A42MX09-1PLG84M

Overview

The A42MX09-1PLG84M is a flash-based Field Programmable Gate Array (FPGA) from the Microchip MX Automotive family. It features 14,000 system gates and 336 Logic Elements within a PLCC-84 package. The device supports mixed-voltage operation with core voltages of 3.3V or 5V and I/O voltages ranging from 4.75V to 5.25V. It operates within an industrial temperature range of -40°C to +85°C. Key specifications include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, and support for IEEE 1149.1 JTAG boundary scan testing.

Feature Summary

• Single-chip ASIC alternative offering deterministic timing and user-controllable delays for automotive applications.
• Supports up to 100% resource utilization and 100% pin locking for secure design implementation.
• Enables mixed-voltage operation allowing flexible integration of 3.3V and 5V I/O standards.
• Includes unique in-system diagnostic capability via Silicon Explorer II technology.

Applications

• Automotive electronic control units requiring single-chip ASIC replacement.
• Industrial systems needing deterministic timing and high reliability.
• Mixed-voltage interface logic bridging 3.3V and 5V domains.

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes military grade or specific packaging variations, as standard commercial variants typically use suffixes like 'A' or 'I'. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the supplier provides valid traceability documents for automotive-grade components.

Selection Notes

Select this component when designing for automotive environments requiring robust FPGA capabilities with fixed pin assignments. Compare gate density against the A40MX series for cost optimization. Verify that the PLCC-84 package fits the PCB footprint constraints. Ensure the design tool suite supports the MX architecture for proper synthesis and place-and-route.

Part Context

This part belongs to the Microchip MX Automotive FPGA family, originally developed by Actel before its acquisition by Microchip Technology. The A42MX09 variant specifically targets mid-range complexity applications within the 14K gate category. It serves as a drop-in replacement for complex discrete logic or older CPLDs in automotive and industrial sectors.

Replacement Considerations

Direct pin-compatible replacements may be found within the same A42MX09 series using different suffixes for temperature or package variations. For higher capacity needs, consider the A42MX24 series. Legacy Actel parts may require firmware migration tools provided by Microchip for configuration bitstream compatibility.
