A3PE600-PQ208I

A3PE600-PQ208I - 600K-Gate Flash FPGA, 147 I/O | Microchip

The Microchip (Microsemi) A3PE600-PQ208I is a ProASIC3E family flash-based FPGA offering 600,000 system gates, 147 user I/Os, and 110,592 bits of true dual-port SRAM, housed in a 208-pin BFQFP (PQ208) surface-mount package with an industrial temperature range of -40C to +100C. Its core supply operates from 1.425V to 1.575V. A flash-based FPGA is a field-programmable gate array whose configuration is stored in on-chip nonvolatile flash memory rather than an external configuration device. Within the programmable logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), flash FPGAs occupy a distinct niche: they are Instant On at power-up, retain their programmed design when power is removed, and require no external boot flash, unlike SRAM FPGAs from Xilinx or Intel/Altera. Key features include reprogrammable 130-nm, 7-layer metal (6 copper) flash-based CMOS technology, a single-chip solution with low total cost of ownership, up to 231 MHz system performance, on-chip user nonvolatile memory, and support for Level 0 instant-on operation. The ProASIC3E fabric combines logic tiles with embedded true dual-port SRAM blocks (108 kbits on this device), enabling FIFOs, buffers, and register files without external memory. Architecturally, the A3PE600 uses a sea-of-tiles fabric of VersaTiles, each configurable as combinational or sequential logic, with flash switches providing nonvolatility and inherent security benefits: no bitstream is streamed at power-up, making reverse engineering significantly harder than SRAM FPGAs. Typical applications include industrial automation and motor control, aerospace and defense systems requiring instant-on secure configuration, medical instrumentation, and communications line cards, where single-chip nonvolatile programmable logic reduces BOM cost and board complexity. A key design consideration is power: the 1.5V core rail must be tightly regulated within 1.425V to 1.575V, and I/O bank voltages must be planned early since the 147 user I/Os are grouped into banks.

Key differentiating features include the 5.0 V tolerant architecture that lets the MX directly interface with legacy 5V TTL/PLD systems without level shifting, the secure antifuse fabric that cannot be read back or re-programmed in the field, and speed-grade -2 timing supporting 146.3 MHz operation. The 101 available user I/O across the 160-pin BQFP gives ample connectivity for bus interfaces, glue logic consolidation, and legacy PLD integration. Technically, the MX fabric combines sequential modules, combinational modules, and decode modules with a routing architecture optimized for high logic utilization. Being one-time programmable, the device requires no configuration PROM and boots in microseconds, unlike SRAM FPGAs. Typical applications include consolidation of legacy 5V PLD/gate-array designs, industrial control, military/aerospace systems requiring configuration immunity, and high-reliability bridge logic. Designers should note that antifuse programming is permanent: thoroughly verify the design in simulation and with device programming services before committing production units. Power budgeting must account for the 5V core supply typical of this generation.
