A42MX24-PQ208

Overview

The A42MX24-PQ208 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 36,000 system gates and 912 Logic Elements within a PQFP-208 package. The device supports mixed-voltage operation with a supply voltage range of 4.5 V to 5.5 V and offers up to 176 user-programmable I/O pins. It includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory functions. The architecture provides deterministic timing and supports high-performance applications requiring fast wide-decode circuitry.

Feature Summary

• Single-chip solution integrating logic previously implemented in multiple PALs, CPLDs, and FPGAs
• Supports mixed-voltage operation for both core and I/Os with PCI-compliant interfaces
• Provides deterministic, user-controllable timing for precise design implementation
• Includes unique in-system diagnostic capability using Silicon Explorer II technology

Applications

• High-speed controllers and peripheral bus interfaces
• DSP and co-processor functions
• Address decoding and logic consolidation

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm lot traceability and check for moisture sensitivity level compliance prior to assembly. Review official Product Change Notifications (PCN) for any manufacturing site updates or material changes that may affect long-term availability or performance specifications.

Selection Notes

Select this model when a dense logic capacity with 36,000 gates is required in a 208-pin surface-mount package. Ensure the design utilizes the 4.5 V to 5.5 V supply range and requires mixed-voltage I/O compatibility. Consider the PQFP-208 form factor for board space constraints while verifying thermal management requirements for the specified operating temperature range.

Part Context

This component belongs to the Microchip 40MX and 42MX FPGA families, which are engineered for cost-effective high-performance designs. These devices consolidate complex logic into a single chip, reducing system size and development cycles. The MX series is widely recognized for its synthesis-friendly architecture and support for standard ASIC design methodologies.

Replacement Considerations

Compatible alternatives within the same family include the A42MX16 and A42MX36 variants, offering different gate densities. Verify pin-to-pin compatibility and logic resource sufficiency before substitution. Consult official datasheets for specific electrical parameter differences between density grades.
