A3P250-PQG208 概要

The Microchip A3P250-PQG208 is a ProASIC3 flash-based Field Programmable Gate Array (FPGA) delivering 250K system gates with 36,864 bits of embedded SRAM and 151 user I/Os, packaged in a 208-pin Plastic Quad Flat Pack (PQFP/208-BFQFP) measuring 28 x 28 mm. Built on a non-volatile flash process, the device offers instant-on configuration in under 1 ms without an external boot PROM, and supports reprogramming in-system via JTAG or system-serial paths. The ProASIC3 architecture combines a versatile VersaTile element that can function as either a 3-input LUT or a D-flip-flop with enable, enabling efficient logic packing for state machines, datapath functions, and glue logic.

What is an FPGA? A Field Programmable Gate Array is a reconfigurable semiconductor device that allows designers to implement arbitrary digital logic through programmable lookup tables, routing fabric, and I/O cells. FPGAs sit between ASICs (Application-Specific ICs) and microcontrollers in the design hierarchy: microcontrollers run software sequentially, ASICs implement fixed logic, while FPGAs execute parallel hardware-defined logic with sub-nanosecond deterministic timing. Within the broader taxonomy, an FPGA belongs to programmable logic devices (PLD), which also include CPLDs (Complex PLDs) - smaller, non-volatile, less I/O-rich parts.

Key features of the A3P250-PQG208 include 6,144 VersaTiles, embedded FlashLock security for AES bitstream encryption, 1.5V core operation with multi-voltage I/O support (1.5V, 1.8V, 2.5V, 3.3V), and on-chip PLLs for clock management. The flash-based fabric eliminates the boot-configuration power surge typical of SRAM-based FPGAs, making it suitable for power-sequenced systems.

Typical applications include industrial control and motor drive logic, telecom interface bridges, avionics and military secure systems, medical imaging preprocessing, automotive body electronics, and consumer video processing. The wide I/O count makes it useful for legacy system glue logic and parallel bus interfacing.

When selecting the A3P250-PQG208, engineers should weigh its non-volatility and instant-on behavior against the higher per-unit cost of flash FPGAs versus SRAM-based equivalents. Its 208 PQFP footprint is also more accessible for hand-prototyping and rework than BGA variants.

Legacy Parallel Bus Glue Logic

The A3P250-PQG208 fits legacy parallel-bus glue-logic replacement because its 151 I/Os and flexible I/O voltage banks bridge ISA, PCI, VME, or proprietary parallel buses without external transceivers. Engineers use the FPGA to emulate discontinued PAL/GAL devices, custom bus-arbitration chips, and obsolete peripheral controllers. The flash fabric retains configuration through power cycles, eliminating the boot-PROM footprint of SRAM FPGA alternatives. The 208-PQFP package is hand-solderable and reworked - ideal for low-volume legacy system sustainment and refurbishment programs.

The 208-PQFP uses gull-wing leads on a 0.5 mm pitch around a 28 x 28 mm body, with pin 1 indicator at the corner. Detailed per-bank voltage groupings are shown in the datasheet pin tables.

What are the key specifications of A3P250-PQG208 that engineers should know?

The A3P250-PQG208 key specs are: 250,000 system gates, 6,144 VersaTiles (3-input LUT or D-FF), 36,864 bits embedded SRAM, 151 user I/Os, 208-PQFP 28x28 mm package, 1.5V core with 1.5/1.8/2.5/3.3V I/O, on-chip PLLs, AES FlashLock security, JTAG and system-serial configuration, instant-on flash fabric, and commercial 0C to +70C temperature grade.

Is A3P250-PQG208 suitable for motor drive applications?

Yes, the A3P250-PQG208 is widely used for industrial motor control glue logic, encoder decoding, and PWM generation. Its 151 user I/Os accommodate multiple quadrature encoder inputs, Hall-sensor banks, and gate-driver interface signals. According to the Microchip A3P250 product page, the device's industrial temperature range and instant-on behavior make it ideal for deterministic motor control startup.

What is the best cross-brand equivalent for A3P250-PQG208?

True cross-brand drop-in equivalents for the A3P250-PQG208 in the same 208-PQFP package are extremely limited because ProASIC3's pinout is Microchip/Actel-specific. Per the Alternatives Cross-Reference Data, no verified cross-brand drop-in 208-PQFP part exists in web data. Engineers seeking pin compatibility should consider same-Microchip variants (PQG208I industrial grade) or migrate to Lattice or Xilinx equivalents with PCB rework.

A3P250-PQG208 vs A3P250-PQG208I - which is better for industrial design?

For industrial applications, the A3P250-PQG208I is the better choice because it operates from -40C to +85C versus the commercial 0C to +70C range of the standard PQG208. Both share the same 208-PQFP package and silicon, so the I-suffix is a drop-in upgrade. Source: DigiKey listing and Xecor parametric comparison confirm the only meaningful difference is the temperature grade.

選定ガイド

Choose the A3P250-PQG208 when you need a non-volatile instant-on ProASIC3 FPGA in a hand-solderable 208-PQFP footprint for commercial-temperature (0C to +70C) applications such as industrial motor control glue logic, telecom interface bridging, or legacy parallel-bus replacement. Upgrade to the A3P250-PQG208I if your enclosure exceeds 70C or you operate below 0C, since it shares the identical footprint and bitstream. For aerospace or DO-254 designs, specify the A3P250-PQG208ES enhanced-screening variant. Avoid migrating to the PQ208 (non-G) variant without first verifying the I/O map - the G-suffix variant exposes 151 I/Os while the non-G exposes a smaller bank set. Cross-brand 208-PQFP drop-in parts do not exist in web data; PCB rework is required to migrate to Lattice or Xilinx equivalents.

設計ノート

The A3P250-PQG208 requires a stable 1.5V core supply (VCC_CORE) and per-bank I/O supplies (VCC1 through VCC8) at 1.5V, 1.8V, 2.5V, or 3.3V. Decouple each VCC pin with a 0.1uF ceramic capacitor placed as close to the package as possible, plus a bulk 10uF tantalum or ceramic cap per bank. The VPUMP pin needs 3.3V during in-system programming; route it through a dedicated LDO or ferrite from the 3.3V rail to avoid noise coupling into user I/Os during JTAG operations.

Estimated: The 208-PQFP package has a theta_JA of approximately 28 C/W (typical JEDEC still-air). At maximum commercial-grade loading (assuming 70% utilization at 1.5V core and active I/O switching), expect up to 700 mW dissipation. Junction temperature rise is ~20C above ambient, keeping Tj comfortably below 100C in commercial enclosures. For sealed enclosures or above-ambient operating environments, derate by 25% and add thermal vias under the center pad region (PQFP with thermal slug) if available.

Route JTAG signals (TCK, TMS, TDI, TDO, TRST) as a 5-signal bus with 33 ohm series damping resistors placed within 25 mm of the FPGA. Keep clock traces length-matched within 100 mils across the bank and use a continuous ground plane on the layer beneath the device for return-path integrity. The 208-PQFP uses 0.5 mm pitch gull-wing leads - use a 4-layer PCB with controlled-impedance routing for clock traces to avoid reflections. Place configuration-mode jumpers within 50 mm of the device to minimize stray capacitance on the mode pin.

Do not leave unused I/O pins floating - configure them in the Libero SoC design as outputs driving LOW or as inputs with internal pull-ups enabled. Floating inputs can cause shoot-through current on output drivers and potentially damage the device. Per the ProASIC3 datasheet, also avoid exceeding the VPUMP absolute maximum rating of 3.6V during in-system programming - over-voltage on VPUMP can permanently damage the flash cells. Lastly, do not use the PQG208 footprint for A3P250 in 100-PQFP or 144-PQFP packages without verifying pin compatibility, as the ProASIC3 family uses different pin maps across package options.
