M1AFS250-1PQ208 - Fusion FPGA 250K Gates 93 I/O | Microchip

The Microsemi (now Microchip Technology) M1AFS250-1PQ208 is a Fusion mixed-signal FPGA delivering 250,000 system gates, 36,864 bits of flash-based user RAM, and 93 programmable I/O in a 208-pin BFQFP (PQ208) quad flat package operating from a nominal 1.5V core supply. A field-programmable gate array (FPGA) is a semiconductor device containing a matrix of configurable logic blocks and programmable interconnects that the designer wires together to implement custom digital circuits after manufacturing. FPGAs sit at the application-specific level of the programmable logic hierarchy - above CPLDs in density and below full ASICs in volume economics - and the Fusion family uniquely integrates flash-based programmable logic with configurable analog blocks, clock generation and management circuitry, and large flash memory blocks in a single monolithic die. Key features of the M1AFS250 include monolithic integration of configurable analog peripherals, flash-based fabric that retains its configuration in power-off (no external boot PROM required), comprehensive on-chip clock conditioning, and 36,864 RAM bits for distributed data buffering. The flash-based architecture also provides inherently secure, single-chip configuration, a distinguishing advantage over SRAM FPGAs. Technically, the device is fabricated on a 130nm CMOS process with the fabric clocked up to approximately 1282 MHz internal paths reported by distributor data, and the core operates within a 1.425V to 1.575V window. The 208-pin PQFP uses 0.5mm gull-wing terminal pitch in a square body for surface-mount assembly. Typical applications include industrial automation controllers, telecommunications infrastructure line cards, mixed-signal system monitoring, and embedded computing where integrated analog and flash storage reduce board-level component count. Design consideration: because this part is RoHS non-compliant and contains lead, it is restricted to exempt/legacy applications; plan end-of-life migration strategy accordingly.

A fusion mixed-signal FPGA is a field-programmable gate array that combines flash-based programmable fabric with analog peripherals, flash memory blocks, and clock management on one monolithic die. Within the power/processing hierarchy, this places the M1AFS250 as a system-on-chip (SoC): FPGA fabric plus an ARM Cortex-M1 soft-processor core running at up to 350 MHz, bridging programmable logic and embedded MCU control without a discrete microcontroller. Key features include 250K system gates (approximately 6,144 logic cells per the Microchip USA listing), 114 user I/O, comprehensive on-chip clock generation and management circuitry, and large flash memory blocks. The monolithic integration of configurable analog and digital fabric reduces board area and bill-of-materials count for mixed-signal control systems. Technically, the M1AFS250 family is manufactured on a 130nm flash-based process (per Jotrin Electronics), offering nonvolatile, secure, instant-on configuration without an external configuration PROM. The FG256 package is a 1.00 mm ball pitch 256-ball BGA, surface-mount (SMD/SMT), supplied in tray packaging. Commercial temperature range is 0C to +70C. Note that this exact ordering code is RoHS non-compliant and contains lead; the FGG256 (Green) variant is the lead-free drop-in alternative on the same footprint. Typical applications include industrial automation control, smart power motor control, portable instrumentation, and embedded systems requiring single-chip analog monitoring plus logic. The 1.5V core and flash fabric suit low-power, high-reliability designs. Design consideration: verify the FGG256 (RoHS-compliant) alternative early, since the FG256 leaded version may face procurement and environmental restrictions in new designs.
