A3P400-1PQG208I Overview

The Microchip Technology A3P400-1PQG208I is a ProASIC3 flash-based Field Programmable Gate Array (FPGA) delivering 400,000 system gates, 55,296 bits of RAM, and 151 user I/Os in a 208-pin PQFP (PQG208) package. It operates from a 1.5 V core supply and supports a wide range of I/O standards, making it a versatile single-chip solution for cost-sensitive, mid-density logic applications.

A Field Programmable Gate Array (FPGA) is an integrated circuit that can be configured by the customer after manufacturing, typically using a hardware description language (HDL) such as Verilog or VHDL. Unlike ASICs, FPGAs offer reprogrammability and faster time-to-market. The ProASIC3 family uses nonvolatile flash technology, providing instant-on operation, low power consumption, and enhanced security compared to SRAM-based FPGAs, which require external configuration memory.

The A3P400-1PQG208I features 4,500 logic elements (VersaTiles), 151 user I/Os, and 55,296 bits of embedded RAM. It supports up to 4 I/O banks with programmable voltage standards, including LVCMOS, LVTTL, PCI, and LVDS. The device also includes a PLL for clock management and supports in-system programming (ISP) via JTAG, enabling field updates. Its flash-based architecture provides inherent immunity to single-event upsets (SEU), making it suitable for mission-critical applications.

This FPGA is built on a 130 nm flash process, offering a balance of density, performance, and power. The -1 speed grade provides system performance up to 350 MHz for internal logic. The device is available in a 208-pin PQFP package with a 28x28 mm body and 0.5 mm pitch, suitable for surface-mount assembly. The flash configuration is nonvolatile, so the device powers up instantly without external boot memory, reducing BOM cost and board space.

Typical applications include industrial automation, motor control, communications infrastructure, and defense systems. Its low power and instant-on capability make it ideal for portable and battery-powered devices. The 151 I/Os allow flexible interfacing with sensors, ADCs, DACs, and communication transceivers. The embedded RAM can be used for FIFOs, buffers, or small lookup tables.

When designing with this device, ensure proper decoupling of the 1.5 V core supply and the VCCIBx bank supplies. Use the JTAG interface for programming and boundary-scan testing. The flash-based configuration is secure and does not require external memory, but consider the I/O bank voltage requirements to avoid damage. The device supports hot-swap and power-up sequencing per the datasheet guidelines.

Selection Guide

Choose the A3P400-1PQG208I when you need a mid-density FPGA with 400K gates, 151 I/Os, and flash-based instant-on capability. It is ideal for industrial, defense, and medical applications where reliability and security are paramount. If you require higher performance, select the A3P400-2PQG208I (faster speed grade). For higher density, the A3P600-1PQG208I offers more logic and RAM but at a higher cost. If your design fits within 250K gates, the A3P250-1PQG208I is a more cost-effective option. All alternatives are pin-compatible, allowing easy migration without PCB redesign.

Key Differentiators

  • Flash-based instant-on architecture (vs SRAM-based FPGAs (e.g., Xilinx Spartan-6))
  • Low power consumption (vs A3P600-1PQG208I)
  • Cost-effective density (vs A3P250-1PQG208I)

Design Notes

The A3P400-1PQG208I requires a 1.5V core supply and separate I/O bank supplies (VCCIBx). Use low-ESR ceramic capacitors (0.1uF and 10uF) close to each VCC and VCCIBx pin. The total core current can be estimated based on logic utilization and toggle rate; refer to the Microchip power calculator for accurate estimates. Ensure the power supply can handle transient currents during configuration and operation.

For the 208-pin PQFP package, use a 4-layer or more PCB with dedicated power and ground planes. Route I/O traces with controlled impedance if using high-speed interfaces like LVDS. Place decoupling capacitors as close as possible to the power pins. Follow the layout guidelines in the ProASIC3 datasheet to minimize noise and crosstalk. The exposed pad (if present) should be soldered to the ground plane for thermal and electrical performance.

A common mistake is connecting I/O bank supplies (VCCIBx) incorrectly. Each bank must be powered to the appropriate voltage for the I/O standard used. Also, ensure the JTAG pins (TCK, TDI, TDO, TMS) are properly terminated and not left floating. The device is flash-based, so no external configuration memory is needed, but verify the programming interface is correctly connected. Avoid exceeding the absolute maximum ratings on any pin.
