A42MX16-1PQG208M

Overview

The A42MX16-1PQG208M is a Field Programmable Gate Array (FPGA) belonging to the Microsemi 40MX and 42MX families. It features 295 Configurable Logic Blocks (CLBs) and approximately 2,000 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 voltage range of 3.0 V to 3.6 V and functions across an industrial temperature range of -40°C to +85°C. The component is housed in a 100-pin Plastic Quad Flat Package (PQFP).

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs.
• Supports mixed-voltage operation for core and I/Os, including PCI-compliant interfaces.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking.

Applications

• High-speed controllers and address decoding systems.
• Peripheral bus interface implementations.
• DSP and co-processor function integration.

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes a military-grade qualification or specific environmental rating, as standard commercial variants typically use suffixes like 'I'. Confirm package integrity and moisture sensitivity level prior to assembly.

Selection Notes

Select this component when replacing legacy discrete logic or lower-density PLDs with a need for higher density and mixed-voltage compatibility. Ensure the design requires the specific gate count and I/O availability of the 42MX family rather than newer low-power architectures.

Part Context

This part belongs to the Microsemi 40MX/42MX FPGA family, designed as high-capacity single-chip solutions. These devices consolidate complex logic designs into a single chip, offering performance comparable to ASICs while maintaining the flexibility of programmable logic for rapid development cycles.

Replacement Considerations

Direct substitutes include other members of the 42MX family such as the A42MX16-PQG208A or A42MX16-CQ100I, provided pinout and electrical specifications match the application requirements.
