A42MX24-PQG208M

Overview

The A42MX24-PQG208M is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It features 36,000 system gates and utilizes a 208-pin PQFP package. The device supports mixed-voltage operation with core and I/O voltages of either 5.0V or 3.3V, ensuring PCI compliance. Key performance metrics include a maximum clock frequency of 250 MHz, a 5.6 ns clock-to-out delay, and up to 2.5 kbits of configurable dual-port SRAM. It offers up to 202 user-programmable I/O pins and deterministic timing for complex logic consolidation.

Feature Summary

• High-capacity architecture serving as a single-chip ASIC alternative with up to 36,000 system gates.
• Mixed-voltage operation capability supporting both 5.0V and 3.3V core and I/O configurations.
• Integrated configurable dual-port SRAM for efficient data buffering and processing.
• Deterministic, user-controllable timing with fast wide-decode circuitry.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Consolidation of logic previously implemented in multiple PALs, CPLDs, and FPGAs

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to potential counterfeit risks. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your supply chain requirements. Ensure proper ESD handling procedures are followed during storage and installation to maintain device integrity.

Selection Notes

Select this model when a dense logic solution with mixed-voltage compatibility is required. Compare gate counts against similar MX family members if higher capacity is needed. Verify that the 208-pin PQFP package dimensions fit your PCB layout constraints. Consider thermal management requirements given the plastic package construction and operating temperature range.

Part Context

This component belongs to the Microchip 40MX and 42MX FPGA families, which provide cost-effective design solutions at 5V. These devices are engineered to shorten system design cycles by integrating and consolidating logic from multiple legacy programmable devices into a single chip.

Replacement Considerations

Direct substitutes within the same package may include other variants from the A42MX series such as A42MX16 or A42MX36, depending on specific gate density requirements. Cross-reference pinouts and voltage specifications carefully before substitution.
