A3P250-PQ208 - 250K Gate ProASIC3 FPGA | Microchip
MPN: A3P250-PQ208 ✓ AktifA3P250-PQ208 Ringkasan
An FPGA (Field-Programmable Gate Array) is an integrated circuit that can be configured by the customer after manufacturing to implement arbitrary digital logic functions. FPGAs belong to the programmable logic device (PLD) hierarchy, sitting above CPLDs in density and capability, and are used to prototype or implement digital systems without the cost and lead time of custom ASICs. The ProASIC3 family is a flash-based FPGA, meaning configuration is stored in non-volatile flash cells, providing instant-on operation, low power, and inherent security against reverse engineering.
Key features of the A3P250-PQ208 include 6144 configurable logic blocks (CLBs), 151 user I/O pins, and 36,864 bits of RAM. The device supports a maximum clock frequency of 350 MHz and is offered in a 208-pin PQFP package, which is a surface-mount package with gull-wing leads on all four sides. The flash-based architecture eliminates the need for external configuration memory, simplifying board design and reducing total cost of ownership.
Technically, the ProASIC3 core tile can be configured as either a three-input lookup table (LUT) equivalent or a D-flip-flop/latch with enable, a unique VersaTile capability that allows efficient use of the FPGA fabric. The device operates over a supply voltage range of 1.425 V to 1.575 V, with a nominal 1.5 V, and is available in both commercial and industrial temperature grades. The 130 nm process technology balances performance and power, making it suitable for a wide range of applications.
Typical applications include industrial automation, automotive electronics, communications infrastructure, and consumer electronics. The A3P250-PQ208 is particularly well-suited for glue logic, bus interfacing, and control applications where its instant-on capability and security features are advantageous. Its 151 I/O pins provide ample connectivity for interfacing with microcontrollers, sensors, and other peripherals.
When designing with this device, ensure that all power supply pins are properly decoupled with 0.1 uF and 10 uF capacitors, and follow the layout guidelines in the Microchip ProASIC3 handbook to minimize noise and ensure reliable operation. The flash-based configuration is non-volatile, so no external boot device is required, but careful attention to power sequencing is recommended.

Diferensiator Kunci
- Flash-based configuration provides instant-on and security (vsSRAM-based FPGAs (e.g., Xilinx Spartan-6))
- Low power consumption due to 130 nm flash process (vsA3P400-FG256I)
- Pin-compatible with lower-density ProASIC3 devices (vsA3P125-PQ208 and A3P060-PQ208)
Catatan Desain
The A3P250-PQ208 requires a 1.5 V core supply (1.425 V to 1.575 V). Use a low-dropout regulator or a switching regulator with low ripple to provide this rail. Decouple each VCC pin with a 0.1 uF ceramic capacitor placed as close to the pin as possible, and add a 10 uF bulk capacitor at the power entry point. Ensure the power supply can handle the device's peak current, which depends on the design's logic utilization and I/O activity. Refer to the Microchip ProASIC3 power estimation spreadsheet for accurate current requirements.
For the 208-pin PQFP package with 0.500 mm pitch, use a PCB with fine-pitch layout capabilities. Ensure that the PCB footprint matches the recommended land pattern in the Microchip datasheet. Provide adequate ground planes for both core and I/O supplies. Route high-speed signals with controlled impedance if needed. Place decoupling capacitors on the bottom side of the PCB directly under the VCC pins to minimize loop area. Follow the layout guidelines in the ProASIC3 handbook to reduce noise and ensure reliable operation.
The A3P250-PQ208's power dissipation depends on logic utilization, clock frequency, and I/O loading. For typical designs, the junction temperature should be kept below 125°C. The PQFP package has a thermal resistance (theta_JA) that varies with airflow and PCB copper area. Estimated: For a design dissipating 1 W with theta_JA of 30°C/W, the junction temperature rise is 30°C above ambient. Ensure adequate airflow or a heatsink for high-power designs. Refer to the Microchip thermal application note for detailed thermal modeling.
