A42MX24-3PQ160

Overview

The A42MX24-3PQ160 is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive family, designed as a single-chip ASIC alternative for automotive applications. It features 36,000 system gates and 912 logic elements within a PQFP-160 package. The device supports mixed-voltage operation with a core voltage of 3.3V and I/O voltages up to 5.0V, operating within a supply range of 4.75V to 5.25V. It includes up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. The component offers deterministic timing, 100% resource utilization, and pin fixing capabilities, along with IEEE 1149.1 JTAG boundary scan testing support.

Feature Summary

• Single-chip ASIC alternative architecture supporting up to 100% resource utilization and pin locking
• Mixed-voltage operation capability allowing 5.0V or 3.3V core and I/O configurations
• Integrated in-system diagnostic and verification capability via Silicon Explorer II
• Supports deterministic, user-controllable timing for precise design integration

Applications

• Automotive electronic systems requiring single-chip ASIC alternatives
• Industrial control applications utilizing mixed-voltage interfaces
• Designs requiring deterministic timing and high resource utilization

Procurement Notes

Verify the exact suffix against official Microchip documentation, as standard listings often use PQG160 for the plastic quad flatpack variant. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors, as legacy MX series parts may have specific environmental declarations. Ensure the selected speed grade matches the required system clock frequency for the target application.

Selection Notes

Select this FPGA when a solution bridging discrete logic and ASIC functionality is required for automotive or industrial environments. Consider the 36K gate capacity and available SRAM for complex state machines. Verify that the PQFP-160 package fits the PCB layout constraints and that the 5V tolerant I/Os align with the system bus requirements without additional level shifting.

Part Context

This component belongs to the Microchip MX family of FPGAs, which are engineered to replace complex discrete logic circuits. The family provides a flexible platform for prototyping and low-to-medium volume production, offering features like non-volatile configuration and robust automotive-grade reliability options.

Replacement Considerations

Direct replacements include other variants within the A42MX24 series such as A42MX24-PQG160 or A42MX24-2PQG160I, depending on the required speed grade. Cross-reference package types carefully, as PQFP and TQFP variants may differ in pin counts or thermal characteristics.
