A42MX16-PQG208A

Overview

The A42MX16-PQG208A is a Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 24,000 system gates and 608 Logic Elements within a 208-pin PQFP package. The device supports mixed-voltage operation with supply ranges of 3V to 3.6V or 4.75V to 5.25V. It includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory functions. The component operates within a commercial temperature range of 0°C to 70°C and offers high performance with clock-to-out delays as low as 5.6 ns.

Feature Summary

• Provides high-density programmable logic with up to 202 user-programmable I/O pins for complex interface consolidation.
• Integrates configurable dual-port SRAM to support fast data buffering and FIFO applications.
• Supports mixed-voltage core and I/O operation, enabling compatibility with both 3.3V and 5.0V systems.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interfaces and DSP co-processor functions
• ASIC prototyping and replacement for multiple PALs, CPLDs, and FPGAs

Procurement Notes

Verify the specific suffix 'A' against official Microchip documentation to confirm it denotes the commercial temperature grade variant. Confirm current lifecycle status, as many MX series components are subject to discontinuation notices. Ensure the 208-PQFP package dimensions match the target PCB footprint requirements before finalizing procurement plans.

Selection Notes

Select this model when 24,000 system gates and 202 I/O pins are required in a 208-pin form factor. Compare against the A42MX36 if higher gate counts are needed. Verify that the 0°C to 70°C operating range meets environmental constraints, as industrial variants may require different suffixes. Check for available design tools compatible with the MX family architecture.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, which are positioned as cost-effective solutions for consolidating discrete logic. These devices are engineered to replace multiple legacy programmable logic chips, offering deterministic timing and high resource utilization for embedded control applications.
