A42MX24-PQ208I

Overview

The A42MX24-PQ20I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 912 Logic Elements and approximately 36,000 system gates within a PQFP-208 package. The device supports mixed-voltage operation with a core voltage of 5V and I/O voltages ranging from 3.3V to 5V. Electrical specifications include a minimum supply voltage of 4.5V and a maximum of 5.5V. It offers 176 user-programmable I/O pins and operates across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides high-density logic capacity suitable for consolidating multiple PALs, CPLDs, and FPGAs into a single chip.
• Supports deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.
• Enables mixed-voltage operation allowing flexible interface integration with both 3.3V and 5V components.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Automotive applications requiring robust programmable logic

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm the specific suffix 'I' denotes the industrial temperature grade (-40°C to +85°C). Check for recent Product Change Notifications (PCN) regarding manufacturing site updates or assembly changes. Ensure compliance with RoHS directives relevant to the procurement region before finalizing orders.

Selection Notes

Select this model when 912 LEs and 176 I/Os are required in a PQFP-208 form factor. Compare against the A42MX24-PQ208A if commercial temperature range (0°C to +70°C) suffices. Consider the A42MX36 series if higher gate counts are needed. Verify that the 5V core voltage aligns with the target system power architecture.

Part Context

This component belongs to the Microchip MX FPGA family, which bridges the gap between complex programmable logic devices and full-scale FPGAs. The A42MX24 variant specifically targets automotive and industrial sectors needing reliable, low-power reconfigurable logic. It serves as a direct replacement for legacy discrete logic solutions in embedded control environments.

Replacement Considerations

Direct pin-compatible alternatives within the same package include other A42MX24 variants with different temperature grades. For upgraded capacity, the A42MX36 series offers increased resources in similar packages. Verify that any substitute maintains the required 5V core voltage and I/O compatibility.
