A42MX36-PQG208M

Overview

The A42MX36-PQG208M is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 54,000 system gates and 1,184 Logic Elements, housed in a PQFP-208 surface-mount package. The device supports mixed-voltage operation with a core voltage of 3.3 V and I/O levels compatible with 5 V systems. It operates within an extended industrial temperature range of -55°C to +125°C and includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications.

Feature Summary

• Provides high-density logic capacity suitable for consolidating multiple complex programmable logic devices into a single chip solution.
• Supports mixed-voltage operation allowing flexible interface integration between 3.3 V and 5 V system components.
• Includes configurable dual-port SRAM to facilitate data buffering and FIFO implementations without external memory.
• Offers deterministic timing characteristics with user-controllable pin locking for precise signal routing.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interfaces and DSP co-processor functions
• Military and aerospace avionics systems requiring wide temperature tolerance

Procurement Notes

This component has reached End-of-Life status, with official discontinuation notices indicating that manufacturing will cease. Verification of remaining stock or last-time buy windows is required before procurement planning. Engineers should review Product Change Notices for final availability dates and transition timelines to ensure supply continuity for existing production lines.

Selection Notes

Select this part when designing systems requiring 54K system gates with mixed 3.3V/5V I/O compatibility in a PQFP-208 package. Verify that the target application fits within the 1,184 Logic Element limit and requires the specified -55°C to +125°C operating range. Consider the EOL status and evaluate migration paths to newer FPGA families if long-term supply stability is a critical project constraint.

Part Context

The A42MX36 belongs to the Actel MX family, originally developed by Actel Corporation and later acquired by Microsemi, now part of Microchip Technology. This series is known for non-volatile flash-based FPGA technology, which eliminates the need for external configuration memory. The PQG208 suffix denotes the specific plastic quad flatpack package variant with 208 pins, optimized for surface-mount assembly in compact electronic designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the component's End-of-Life status. Designers should consult Microchip's official obsolescence management resources or contact authorized distributors for recommended next-generation replacements within the current portfolio.
