A42MX09-2PLG84I

Overview

The A42MX09-2PLG84I is a Field Programmable Gate Array from the Microchip MX Automotive Family. It features 14,000 system gates and 336 Logic Elements within a PLCC-84 package. The device operates on a supply voltage range of 4.75 V to 5.25 V, with a maximum clock frequency of 70.2 MHz. It supports mixed-voltage I/O operation at 3.3 V or 5.0 V. The component is rated for an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Single-chip ASIC alternative providing high performance and design cycle reduction
• Supports up to 100% resource utilization and 100% pin locking
• Includes unique in-system diagnostic capability with Silicon Explorer II
• Features deterministic, user-controllable timing

Applications

• Automotive applications as a single-chip ASIC alternative
• High-speed controllers and address decoding
• Peripheral bus interfaces and DSP functions

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) compared to commercial variants. Confirm RoHS compliance status through official Microchip documentation, as some MX family listings show conflicting data. Ensure the PLCC-84 package matches the target PCB footprint requirements before ordering.

Selection Notes

Select this model when 14,000 system gates are sufficient for the logic density requirement. The PLCC-84 package is suitable for surface-mount assembly where leaded plastic ceramic quad pack form factors are preferred. Verify that the 5V core voltage aligns with the system power architecture, as mixed-voltage I/O options exist for 3.3V compatibility.

Part Context

This part belongs to the A42MX series, which offers 3,000 to 54,000 system gates. The series is designed to consolidate logic previously implemented in multiple PALs, CPLDs, and FPGAs. It provides configurable dual-port SRAM and fast wide-decode circuitry for efficient integration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other A42MX09 variants such as A42MX09-PLG84A if package compatibility allows, but verify electrical and thermal specifications carefully.
