A42MX24-1PQG208M

Overview

The A42MX24-1PQG208M is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 36,000 system gates and up to 2.5 kbits of configurable dual-port SRAM. The device supports mixed-voltage operation with 5.0V or 3.3V core and I/Os, offering PCI-compliant interfaces. It provides up to 202 user-programmable I/O pins in a 208-pin PQFP package. Key performance metrics include a 5.6 ns clock-to-out delay, 250 MHz maximum performance, and 5 ns dual-port SRAM access time.

Feature Summary

• Single-chip solution integrating logic previously requiring multiple PALs, CPLDs, and FPGAs
• Deterministic, user-controllable timing for predictable system design
• Supports up to 100% resource utilization and 100% pin locking
• Includes unique in-system diagnostic capability via Silicon Explorer II

Applications

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

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status and check for Product Change Notices regarding assembly site updates or obsolescence schedules. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering.

Selection Notes

Select this model for designs requiring deterministic timing and high I/O density in a plastic package. Consider the -1 speed grade for specific timing constraints. Evaluate thermal management needs for the 208-PQFP form factor. Verify voltage domain compatibility if mixing 3.3V and 5.0V signals on I/Os.

Part Context

This part belongs to the 40MX and 42MX FPGA families, which offer gate counts ranging from 3,000 to 54,000. These devices are positioned as cost-effective alternatives to ASICs, bridging the gap between standard PLDs and complex FPGAs by providing high performance with shorter development cycles.

Replacement Considerations

Check for direct substitutes within the same MX family, such as the A42MX24-1PQG208B, noting any differences in speed grades or manufacturing revisions. Verify that any replacement maintains the 208-PQFP footprint and electrical characteristics.
