1 – IGLOO2 Device Family Overview
Microsemi’s IGLOO2 FPGAs integrate fourth generation flash-based FPGA fabric and high-performance
communications interfaces on a single chip. The IGLOO2 family is the industry’s lowest power, highest reliability and
most secure programmable logic solution. This next generation IGLOO2 architecture offers up to 3.6X gate count,
implemented with 4-input look-up table (LUT) fabric with carry chains, giving 2X performance, and includes multiple
embedded memory options and mathblocks for DSP. High speed serial interfaces enable PCIe, while DDR2/DDR3
memory controllers provide high speed memory interfaces.
Reliability
IGLOO2 flash-based fabric has zero FIT configuration rate due to its single event upset (SEU) immunity, which is
critical in reliability applications. The flash fabric also has the advantage that no external configuration memory is
required, making the device instant-on; it retains configuration when powered off. To complement this unique FPGA
capability, IGLOO2 devices add reliability to many other aspects of the device. Single Error Correct Double Error
Detect (SECDED) protection is implemented on the embedded SRAM (eSRAM), and is optional on the DDR memory
controllers. This means that if a one-bit error is detected, it will be corrected. Errors of more than one bit are detected
only and not corrected. SECDED error signals are brought to the FPGA fabric to allow the user to monitor the status of
these protected internal memories. Other areas of the architecture are implemented with latches, which are more
resistant to SEUs. Therefore, no correction is needed in these locations: DDR bridges (HPMS, MDDR), SPI, and PCIe
FIFOs.
Highest Security Devices
Building further on the intrinsic security benefits of flash nonvolatile memory technology, the IGLOO2 family
incorporates essentially all the legacy security features that made the original SmartFusion®, Fusion®, IGLOO, and
ProASIC®3 third-generation flash FPGAs and cSoCs the gold standard for secure devices in the PLD industry. In
addition, the fourth-generation flash-based SmartFusion2 and IGLOO2 FPGAs add many unique design and data
security features and use models new to the PLD industry.
Design Security vs. Data Security
When classifying security attributes of programmable logic devices (PLDs), a useful distinction is made between
design security and data security.

IGLOO2 Device Family Overview
Design Security
Design security is protecting the intent of the owner of the design, such as keeping the design and associated
bitstream keys confidential, preventing design changes (for example, insertion of Trojan Horses), and controlling the
number of copies made throughout the device life cycle. Design security may also be known as intellectual property
(IP) protection. It is one aspect of anti-tamper (AT) protection. Design security applies to the device from initial
production, includes any updates such as in-the-field upgrades, and can include decommissioning of the device at the
end of its life, if desired. Good design security is a prerequisite for good data security.
The following are the main design security features supported.

Data Security
Data Security is protecting the information the FPGA is storing, processing, or communicating in its role in the end
application. If, for example, the configured design is implementing the key management and encryption portion of a
secure military radio, data security could entail encrypting and authenticating the radio traffic, and protecting the
associated application-level cryptographic keys. Data security is closely related to the terms information assurance (IA)
and information security. All IGLOO2 devices incorporate enhanced design security, making them the most secure
programmable logic devices ever made. Select IGLOO2 models also include an advanced set of on-chip data security
features that make designing secure information assurance applications easier and better than ever before.

Low Power
Microsemi’s flash-based FPGA fabric results in extremely low power design implementation with static power as low as
7.5 mW (for 6,060 LE device). Flash*Freeze (F*F) technology provides an ultra-low power static mode (Flash*Freeze
mode) for IGLOO2 devices, with power less than6.12 mW for the largest device (86,184 LE device). F*F mode entry
retains all the SRAM and register information and the exit from F*F mode achieves rapid recovery to active mode.

IGLOO2 Device Family Overview
High-Performance FPGA Fabric
Built on 65 nm process technology, the IGLOO2 FPGA fabric is composed of four building blocks: the logic module, the
large SRAM, the micro SRAM and the mathblock. The logic module is the basic logic element and has advanced
features:
•
A fully permutable 4-input LUT (look-up table) optimized for lowest power
•
A dedicated carry chain based on carry look-ahead technique
•
A separate flip-flop which can be used independently from the LUT
The 4-input look-up table can be configured either to implement any 4-input combinatorial function or to implement an
arithmetic function where the LUT output is XORed with carry input to generate the sum output.
Dual-Port Large SRAM (LSRAM)
Large SRAM (RAM1Kx18) is targeted for storing large memory for use with various operations. Each LSRAM block
can store up to 18,432 bits. Each RAM1Kx18 block contains two independent data ports: Port A and Port B. The
LSRAM is synchronous for both Read and Write operations. Operations are triggered on the rising edge of the clock.
The data output ports of the LSRAM have pipeline registers which have control signals that are independent of the
SRAM’s control signals.
Three-Port Micro SRAM (uSRAM)
Micro SRAM (RAM64x18) is the second type of SRAM which is embedded in the fabric of IGLOO2 devices.
RAM64x18 uSRAM is a 3-port SRAM; it has two read ports (Port A and Port B) and one write port (Port C). The two
read ports are independent of each other and can perform Read operations in both synchronous and asynchronous
modes. The write port is always synchronous. The uSRAM block is approximately 1 KB (1,152 bits) in size. These
uSRAM blocks are primarily targeted for building embedded FIFOs to be used by any embedded fabric masters.
Mathblocks for DSP Applications
The fundamental building block in any digital signal processing algorithm is the multiply-accumulate function. The
IGLOO2 device implements a custom 18x18 Multiply-Accumulate (18x18 MACC) block for efficient implementation of
complex DSP algorithms such as finite impulse response (FIR) filters, infinite impulse response (IIR) filters, and fast
Fourier transform (FFT) for filtering and image processing applications.
Each mathblock has the following capabilities:
•
Supports 18x18 signed multiplications natively (A[17:0] x B[17:0])
•
Supports dot product; the multiplier computes:
(A[8:0] x B[17:9] + A[17:9] x B[8:0]) x 29
•
Built-in addition, subtraction, and accumulation units to combine multiplication results efficiently
In addition to the basic MACC function, DSP algorithms typically need small amounts of RAM for coefficients and
larger RAMs for data storage. IGLOO2 micro RAMs are ideally suited to serve the needs of coefficient storage while
the large RAMs are used for data storage.
HPMS
HPMS embeds two separates 32 KByte SRAM blocks that have optional SECDED capabilities (32 KBytes with
SECDED enabled, 40 KBytes with SECDED disabled), up to two separate 256 KByte eNVM (flash) blocks, and two
separate DMA controllers for fast DMA user logic offloading. The HPMS provides multiple interfacing options to the
FPGA fabric in order to facilitate tight integration between the HPMS and user logic in the fabric.

DDR Bridge
The DDR bridge is a data bridge between two AHB bus masters and a single AXI bus slave. The DDR bridge
accumulates AHB writes into write combining buffers prior to bursting out to external DDR memory. The DDR bridge
also includes read combining buffers, allowing AHB masters to efficiently read data from the external DDR memory
from a local buffer. The DDR bridge optimizes reads and writes from multiple masters to a single external DDR
memory. Data coherency rules between the masters and the external DDR memory are implemented in hardware. The
DDR bridge contains two write combining / read buffers. All buffers within the DDR bridge are implemented with SEU
tolerant latches and are not subject to the single event upsets (SEUs) that SRAM exhibits. IGLOO2 devices implement
two DDR bridges in the HPMS, and MDDR subsystems.
AHB Bus Matrix (ABM)
The AHB bus matrix (ABM) is a non-blocking, AHB-Lite multi-layer switch, supporting 4 master interfaces and 8 slave
interfaces. The switch decodes access attempts by masters to various slaves, according to the memory map and
security configurations. When multiple masters are attempting to access a particular slave simultaneously, an arbiter
associated with that slave decides which master gains access, according to a configurable set of arbitration rules.
These rules can be configured by the user to provide different usage patterns to each slave. For example, a number of
consecutive access opportunities to the slave can be allocated to one particular master, to increase the likelihood of
same type accesses (all reads or all writes), which makes more efficient usage of the bandwidth to the slave.
Fabric Interface Controller (FIC)
The FIC block provides separate interfaces between the HPMS and the FPGA fabric: the HPMS master (MM) and
fabric master (FM). Each of these interfaces can be configured to operate as AHB-Lite or APB3. Depending on device
density, there are up to two FIC blocks present in the HPMS (FIC_0 and FIC_1).
eSRAM
The HPMS contains two blocks of 32 KB eSRAM, giving a total of 64 KB. Having the eSRAM arranged as two separate
blocks allows the user to take advantage of the parallelism that exists in the HPMS.
The eSRAM is designed for Single Error Correct Double Error Detect (SECDED) protection. When SECDED is
disabled, the SRAM usually used to store SECDED data may be reused as an extra 16 KB of eSRAM.
eNVM
The HPMS contains up to 512 KB of eNVM (64 bits wide).
DMA Engines
Two DMA engines are present in the HPMS: high-performance DMA and peripheral DMA.
HPDMA
The high-performance DMA (HPDMA) engine provides efficient memory to memory data transfers between an
external DDR memory and internal eSRAM. This engine has two separate AHB-Lite interfaces—one to the MDDR
bridge and the other to the AHB bus matrix. All transfers by the HPDMA are full word transfers.
PDMA
The peripheral DMA engine (PDMA) is tuned for offloading byte-intensive operations, involving HPMS peripherals, to
and from the internal eSRAMs. Data transfers can also be targeted to user logic/RAM in the FPGA fabric.
APB Configuration Bus
On every IGLOO2 device memory, an APB configuration bus is present to allow the user to initialize the SERDES
ASIC blocks, the fabric DDR memory controller, and user instantiated peripherals in the FPGA fabric.

IGLOO2 Device Family Overview
Peripherals
A large number of communications and general purpose peripherals are implemented in the HPMS.
Communication Block (COMM_BLK)
The COMM block provides a UART-like communications channel between the HPMS and the system controller.
System services are initiated through the COMM block. System services such as Enter Flash*Freeze Mode are
initiated though this block.
SPI
The SPI controller is compliant with the Motorola SPI, Texas Instruments synchronous serial, and National
Semiconductor MICROWIRE™ formats. In addition, the SPI supports interfacing to large SPI flash and EEPROM
devices by way of the slave protocol engine. The SPI controller supports both Master and Slave modes of operation.
The SPI controller embeds two 4×32 (depth × width) FIFOs for receive and transmit. These FIFOs are accessible
through RX data and TX data registers. Writing to the TX data register causes the data to be written to the transmit
FIFO. This is emptied by transmit logic. Similarly, reading from the RX data register causes data to be read from the
receive FIFO.
Clock Sources: On-Chip Oscillators, PLLs, and CCCs
IGLOO2 devices have two on-chip RC oscillators—a 1 MHz RC oscillator and a 50 MHz RC oscillator—and the main
crystal oscillator (32 kHz–20 MHz). These are available to the user for generating clocks to the on-chip resources and
the logic built on the FPGA fabric array. These oscillators can be used in conjunction with the integrated user phaselocked loops (PLLs) and FAB_CCCs to generate clocks of varying frequency and phase. In addition to being available
to the user, these oscillators are also used by the system controller, power-on reset circuitry, and HPMS during the
Flash*Freeze mode.
IGLOO2 devices have up to six fabric CCC (FAB_CCC) blocks and a dedicated PLL associated with each CCC to
provide flexible clocking to the FPGA fabric portion of the device. The user has the freedom to use any of the six PLLs
and CCCs to generate the fabric clocks and the internal HPMS clock from the base fabric clock (CLK_BASE). There is
also a dedicated CCC block for the HPMS (HPMS_CCC) and an associated PLL (MPLL) for HPMS clocking and deskewing the CLK_BASE clock. The fabric alignment clock controller (FACC), part of the HPMS CCC, is responsible for
generating various aligned clocks required by the HPMS for correct operation of the HPMS blocks and synchronous
communication with the user logic in the FPGA fabric.

MDDR Subsystem
The MDDR subsystem has two interfaces to the DDR. One is an AXI 64-bit bus from the DDR bridge within the HPMS.
The other is a multiplexed interface from the FPGA fabric, which can be configured as either a single AXI 64-bit bus or
two 32-bit AHB-Lite buses. There is also a 16-bit APB configuration bus, which is used to initialize the majority of the
internal registers within the MDDR subsystem after reset. This APB configuration bus is mastered by a master in the
FPGA fabric. Support for 3.3 V Single Data Rate DRAMs (SDRAM) can be obtained by instantiating a soft AHB or AXI
SDRAM memory controller in the FPGA fabric and connecting I/O ports to 3.3 V MSIO.
