A42MX24-PQG208A - 36K Gate MX FPGA, 176 I/O | Microchip
MPN： A42MX24-PQG208A ✓ 啟用中A42MX24-PQG208A 概覽
An FPGA is an integrated circuit that can be configured by the customer or designer after manufacturing—hence "field-programmable." FPGAs contain a fabric of programmable logic blocks and interconnects, allowing them to implement arbitrary digital logic functions. They sit between fixed-function ASICs and general-purpose processors, offering flexibility and parallel processing capabilities. The MX family is a mature, 5.0 V architecture optimized for high-volume applications where cost and reliability are paramount.
Key features of the A42MX24-PQG208A include 36,000 system gates, 912 logic modules, 176 user I/Os, and support for 5.0 V and 3.3 V mixed-voltage systems via MultiPlex I/Os. The device is fully compliant with the PCI Local Bus Specification (version 2.1), enabling direct interface to PCI buses without additional glue logic. It also features a low-power mode, making it suitable for power-sensitive designs.
Technically, the MX family uses a 0.45 µm process technology and supports system speeds up to 135 MHz. The device includes dedicated clock networks and programmable I/O standards, allowing flexible integration into various system architectures. The 208-pin PQFP package provides a compact footprint while offering ample I/O for medium-density logic designs.
Typical applications include industrial control, transportation systems, consumer electronics, and legacy PLD consolidation. The 5.0 V operation and PCI compliance make it ideal for interfacing with older 5 V logic families and PCI-based systems, while the low-power mode extends battery life in portable applications.
When designing with this FPGA, ensure proper decoupling of the 5.0 V supply and follow the manufacturer's layout guidelines for the PQFP package to minimize signal integrity issues. The device supports in-system programming, allowing firmware updates without removing the component from the PCB.

- Commercial temperature range (對比A42MX24-1PQG208M)
設計說明
The A42MX24-PQG208A operates from a 5.0 V supply. Ensure the power supply is stable and well-regulated, with adequate decoupling capacitors (0.1uF and 10uF) placed close to each VCC pin. The device supports mixed-voltage I/Os (3.3V and 5.0V), so verify that I/O banks are configured correctly to avoid damage. Estimated: total power consumption depends on logic utilization and toggle rate; refer to the datasheet's power estimation section for accurate calculations.
For the 208-pin PQFP package, follow the manufacturer's recommended land pattern and keep traces short to minimize parasitic inductance. Use a solid ground plane and separate analog/digital grounds if mixed-signal interfaces are used. Ensure proper solder paste stencil design for fine-pitch leads to avoid bridging. The package has a 28x28 mm body with 0.5 mm lead pitch, so precise PCB fabrication is essential.
The PQFP package has limited thermal dissipation capability. Estimated: at 5.0 V and typical current draw of 100 mA, power dissipation is 0.5 W. With a theta_JA of approximately 40 C/W (typical for PQFP), the junction temperature rise is 20C above ambient. For high-utilization designs, ensure adequate airflow or add a heatsink. The commercial temperature range (0C to +70C) must not be exceeded.
