A42MX16-1PQG100M

Overview

The A42MX16-1PQG100M is a field-programmable gate array (FPGA) from the Microchip MX family, housed in a 100-pin plastic quad flat package (PQFP). It provides 295 configurable logic blocks and approximately 2,000 system gates. The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V. Maximum clock frequency is rated at 48.24 MHz, with a CLB delay of 3.72 ns. Operating temperature ranges extend to -55°C for military variants.

Feature Summary

• Single-chip ASIC alternative integrating high-capacity logic
• Configurable dual-port SRAM up to 2.5 kbits
• Mixed-voltage operation supporting 3.3V and 5.0V I/Os
• Deterministic user-controllable timing

Applications

• High-speed controllers
• Address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the suffix 'M' against official datasheets to confirm if it denotes military grade or specific packaging. Check moisture sensitivity level and reflow soldering profiles before assembly. Confirm RoHS compliance status for the specific revision.

Selection Notes

Compare CLB count and gate density against application requirements. Ensure voltage levels match system constraints. Verify package dimensions and pinout compatibility with existing PCB layouts.

Part Context

Part of the 40MX and 42MX FPGA families offering cost-effective design solutions. Consolidates logic from multiple PALs, CPLDs, and FPGAs into a single chip.

Replacement Considerations

Check for direct substitutes within the A42MX16 series with different suffixes for temperature or package variations. Verify functional equivalence before substitution.
