A3P400-PQG208I - ProASIC3 FPGA, 400K Gates | Microchip
MPN: A3P400-PQG208I ✓ 啟用中A3P400-PQG208I 概覽
A Field Programmable Gate Array (FPGA) is an integrated circuit that can be configured by the customer after manufacturing, allowing rapid prototyping and flexible hardware design. FPGAs sit within the broader category of programmable logic devices (PLDs), which also includes CPLDs and SoC FPGAs. The ProASIC3 family is a flash-based FPGA, meaning configuration is stored in non-volatile flash memory, enabling instant-on operation without an external boot device.
Key features of the A3P400-PQG208I include 400,000 system gates, 55,296 bits of RAM, 151 user I/Os, and a system performance of up to 231 MHz. The device supports multiple I/O standards and features four I/O banks with dedicated VCCIBx supplies. Its flash-based architecture provides inherent security against reverse engineering and supports single-chip, low total cost of ownership (TOC) designs.
The ProASIC3 architecture uses a flash-based switch matrix that is reprogrammable and retains configuration when power is removed. This eliminates the need for external configuration memory, reducing board space and BOM cost. The device also includes an abundance of advanced features such as clock conditioning circuits (CCC) and phase-locked loops (PLLs) for robust clock management.
Typical applications include industrial control, automotive electronics, communications infrastructure, and consumer electronics where low power, instant-on, and security are critical. The 208-pin BFQFP package with 0.5 mm pitch provides a compact footprint suitable for space-constrained designs.
When designing with this device, ensure proper decoupling of the 1.5 V core supply and each VCCIBx bank supply. The four I/O banks allow mixing of different I/O voltage standards, but only compatible standards can be assigned to the same bank. Refer to the ProASIC3 migration application note for guidance on migrating between densities.

主要差異化特點
- Industrial temperature range (對比A3P400-PQG208)
- Flash-based instant-on configuration (對比SRAM-based FPGAs)
- Inherent security (對比SRAM-based FPGAs)
設計說明
The A3P400-PQG208I requires a 1.5 V core supply (1.425 V to 1.575 V) and separate I/O bank supplies (VCCIBx) for each of the four I/O banks. Use low-impedance decoupling capacitors (0.1 uF and 10 uF) close to each VCC and VCCIBx pin. The core current draw depends on logic utilization and toggle rate; estimate power using Microchip's power calculator. Ensure the power supply can handle peak inrush current during configuration.
The 208-BFQFP package has a 0.5 mm pitch, requiring careful PCB layout. Use a 4-layer or more board with dedicated power and ground planes. Route I/O traces with controlled impedance if using high-speed interfaces. Place decoupling capacitors as close as possible to the power pins. Follow Microchip's layout guidelines for the ProASIC3 family to minimize noise and ensure reliable operation.
A common pitfall is assigning incompatible I/O voltage standards to the same I/O bank. The four I/O banks have dedicated VCCIBx supplies, so only I/Os with compatible voltage standards can be assigned to the same bank. Refer to the ProASIC3 migration application note for guidance. Also, ensure the core supply is within 1.425 V to 1.575 V; exceeding this range can damage the device.
