external
SPI flash. Another option is storing a redundant bitstream image in an external SPI flash and loading the
newest version into the FPGA only when receiving an IAP command. Since the FPGA I/Os are tristated
or held at predefined or last known state during FPGA programming, the user must use MSS I/Os to
interface to external memories. Since there are two SPI controllers in the MSS, the user can dedicate
one to an SPI flash and the other to the particulars of an application. The amount of flash memory
required to program the FPGA always exceeds the size of the eNVM block that is on-chip. The external
memory controller (EMC) cannot be used as an interface to a memory device for storage of a bitstream
because its I/O pads are FPGA I/Os; hence they are tristated when the FPGA is in a programming state.
The MSS resets itself after IAP of the FPGA fabric. This reset is internally asserted on MSS_RESETN by
the power supply monitor (PSM) and reset controller of the MSS.

R ev isio n 1 2
SmartFusion Customizable System-on-Chip (cSoC)
Re-Programming the eNVM Blocks Using the Cortex-M3
In this mode the Cortex-M3 is executing the eNVM programming algorithm from eSRAM. Since individual
pages (132 bytes) of the eNVM can be write-protected, the programming algorithm software can be
protected from inadvertent erasure. When reprogramming the eNVM, both MSS I/Os and FPGA I/Os are
available as interfaces for sourcing the new eNVM image. The SoC Products Group provides working
example projects for SoftConsole, IAR, and Keil development environments. These can be downloaded
via the SoC Products Group Firmware Catalog.
Alternately, the eNVM can be reprogrammed by the Cortex-M3 via the IAP driver. This is necessary when
using an encrypted image.
Secure Programming
For background, refer to the "Security in Low Power Flash Devices" chapter of the Fusion FPGA Fabric
User’s Guide on the SoC Products Group website. SmartFusion ISP behaves identically to Fusion ISP.
IAP of SmartFusion cSoCs is accomplished by using the IAP driver. Only the FPGA fabric and the eNVM
can be reprogrammed with the protection of security measures by using the IAP driver.
Typical Programming and Erase Times
Table 4-3 documents the typical programming and erase times for two components of SmartFusion
cSoCs, FPGA fabric and eNVM, using the SoC Products Group’s FlashPro hardware and software.
These times will be different for other ISP and IAP methods. The Program action in FlashPro software
includes erase, program, and verify to complete.
The typical programming (including erase) time per page of the eNVM is 8 ms.

VJTAG
Supply
Description
Digital supply to the JTAG controller
SmartFusion cSoCs have a separate bank for the dedicated JTAG pins. The JTAG pins
can be run at any voltage from 1.5 V to 3.3 V (nominal). Isolating the JTAG power
supply in a separate I/O bank gives greater flexibility in supply selection and simplifies
power supply and PCB design. If the JTAG interface is neither used nor planned to be
used, the VJTAG pin together with the TRSTB pin could be tied to GND. Note that VCC
is required to be powered for JTAG operation; VJTAG alone is insufficient. If a
SmartFusion cSoC is in a JTAG chain of interconnected boards and it is desired to
power down the board containing the device, this can be done provided both VJTAG
and VCC to the device remain powered; otherwise, JTAG signals will not be able to
transition the device, even in bypass mode. See "JTAG Pins" section on page 5-10.
VPP
Supply
Digital programming circuitry supply
SmartFusion cSoCs support single-voltage in-system programming (ISP) of the
configuration flash, embedded FlashROM (eFROM), and embedded nonvolatile
memory (eNVM).
For programming, VPP should be in the 3.3 V ± 5% range. During normal device
operation, VPP can be left floating or can be tied to any voltage between 0 V and 3.6 V.
When the VPP pin is tied to ground, it shuts off the charge pump circuitry, resulting in no
sources of oscillation from the charge pump circuitry. For proper programming, 0.01μF,
and 0.1μF to 1μF capacitors, (both rated at 16 V) are to be connected in parallel across
VPP and GND, and positioned as close to the FPGA pins as possible.

Description
Analog reference voltage for first ADC.
The SmartFusion cSoC can be configured to generate a 2.56 V internal reference
that can be used by the ADC. While using the internal reference, the reference
voltage is output on the VAREFOUT pin for use as a system reference. If a
different reference voltage is required, it can be supplied by an external source
and applied to this pin. The valid range of values that can be supplied to the ADC
is 1.0 V to 3.3 V. When VAREF0 is internally generated, a bypass capacitor must
be connected from this pin to ground. The value of the bypass capacitor should be
between 3.3 µF and 22 µF, which is based on the needs of the individual designs.
The choice of the capacitor value has an impact on the settling time it takes the
VAREF0 signal to reach the required specification of 2.56 V to initiate valid
conversions by the ADC. If the lower capacitor value is chosen, the settling time
required for VAREF0 to achieve 2.56 V will be shorter than when selecting the
larger capacitor value. The above range of capacitor values supports the accuracy
specification of the ADC, which is detailed in the datasheet. Designers choosing
the smaller capacitor value will not obtain as much margin in the accuracy as that
achieved with a larger capacitor value. See the Analog-to-Digital Converter (ADC)
section in the SmartFusion Programmable Analog User’s Guide for more
information. The SoC Products Group recommends customers use 10 µF as the
value of the bypass capacitor. Designers choosing to use an external VAREF0
need to ensure that a stable and clean VAREF0 source is supplied to the VAREF0
pin before initiating conversions by the ADC. To use the internal voltage reference,
the VAREFOUT pin must be connected to the appropriate ADC VAREFx input on
the PCB. For example, VAREFOUT can be connected to VAREF0 only, if ADC0
alone is used. VAREFOUT can be connected to VAREF1 only, if ADC1 alone is
used. VAREFOUT can be connected to VAREF2 only, if ADC2 alone is used.
VAREFOUT can be connected to VAREF0, VAREF1 and VAREF2 together, if
ADC0, ADC1, and ADC2 all are used.

Pin Descriptions
Global I/O Naming Conventions
Gmn (Gxxx) refers to Global I/Os. These Global I/Os are used to connect the input to global networks.
Global networks have high fanout and low skew. The naming convention for Global I/Os is as follows:
G = Global
m = Global pin location associated with each CCC on the device:
–
A (northwest corner)
–
B (northeast corner)
–
C (east middle)
–
D (southeast corner)
–
E (southwest corner)
–
F (west middle)
n = Global input MUX and pin number of the associated Global location m—A0, A1, A2, B0, B1, B2,
C0, C1, or C2.
Global (GL) I/Os have access to certain clock conditioning circuitry (and the PLL) and/or have direct
access to the global network (spines). Additionally, the global I/Os can be used as regular I/Os, since
they have identical capabilities.
Unused GL pins are configured as inputs with pull-up resistors. See more detailed descriptions of global
I/O connectivity in the clocking resources chapter of the SmartFusion FPGA Fabric User’s Guide and the
clock conditioning circuitry chapter of the SmartFusion Microcontroller Subsystem User’s Guide.
All inputs other than GC/GF are direct inputs into the quadrant clocks. The inputs to the global network
are multiplexed, and only one input can be used as a global input. For example, if GAA0 is used as a
quadrant global input, GAA1 and GAA2 are no longer available for input to the quadrant globals. All
inputs other than GC/GF are direct inputs into the chip-level globals, and the rest are connected to the
quadrant globals. For more details, refer to the Global Input Selections section of the SmartFusion Fabric
User Guide.

Description
Microcontroller Subsystem (MSS) General Purpose I/O (GPIO). The MSS GPIO pin
functions as an input, output, tristate, or bidirectional buffer with configurable interrupt
generation and Schmitt trigger support. Input and output signal levels are compatible
with the I/O standard selected.
Unused GPIO pins are tristated and do not include pull-up or pull-down resistors.
During power-up, the used GPIO pins are tristated with no pull-up or pull-down
resistors until Sys boot configures them.
Some of these pins are also multiplexed with integrated peripherals in the MSS (SPI,
I2C, and UART). These pins are located in Bank-2 (GPIO_16 to GPIO_31) for A2F060,
A2F200, and A2F500 devices.
GPIOs can be routed to dedicated I/O buffers (MSSIOBUF) or in some cases to the
FPGA fabric interface through an IOMUX. This allows GPIO pins to be multiplexed as
either I/Os for the FPGA fabric, the ARM® Cortex-M3 or for given integrated MSS
peripherals. The MSS peripherals are not multiplexed with each other; they are
multiplexed only with the GPIO block. For more information, see the General Purpose
I/O Block (GPIO) section in the SmartFusion Microcontroller Subsystem User’s Guide.

User I/O Naming Conventions
The naming convention used for each FPGA user I/O is Gmn/IOuxwByVz, where:
Gmn is only used for I/Os that also have CCC access—i.e., global pins. Refer to the "Global I/O Naming
Conventions" section on page 5-6.
u = I/O pair number in bank, starting at 00 from the northwest I/O bank and proceeding in a clockwise
direction.
x = P (positive) or N (negative) or S (single-ended) or R (regular, single-ended).
w = D (Differential Pair), P (Pair), or S (Single-Ended). D (Differential Pair) if both members of the pair
are bonded out to adjacent pins or are separated only by one GND or NC pin; P (Pair) if both members of
the pair are bonded out but do not meet the adjacency requirement; or S (Single-Ended) if the I/O pair is
not bonded out. For Differential Pairs (D), adjacency for ball grid packages means only vertical or
horizontal. Diagonal adjacency does not meet the requirements for a true differential pair.
B = Bank
y = Bank number starting at 0 from northwest I/O bank and incrementing clockwise.
V = Reference voltage
z = VREF mini bank number.
The FPGA user I/O pin functions as an input, output, tristate or bidirectional buffer. Input and output
signal levels are compatible with the I/O standard selected. Unused I/O pins are disabled by Libero SoC
software and include a weak pull-up resistor. During power-up, the used I/O pins are tristated with no
pull-up or pull-down resistors until I/O enable (there is a delay after voltage stabilizes, and different I/O
banks power up sequentially to avoid a surge of ICCI).
Unused I/Os are configured as follows:
•
Output buffer is disabled (with tristate value of high impedance)
•
Input buffer is disabled (with tristate value of high impedance)
•
Weak pull-up is programmed
Some of these pins are also multiplexed with integrated peripherals in the MSS (Ethernet MAC and
external memory controller).
Unused MSS I/Os are neither weakly pulled-up nor weakly pulled-down. The Schmitt trigger is disabled.
Essentially, I/Os have the reset values as defined in Table 19-25 IOMUX_n_CR, in the SmartFusion
Microcontroller Subsystem User's Guide.
By default, during programming I/Os become tristated and weakly pulled up to VCCxxxxIOBx. You can
modify the I/O states during programming in FlashPro. For more details, refer to "Specifying I/O States
During Programming" on page 1-3. With the VCCI and VCC supplies continuously powered up, when the
device transitions from programming to operating mode, the I/Os are instantly configured to the desired
user configuration. For more information, see the SmartFusion FPGA User I/Os section in the
SmartFusion FPGA Fabric User’s Guide.

Pin Descriptions
JTAG Pins
SmartFusion cSoCs have a separate bank for the dedicated JTAG pins. The JTAG pins can be run at any
voltage from 1.5 V to 3.3 V (nominal). VCC must also be powered for the JTAG state machine to operate,
even if the device is in bypass mode; VJTAG alone is insufficient. Both VJTAG and VCC to the
SmartFusion cSoC part must be supplied to allow JTAG signals to transition the SmartFusion cSoC.
Isolating the JTAG power supply in a separate I/O bank gives greater flexibility with supply selection and
simplifies power supply and PCB design. If the JTAG interface is neither used nor planned to be used,
the VJTAG pin together with the TRSTB pin could be tied to GND.

Description
JTAG controller selection
Depending on the state of the JTAGSEL pin, an external JTAG controller will either
see the FPGA fabric TAP/auxiliary TAP (High) or the Cortex-M3 JTAG debug
interface (Low).
The JTAGSEL pin should be connected to an external pull-up resistor such that the
default configuration selects the FPGA fabric TAP.
TCK

Serial input for JTAG boundary scan, ISP, and UJTAG. The TCK pin does not have an
internal pull-up/-down resistor. If JTAG is not used, it is recommended to tie off TCK
to GND or VJTAG through a resistor placed close to the FPGA pin. This prevents
JTAG operation in case TMS enters an undesired state.
Note that to operate at all VJTAG voltages, 500 Ω to 1 kΩ will satisfy the requirements.
Refer to Table 5-1 on page 5-11 for more information.

TRSTB
In
HIGH
Boundary scan reset pin
The TRST pin functions as an active low input to asynchronously initialize (or reset)
the boundary scan circuitry. There is an internal weak pull-up resistor on the TRST
pin. If JTAG is not used, an external pull-down resistor could be included to ensure
the TAP is held in reset mode. The resistor values must be chosen from Table 5-1 on
page 5-11 and must satisfy the parallel resistance value requirement. The values in
Table 5-1 on page 5-11 correspond to the resistor recommended when a single
device is used. The values correspond to the equivalent parallel resistor when
multiple devices are connected via a JTAG chain.
In critical applications, an upset in the JTAG circuit could allow entering an undesired
JTAG state. In such cases, it is recommended that you tie off TRST to GND through a
resistor placed close to the FPGA pin.
The TRSTB pin also resets the serial wire JTAG – debug port (SWJ-DP) circuitry
within the Cortex-M3.
Can be left floating when unused.

Notes:
1. Shading denotes pins that do not have completely identical functions from density to density. For example, the bank
assignment can be different for an I/O, or the function might be available only on a larger density device.
2. *: Indicates that the signal assigned to the pins as a CLKBUF/CLKBUF_LVPECL/CLKBUF_LVDS goes through a
glitchless mux. In order for the glitchless mux to operate correctly, the signal must be a free-running clock signal. Refer to
the ’Glitchless MUX’ section in the SmartFusion Microcontroller Subsystem User’s Guide for more details.

Notes:
1. Shading denotes pins that do not have completely identical functions from density to density. For example, the bank
assignment can be different for an I/O, or the function might be available only on a larger density device.
2. *: Indicates that the signal assigned to the pins as a CLKBUF/CLKBUF_LVPECL/CLKBUF_LVDS goes through a
glitchless mux. In order for the glitchless mux to operate correctly, the signal must be a free-running clock signal. Refer to
the ’Glitchless MUX’ section in the SmartFusion Microcontroller Subsystem User’s Guide for more details.

2. *: Indicates that the signal assigned to the pins as a CLKBUF/CLKBUF_LVPECL/CLKBUF_LVDS goes through a
glitchless mux. In order for the glitchless mux to operate correctly, the signal must be a free-running clock signal. Refer
to the ’Glitchless MUX’ section in the SmartFusion Microcontroller Subsystem User’s Guide for more details.

Notes:
1. Shading denotes pins that do not have completely identical functions from density to density. For example, the bank
assignment can be different for an I/O, or the function might be available only on a larger density device.
2. *: Indicates that the signal assigned to the pins as a CLKBUF/CLKBUF_LVPECL/CLKBUF_LVDS goes through a
glitchless mux. In order for the glitchless mux to operate correctly, the signal must be a free-running clock signal. Refer to
the ’Glitchless MUX’ section in the SmartFusion Microcontroller Subsystem User’s Guide for more details.

Notes:
1. Shading denotes pins that do not have completely identical functions from density to density. For example, the bank
assignment can be different for an I/O, or the function might be available only on a larger density device.
2. *: Indicates that the signal assigned to the pins as a CLKBUF/CLKBUF_LVPECL/CLKBUF_LVDS goes through a
glitchless mux. In order for the glitchless mux to operate correctly, the signal must be a free-running clock signal. Refer
to the ’Glitchless MUX’ section in the SmartFusion Microcontroller Subsystem User’s Guide for more details.
