M1A3P400-2PQG208I

The M1A3P400-2PQG208I is a ProASIC3 field programmable gate array (FPGA) from Microchip Technology designed as a secure, low-power, single-chip reprogrammable solution. This device integrates on-chip nonvolatile flash-based logic with a substantial I/O count and embedded memory, making it suitable for industrial designs and space-constrained, surface-mount PCB implementations.

Typical use cases include control, interface, and signal-processing roles where a combination of reprogrammability, low core-voltage operation, and industrial temperature range are required. The device delivers a balance of logic density, embedded memory, and mixed-voltage I/O flexibility for embedded and industrial applications.

Key Features

• Logic Density — 9,216 logic elements (LEs) supporting up to 400,000 equivalent system gates, enabling mid-range FPGA designs.
• Embedded Memory — Total on-chip RAM of 55,296 bits (approximately 55 kbits) for FIFOs, state storage, and small buffers.
• I/O Capacity — 151 user I/Os with support for mixed-voltage operation as described for the ProASIC3 family, suitable for multi-voltage system interfacing.
• Nonvolatile, Reprogrammable Flash — Flash-based FPGA architecture provides instant-on capability and retains programmed configuration when powered off (series-level capability).
• Security and In-System Programming — Series features include on-chip AES-based ISP and FlashLock security mechanisms for secure configuration and JTAG-based programming (as described in the ProASIC3 dataset).
• Power and Voltage — Core supply range of 1.425 V to 1.575 V for low-voltage operation; supports surface-mount assembly.
• Package and Mounting — 208-pin BFQFP package (supplier package listed as 208-PQFP, 28 × 28 mm) for compact board designs.
• Industrial Temperature Grade — Rated operating temperature: −40 °C to 100 °C, suitable for a broad range of industrial environments.
• RoHS Compliance — Device is RoHS-compliant for environmental regulatory needs.

Typical Applications

• Industrial Control — Implement deterministic control logic, custom interfaces, and mid-density signal processing within industrial equipment using the device’s industrial temperature rating.
• Embedded Systems — Replace ASSPs or create flexible glue logic and protocol bridges where reprogrammability and on-chip nonvolatile configuration are advantageous.
• Consumer and Portable Electronics — Use the low-voltage core and flash-based instant-on behavior for compact, battery-backed, or space-constrained products.
• Secure Configuration and In-System Updates — Leverage the ProASIC3 series’ AES-based ISP and FlashLock features to protect intellectual property and enable secure field updates.

Unique Advantages

• Nonvolatile Instant-On Operation: Flash-based architecture retains configuration when power is removed, removing the need for external configuration memory.
• Balanced Mid-Range Capacity: 9,216 logic elements and 400,000 equivalent gates provide a practical density for many control, interface, and signal-processing designs.
• Flexible I/O Count and Voltage Support: 151 user I/Os and family-level mixed-voltage support allow direct interfacing with multiple voltage domains on the same board.
• Industrial-Grade Reliability: Rated for −40 °C to 100 °C operation, suitable for demanding environmental conditions common in industrial applications.
• Compact Surface-Mount Packaging: 208-pin BFQFP (208-PQFP, 28 × 28 mm) enables high-density PCB layouts while maintaining a wide I/O complement.
• Regulatory and Environmental Compliance: RoHS-compliant construction supports environmental and regulatory requirements.
