A42MX09-3PL84

Overview

The A42MX09-3PL84 is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive family, designed as a single-chip ASIC alternative for automotive applications. It features 9,000 system gates and 684 Configurable Logic Blocks (CLBs). The device supports dual voltage operation with supply ranges of 3V to 3.6V and 4.75V to 5.25V. It utilizes a PLCC-84 plastic package and operates within an industrial temperature range of 0°C to 70°C. Key architectural elements include fast wide-decode circuitry, synthesis-friendly logic, and up to 2.5 kbits of configurable dual-port SRAM.

Feature Summary

• Deterministic timing with user-controllable delays and unique in-system diagnostic capability via Silicon Explorer II
• Low power consumption design suitable for automotive environments
• IEEE Standard 1149.1 JTAG boundary scan testing and verification support

Applications

• Automotive electronic control units requiring ASIC replacement
• Industrial automation logic control systems
• Consumer electronics interface bridging
• Telecommunications signal processing modules

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels. Confirm RoHS compliance status and specific suffix variations against official datasheets prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage during assembly processes.

Selection Notes

Select this model when a fixed-function ASIC replacement is needed with FPGA reprogrammability. Verify that the 9,000 gate count and 84-pin I/O capacity meet system requirements. Ensure compatibility with 3.3V or 5V logic levels. Consider thermal management solutions appropriate for the PLCC-84 package within the specified operating temperature range.

Part Context

This component belongs to the Microchip MX family of FPGAs, originally developed by Actel before its acquisition by Microchip Technology. The series targets cost-sensitive applications requiring low power and high reliability. The A42MX09 variant specifically offers mid-range logic density within the automotive-grade portfolio.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to proprietary architecture. Evaluate functional equivalents from other vendors only if timing constraints and I/O configurations match exactly. Verify software toolchain compatibility if migrating from legacy Actel development environments.
