A42MX09-PQG160M

Overview

The A42MX09-PQG160M is a field-programmable gate array (FPGA) from the Microchip MX series, featuring 14,000 system gates and 336 logic elements. It provides 101 I/Os in a 160-pin PQFP package. The device operates on 3.3V or 5V supplies, with voltage ranges of 3.0V–3.6V and 4.75V–5.25V respectively. It supports an industrial temperature range of -40°C to +85°C. Key features include non-volatile flash configuration memory, SRAM-based reconfigurability, and support for JTAG debugging.

Feature Summary

• Non-volatile flash configuration memory eliminates external configuration devices.
• SRAM architecture allows for in-system reconfiguration and rapid prototyping.
• Integrated JTAG boundary scan support for manufacturing test and debugging.

Applications

• Industrial control systems requiring reliable logic processing.
• Automotive electronics applications needing robust performance.
• Communication interface adapters and protocol converters.

Procurement Notes

Verify the 'M' suffix indicates military-grade temperature rating (-40°C to +85°C). Confirm RoHS compliance status as some variants may differ. Check for obsolescence notices since the A42MX09 series has faced discontinuation announcements. Ensure the specific package variant matches design requirements.

Selection Notes

Compare against A42MX09-1PQG160 for commercial grade if lower cost is acceptable. Consider A42MX16 or A42MX24 for higher logic density needs. Verify voltage compatibility with existing 3.3V or 5V power rails. Ensure PCB layout accommodates the 160-PQFP footprint dimensions.

Part Context

Part of the Microsemi/Microchip Actel MX family, bridging CPLD and FPGA capabilities. Offers flash-based non-volatility unlike traditional SRAM FPGAs. Provides a balance of programmability and persistent configuration without external boot devices.

Replacement Considerations

Direct substitutes are limited due to series discontinuation. Evaluate A42MX16 or A42MX24 variants for pin-compatible upgrades with increased resources. Cross-reference with newer Microchip PolarFire or IGLOO2 families for long-term availability.
