datasheet.
IGLOO2 FPGA and SmartFusion2 SoC FPGA
Microsemi Proprietary and Confidential DS0128 Datasheet Revision 12.0 5
2 IGLOO2 FPGA and SmartFusion2 SoC FPGA
Microsemi’s mainstream SmartFusion®2 SoC and IGLOO®2 FPGA families integrate an industry
standard 4-input lookup table-based (LUT) FPGA fabric with integrated math blocks, multiple embedded
memory blocks, and high-performance SerDes communication interfaces on a single chip. Both families
benefit from low-power flash technology and are the most secure and reliable FPGAs in the industry.
These next generation devices offer up to 150K Logic Elements, up to 5 MBs of embedded RAM, up to
16 SerDes lanes, and up to four PCI Express Gen 2 endpoints, as well as integrated hard DDR3 memory
controllers with error correction.
SmartFusion2 devices integrate an entire low-power, real-time microcontroller subsystem (MSS) with a
rich set of industry-standard peripherals including Ethernet, USB, and CAN, while IGLOO2 devices
integrate a high-performance memory subsystem with on-chip flash, 32 Kbyte embedded SRAM, and
multiple DMA controllers.

2.3.1.1 Overshoot/Undershoot Limits
For AC signals, the input signal may undershoot during transitions to –1.0 V for no longer than 10% of
the period. The current during the transition must not exceed 100 mA.
For AC signals, the input signal may overshoot during transitions to VCCI + 1.0 V for no longer than 10%
of the period. The current during the transition must not exceed 100 mA.
Note: The above specifications do not apply to the PCI standard. The IGLOO2 and SmartFusion2 PCI I/Os are
compliant with the PCI standard including the PCI overshoot/undershoot specifications.
2.3.1.2 Thermal Characteristics
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 causes the chip's junction temperature to be higher than the
ambient, case, or board temperatures.
EQ1 through EQ3 give the relationship between thermal resistance, temperature gradient, and power.

2.3.1.2.1 Theta-JA
Junction-to-ambient thermal resistance (JA) is determined under standard conditions specified by
JEDEC (JESD-51), but it has little relevance in the actual performance of the product. It must be used
with caution, but it is useful for comparing the thermal performance of one package with another.
The maximum power dissipation allowed is calculated using EQ4.
EQ 4
The absolute maximum junction temperature is 100 °C. EQ5 shows a sample calculation of the absolute
maximum power dissipation allowed for the M2GL050T-FG896 package at commercial temperature and
in still air, where:
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
may be attached to the top of the case, or the airflow inside the system must be increased.
2.3.1.2.2 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 the junction to the 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.
2.3.1.2.3 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 to packages used with
external heat sinks. Constant temperature is applied to the surface, which 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.

2.3.6 Memory Interface and Voltage Referenced I/O Standards
This section describes High-Speed Transceiver Logic (HSTL) memory interface and voltage reference
I/O standards.
2.3.6.1 High-Speed Transceiver Logic (HSTL)
The HSTL standard is a general purpose high-speed bus standard sponsored by IBM (EIA/JESD8-6).
IGLOO2 FPGA and SmartFusion2 SoC FPGA devices support two classes of the 1.5 V HSTL. These
differential versions of the standard require a differential amplifier input buffer and a push-pull output
buffer.

1. when VID is < 300 mV, the input signal is delayed by up to an additional 450 ps for
LVDS25 and 280 ps for LVDS33. This delay is not accounted in the timing model. Clock
insertion delays, propagation delays, and I/O to FF delays are marginally affected. Adding
a parallel termination resistor of 200 ohms +/- 5% across the receiver pins can mitigate
this additional delay when VID is < 300 mV.

2.3.7.6 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.
