1 – Military ProASIC3/EL Device Family Overview
General Description
† Flash*Freeze technology is not supported on A3P1000.
The military ProASIC3/EL family of Actel flash FPGAs dramatically reduces dynamic power consumption
by 40% and static power by 50%. These power savings are coupled with performance, density, true
single chip, 1.2 V to 1.5 V core and I/O operation, reprogrammability, and advanced features.
Actel's proven Flash*Freeze technology enables military ProASIC3EL device users to shut off dynamic
power instantaneously and switch the device to static mode without the need to switch off clocks or
power supplies, and retaining internal states of the device. This greatly simplifies power management. In
addition, optimized software tools using power-driven layout provide instant push-button power
reduction.
Nonvolatile flash technology gives military ProASIC3/EL devices the advantage of being a secure, low-
power, single-chip solution that is live at power-up (LAPU). Military ProASIC3/EL devices offer dramatic
dynamic power savings, giving FPGA users flexibility to combine low power with high performance.
These features enable designers to create high-density systems using existing ASIC or FPGA design
flows and tools.
Military ProASIC3/EL devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as
well as clock conditioning circuitry (CCC) based on an integrated phase-locked loop (PLL). Military
ProASIC3/EL devices support devices from 600 k system gates to 3 million system gates with up to 504
kbits of true dual-port SRAM and 620 user I/Os.
M1 military ProASIC3/EL devices support the high-performance, 32-bit Cortex-M1 processor developed
by ARM for implementation in FPGAs. ARM Cortex-M1 is a soft processor that is fully implemented in the
FPGA fabric. It has a three-stage pipeline that offers a good balance between low-power consumption
and speed when implemented in an M1 military ProASIC3/EL device. The processor runs the ARMv6-M
instruction set, has a configurable nested interrupt controller, and can be implemented with or without the
debug block. ARM Cortex-M1 is available at no cost from Actel for use in M1 military
ProASIC3/ELFPGAs.
The ARM-enabled devices have Actel ordering numbers that begin with M1 and do not support AES
decryption.
Flash*Freeze Technology
Military ProASIC3EL devices offer Actel's proven Flash*Freeze technology, which allows instantaneous
switching from an active state to a static state. When Flash*Freeze mode is activated, military
ProASIC3EL devices enter a static state while retaining the contents of registers and SRAM. Power is
conserved without the need for additional external components to turn off I/Os or clocks. Flash*Freeze
technology is combined with in-system programmability, which enables users to quickly and easily
upgrade and update their designs in the final stages of manufacturing or in the field. The ability of military
ProASIC3EL devices to support a 1.2 V core voltage allows for an even greater reduction in power
consumption, which enables low total system power.
When the military ProASIC3EL device enters Flash*Freeze mode, the device automatically shuts off the
clocks and inputs to the FPGA core; when the device exits Flash*Freeze mode, all activity resumes and
data is retained.
The availability of low-power modes, combined with a reprogrammable, single-chip, single-voltage
solution, make military ProASIC3EL devices suitable for low-power data transfer and manipulation in
military-temperature applications where available power may be limited (e.g., in battery-powered
equipment); or where heat dissipation may be limited (e.g., in enclosures with no forced cooling).
