A42MX16-PQG100M

Overview

The A42MX16-PQG100M is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a PQFP-100 package. It provides 295 Configurable Logic Blocks (CLBs) and approximately 2000 equivalent system gates. The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V. Key electrical parameters include a maximum clock frequency of 48.24 MHz and a CLB module delay of 3.72 ns. It operates within a temperature range of -55°C to +125°C and features up to 2.5 kbits of configurable dual-port SRAM.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os at 3.3V or 5.0V levels.
• Includes up to 2.5 kbits of configurable dual-port SRAM for data storage.
• Offers deterministic, user-controllable timing for precise signal management.
• Provides unique in-system diagnostic and verification capabilities.

Applications

• High-speed controllers
• Address decoding circuits
• Peripheral bus interfaces
• DSP functions

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes military-grade qualification or a specific packaging variant distinct from standard commercial versions. Ensure compatibility with existing PCB footprints for the PQFP-100 form factor. Confirm moisture sensitivity level requirements during assembly processes.

Selection Notes

Select this component when a single-chip ASIC alternative is required for logic consolidation. It serves as a replacement for multiple PALs, CPLDs, or FPGAs. Consider the 295 CLB capacity and 2000 gate count for moderate complexity designs requiring mixed-voltage I/O support.

Part Context

This part belongs to the Microsemi (now Microchip Technology) 40MX and 42MX FPGA families. These devices are designed to offer high performance while shortening system design cycles. The family includes various packages and speed grades, with the A42MX16 specifically targeting applications needing up to 24,000 system gates.

Replacement Considerations

Compatible variants within the same package include A42MX16-PQG100A. Verify pinout and voltage specifications before substitution. Other family members like A42MX16-VQG100M share similar logical resources but differ in package type.
