A42MX09-2PL84I

Overview

The A42MX09-2PL84I is a 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 operates on a single 5V supply voltage with a range of 4.75V to 5.25V. It supports up to 72 user-programmable I/O pins and includes configurable dual-port SRAM. 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 consolidation
• Deterministic, user-controllable timing with up to 100% resource utilization
• Supports mixed-voltage operation with PCI-compliant I/Os
• Includes unique in-system diagnostic capability via Silicon Explorer II

Applications

• Automotive applications requiring single-chip ASIC alternatives
• High-speed controllers and address decoding
• Peripheral bus interfaces and DSP functions

Procurement Notes

Verify the specific suffix '2' indicates the industrial temperature grade (-40°C to +85°C) and 'PL84' denotes the Plastic Leaded Chip Carrier package. Confirm RoHS compliance status as some variants in this family may be non-compliant. Check for End-of-Life notifications or discontinuance notices, as older MX series parts often face obsolescence. Ensure the supplier provides valid traceability documentation for automotive-grade components.

Selection Notes

Select this model when a 5V-only supply is required for the core and I/Os. Compare against the A42MX09-2PG100A if more I/O pins are needed, or the A42MX09-PLG84A for commercial temperature ranges. Verify that the 14,000 gate capacity meets the logic density requirements. Ensure the PLCC-84 footprint fits the PCB layout constraints compared to TQFP or VQFP options.

Part Context

This part belongs to the Microsemi/Microchip 40MX and 42MX FPGA families. These devices are designed as cost-effective solutions for replacing multiple PALs, CPLDs, and FPGAs. The family offers high performance with clock-to-out times as low as 5.6 ns and supports up to 2.5 kbits of configurable dual-port SRAM.
