A42MX16-PQ100A

Overview

The A42MX16-PQ100A is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 100-pin Plastic Quad Flat Package (PQFP). It contains 295 Configurable Logic Blocks (CLBs) and offers approximately 2000 equivalent system gates. The device supports a maximum clock frequency of 48.24 MHz with a CLB delay of 3.72 ns. It operates within a temperature range of -55°C to +125°C and utilizes a 5V supply voltage.

Feature Summary

• Provides high-capacity single-chip ASIC alternative capabilities with up to 54,000 system gates across the family.
• Features fast wide-decode circuitry and deterministic, user-controllable timing for precise design implementation.
• Supports mixed-voltage operation for core and I/Os, including PCI-compliant interfaces.

Applications

• High-speed controllers
• Address decoding logic
• Peripheral bus interfaces

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for PQFP-100 assemblies. Confirm moisture sensitivity level requirements during storage and handling procedures prior to soldering.

Selection Notes

Select this model for designs requiring moderate logic density with robust industrial or military temperature ratings. Compare CLB counts and I/O availability against other MX series variants to ensure optimal resource utilization. Verify that the 5V operating voltage aligns with the target system power rails.

Part Context

This component belongs to the Microsemi (now Microchip Technology) 40MX and 42MX FPGA families. These devices are designed as cost-effective solutions for consolidating logic previously implemented in multiple PALs, CPLDs, or FPGs into a single chip.

Replacement Considerations

Check for direct pin-compatible alternatives within the same MX family, such as the A42MX16-2PQ100A, which shares similar specifications but may differ in speed grade or specific performance metrics.
