A42MX24-PQ160

Overview

The A42MX24-PQ160 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative for automotive applications. It features 36,000 system gates and 912 Adaptive Logic Modules (ALMs). The device supports up to 2.5 kbits of configurable dual-port SRAM and includes fast wide-decode circuitry. It operates within a supply voltage range of 4.75 V to 5.25 V and is available in a 160-pin PQFP package with 125 I/Os. The standard commercial grade version supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Supports deterministic, user-controllable timing with up to 100% resource utilization and pin fixing.
• Includes unique in-system diagnostic capability via Silicon Explorer II technology.
• Features synthesis-friendly architecture that supports ASIC design methodologies.

Applications

• Automotive applications requiring single-chip ASIC alternatives
• Industrial control systems
• Consumer electronics

Procurement Notes

Verify the specific suffix of the part number carefully, as variants such as -3PQG160 or -2PQG160 indicate different speed grades. Confirm whether the required unit is industrial grade (-40°C to +85°C) or extended grade (-40°C to +125°C), as these affect availability and specifications. Check for end-of-life status, as many MX series devices are obsolete. Ensure RoHS compliance matches project requirements.

Selection Notes

Select the appropriate speed grade suffix based on timing requirements; for example, -3 denotes 3ns while -2 denotes 2ns. Compare logic density against the A42MX16 if fewer gates suffice. Verify package compatibility, noting that PQG160 refers to the plastic quad flatpack. Consider the A40MX series if lower gate counts are sufficient for the design complexity.

Part Context

This component belongs to the Microchip Actel MX FPGA family, originally developed by Actel before its acquisition by Microsemi and subsequently Microchip. These devices utilize flash-based non-volatile technology, allowing for instant-on functionality without external configuration memory. The family bridges the gap between discrete logic and complex ASICs, offering reprogrammability with low power consumption.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolescence of the MX family, direct pin-to-pin replacements may be limited. Designers should consult Microchip for current generation FPGA equivalents or evaluate third-party compatible devices with similar gate counts and I/O configurations.
