A42MX16-1PQG208

Overview

The A42MX16-1PQG208 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 16,000 system gates and 352 Configurable Logic Blocks (CLBs). The device includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory functions. It supports mixed-voltage operation with I/Os compatible with 5.0V or 3.3V standards. The component is housed in a 208-pin PQFP package and offers deterministic timing with user-controllable constraints.

Feature Summary

• Provides high-density logic consolidation replacing multiple PALs, CPLDs, and FPGAs on a single chip.
• Supports mixed-voltage operation allowing integration of 5.0V and 3.3V core and I/O domains.
• Enables 100% resource utilization and pin locking for precise layout control.
• Includes unique in-system diagnostic capabilities via Silicon Explorer II.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Complex logic replacement in industrial and automotive environments

Procurement Notes

Verify the specific suffix '1' against official datasheets to confirm it denotes the commercial temperature grade (-40°C to +85°C). Confirm RoHS compliance status and check for Product Change Notifications regarding assembly sites or software updates before finalizing procurement plans.

Selection Notes

Select this model when requiring approximately 16,000 system gates with significant embedded SRAM capacity. Ensure the design utilizes the 208-pin PQFP footprint. Verify that the required I/O voltage levels align with the mixed-voltage support specifications provided in the electrical characteristics section.

Part Context

This part belongs to the Microchip 42MX family, which succeeded the 40MX line. These devices are characterized by fast wide-decode circuitry and high performance suitable for complex digital logic applications. The family bridges the gap between simple PLDs and larger FPGAs.

Replacement Considerations

Direct replacements within the same package include other variants of the A42MX16 series. For higher density requirements, consider the A42MX24 or A42MX36 models, ensuring pin compatibility and thermal limits are met.
