A42MX24-PQG208A

Overview

The A42MX24-PQG208A is a Field Programmable Gate Array (FPGA) from the Microchip A42MX24 series, manufactured by Microchip Technology. It features 912 Logic Elements and 36,000 system gates 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 provides 176 I/O pins. It operates within an industrial temperature range of -40°C to +125°C. This component serves as a high-capacity single-chip ASIC alternative.

Feature Summary

• Provides high-capacity programmable logic suitable for replacing multiple discrete PALS, CPLDs, and FPGAs in a single chip solution.
• Supports mixed-voltage operation allowing flexible integration of 5.0V or 3.3V core and I/O configurations.
• Includes deterministic, user-controllable timing capabilities to simplify system design and verification.

Applications

• High-speed controllers
• Address decoding circuits
• Peripheral bus interfaces

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm that the specific part number matches the required package type and temperature grade. Check for recent Product Change Notifications regarding manufacturing site updates or end-of-life status before finalizing procurement plans.

Selection Notes

Select this model when a dense logic capacity with 36,000 system gates is required in a 208-pin plastic quad flat pack. Ensure the application environment supports the specified -40°C to +125°C operating range. Verify that the 176 available I/O pins meet the interface requirements of the target system design.

Part Context

This FPGA belongs to the broader A42MX family, which includes variants like the A42MX16 and A42MX36. These devices share common architectural features such as fast wide-decode circuitry and configurable dual-port SRAM. The A42MX24 specifically offers a mid-range gate count within this high-performance series.

Replacement Considerations

Direct substitutes include other members of the A42MX family, such as the A42MX16 or A42MX36, depending on whether lower or higher logic density is acceptable. Cross-family replacements require careful evaluation of pin compatibility and resource utilization differences.
