A42MX24-PQ160M

Overview

The A42MX24-PQ160M is a non-volatile Field Programmable Gate Array (FPGA) from the Microchip MX Automotive family. It features 36,000 system gates and 912 logic elements within a 160-pin PQFP package. The device operates on a single 5V supply with a voltage range of 4.75V to 5.25V. It supports up to 125 I/O pins and includes configurable dual-port SRAM for embedded memory functions. Designed for automotive applications, it offers deterministic timing and in-system diagnostic capabilities via Silicon Explorer II.

Feature Summary

• Non-volatile architecture eliminates configuration overhead and reduces system power consumption by removing external configuration devices.
• Automotive-grade design ensures reliability and compliance with stringent environmental standards for vehicle electronics.
• Supports 100% pin fixing and resource utilization, facilitating direct ASIC replacement and simplified board layout.

Applications

• Automotive body control modules and lighting systems
• Instrument clusters and infotainment interfaces
• Industrial motor control and automation logic

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Request official traceability documentation and RoHS compliance certificates upon order. Confirm that the specific suffix matches the required temperature grade and package variant. Inspect packaging for moisture sensitivity indicators prior to soldering. Maintain proper ESD handling protocols during storage and assembly processes.

Selection Notes

Select this model when a 5V supply is required for the entire system. Ensure the 160-pin PQFP footprint aligns with the PCB design constraints. Verify that the 36,000 gate count meets the logic density requirements without excessive margin. Consider the operating temperature range specified for the target application environment. Check if the available I/O count satisfies all peripheral connection needs.

Part Context

This part belongs to the A42MX series, which provides high-density programmable logic with built-in non-volatile configuration. The MX family is specifically engineered to replace complex ASICs in cost-sensitive and high-reliability markets. It shares architectural similarities with other A42MX variants but differs in gate count and package options.

Replacement Considerations

Direct pin-to-pin replacements may include other A42MX24 variants with different packages, such as A42MX24-PQ208A or A42MX24-PL84A, provided the physical footprint allows modification. Verify electrical compatibility and timing specifications before substituting.
