A42MX24-1PQ208

Overview

The A42MX24-1PQ208 is a Field Programmable Gate Array (FPGA) from the Microchip Technology A42MX24 series. It features 912 Logic Elements and 36,000 system gates within a 208-pin PQFP package. The device supports mixed-voltage operation with a supply voltage range of 4.5 V to 5.5 V. It operates within an industrial temperature range of -40°C to +125°C. The component includes up to 2.5 kbits of configurable dual-port SRAM and offers 176 user-programmable I/O pins. Designed as a single-chip ASIC alternative, it integrates fast wide-decode circuitry and deterministic timing for high-performance logic applications.

• Deterministic, user-controllable timing with up to 100% resource utilization
• In-system diagnostic capability via Silicon Explorer II

Applications

• High-speed controllers
• Address decoding
• Peripheral bus interfaces
• DSP functions
• Co-processor functions

Procurement Notes

Verify current availability status as the A42MX24 series may be subject to discontinuation notices. Confirm RoHS compliance and moisture sensitivity levels prior to procurement. Ensure compatibility with existing design tools and programming cables. Check for specific ordering suffixes that define temperature grades or package variations. Validate lead times through authorized distributors given potential end-of-life constraints.

Selection Notes

Select this model for designs requiring 36,000 system gates in a 208-pin PQFP footprint. Choose based on the need for industrial temperature ratings (-40°C to +125°C). Consider the 176 I/O count for interface density requirements. Verify power supply constraints align with the 4.5V to 5.5V operating range. Evaluate if the integrated SRAM meets memory needs without external components.

Part Context

This component belongs to the Actel MX family, now under Microchip Technology. The A42MX series is known for non-volatile flash-based FPGA technology. It serves as a drop-in replacement for complex programmable logic devices. The family emphasizes low power consumption and high reliability for automotive and industrial sectors.

Replacement Considerations

Direct pin-to-pin replacements are limited due to specific gate counts and package types. Review the A42MX36 series for higher capacity options in similar packages. Consider the A40MX series for legacy compatibility if lower performance is acceptable. Consult Microchip documentation for recommended migration paths from obsolete parts.
