Electrical Characteristics
1. Introduction
Microsemi®'s automotive grade SmartFusion®2 system-on-chip (SoC) field programmable gate array (FPGA) and
IGLOO®2 FPGA families offer the best-in-class security, industry leading high reliability and lowest static power in a
flash-based fabric. With a strong heritage of supplying to Military and Aviation customers, Microsemi automotive grade
devices are ideally suited to meet the demands of the automotive industry providing the lowest total-cost-of-ownership.
These next-generation devices integrate an industry standard 4-input lookup table-based (LUT) FPGA fabric with
integrated mathblocks, multiple embedded memory blocks, high-performance SERDES communications interfaces on
a single chip with extended temperature support.
Automotive grade SmartFusion2 and IGLOO2 devices offer up to 90 K Logic Elements, up to 5 MB of embedded RAM,
up to 4 SERDES lanes, up to 2 PCIe endpoints and integrated hard DDR3 memory controllers with single error correct
and double error detect. IGLOO2 automotive grade devices integrate a high-performance memory subsystem (HPMS)
with on-chip flash, 32 kbyte embedded SRAM, and multiple DMA controllers. SmartFusion2 automotive grade SoC
FPGAs provide a low-power real time microcontroller subsystem (MSS) with an embedded ARM® Cortex™-M3
encapsulating the benefits of HPMS along with a rich set of industry standard peripherals including Ethernet, USB, and
CAN.
SmartFusion2 and IGLOO2 FPGAs are the best alternative to ASICs and SRAM based FPGAs with their advantages
of Zero FIT reliability, tamper-free advanced security, industry's lowest static power and supply assurance for long
product lifetime support.

The temperature variable in the Microsemi 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.

4.3.2 Theta-JA
Junction-to-ambient thermal resistance (JA) 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 it is useful for
comparing the thermal performance of one package to another.
The maximum power dissipation allowed is calculated using EQ 4.
T J(MAX) – T A(MAX)
Maximum Power Allowed = ------------------------------------------- JA
EQ 4
The absolute maximum junction temperature is 125°C. EQ 5 shows a sample calculation of the absolute maximum
power dissipation allowed for the M2GL060TS-1FGG484 package at Automotive Grade 2 temperature and in still air,
where:
JA
= 15.4°C/W (taken from Table 7 on page 6).
TA
= 105°C
– 105°C- = 1.3 W
Maximum Power Allowed = 125°C
--------------------------------------15.4°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.
Revision 2
6
SmartFusion2 SoC and IGLOO2 FPGA Automotive Grade 2
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.
4.3.3 Theta-JB
Junction-to-board thermal resistance (JB) 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.
4.3.4 Theta-JC
Junction-to-case thermal resistance (JC) 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.

8.8. Differential I/O Standards
Configuration of the I/O modules as a differential pair is handled by Microsemi SoC Products Group Libero® Systemon-Chip (SoC) 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 registers (DDR).
8.8.1 LVDS
Low-Voltage Differential Signaling (ANSI/TIA/EIA-644) is a high-speed, differential I/O standard.

8.8.6 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. Similar to LVDS, two pins are needed. It also requires external resistor termination.
IGLOO2 and SmartFusion2 SoC FPGAs support only LVPECL receivers and do not support LVPECL transmitters.

changes to TX_AMP setting.
2. Based on Input Voltage Common-Mode (VICM) = 0 V. Requires AC Coupling.
23. PCIe Electrical and Timing AC and DC Characteristics
PCIe® is a high speed, packet-based, point-to-point, low pin count, serial interconnect bus. The IGLOO2 and
SmartFusion2 SoC FPGAs has up to four hard high-speed serial interface blocks. Each SERDES block contains a
PCIe system block. The PCIe system is connected to the SERDES block.

highlighted in Table 1 on page 1 is designated as either "Product Brief," "Advance," "Preliminary," or
"Production." The definitions of these categories are as follows:
Product Brief
The product brief is a summarized version of a datasheet (advance or production) and contains general
product information. This document gives an overview of specific device and family information.
Advance
This version contains initial estimated information based on simulation, other products, devices, or speed
grades. This information can be used as estimates, but not for production.
This label only applies to the DC and Switching Characteristics chapter of the datasheet and will only be
used when the data has not been fully characterized.
Preliminary
The datasheet contains information based on simulation and/or initial characterization. The information is
believed to be correct, but changes are possible.
Production
This version contains information that is considered to be final.
