M1A3P1000-1PQ208M Datasheet, PDF (7/212 Pages) Microsemi Corporation – Military ProASIC3/EL Low Power Flash FPGAs with Flash*Freeze Technology

1 – Military ProASIC3/EL Device Family Overview
General Description
The military ProASIC3/EL family of 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.
Microsemi’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 250K 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 Microsemi for use in M1 military ProASIC3/EL
FPGAs.
The ARM-enabled devices have ordering numbers that begin with M1 and do not support AES
decryption.
Flash*Freeze Technology^†
Military ProASIC3EL devices offer 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).
† Flash*Freeze technology is not supported on A3P1000.
