A42MX24-1PQ208M

Overview

The A42MX24-1PQ208M is a Field Programmable Gate Array (FPGA) from the Microchip Technology A42MX series. It features 912 Logic Elements and approximately 36,000 system gates within a 208-pin PQFP package. The device operates at a supply voltage of 5V, with a range of 4.5V to 5.5V. It supports an industrial temperature range from -40°C to +125°C and includes up to 2.5 kbits of configurable dual-port SRAM. The component offers 176 user-programmable I/O pins and utilizes flash-based non-volatile technology for instant-on functionality.

Feature Summary

• Flash-based architecture providing non-volatile configuration and instant-on capability without external memory.
• Supports mixed-voltage operation allowing 5.0V or 3.3V core and I/O configurations.
• Includes fast wide-decode circuitry and deterministic, user-controllable timing characteristics.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interfaces and DSP co-processor functions
• Industrial automation and automotive control systems

Procurement Notes

Verify the specific suffix 'M' against official documentation to confirm material composition or environmental compliance status. Check current lifecycle status as many variants in this family are subject to discontinuation notices. Confirm moisture sensitivity level requirements for surface-mount assembly processes.

Selection Notes

Select this model when a 5V supply is required for both core and I/Os. Compare logic density against the A42MX16 if fewer resources suffice. Ensure the 208-pin PQFP footprint matches the target PCB design constraints. Verify that the 176 available I/O pins meet the interface requirements.

Part Context

This component belongs to the Actel MX family, originally developed by Actel Corporation and acquired by Microsemi, now part of Microchip Technology. The A42MX series is designed as a high-capacity single-chip ASIC alternative, consolidating logic previously implemented in multiple PALs, CPLDs, and FPGs into a single flash-based device.

Replacement Considerations

Direct pin-compatible replacements may include other variants within the A42MX24 family, such as the A42MX24-PQ208A or A42MX24-PQG208M, depending on the required temperature grade and speed bin. Verify functional equivalence before substitution.
