A42MX16-FPLG84

Overview

The A42MX16-FPLG84 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 24,000 system gates and utilizes CMOS technology in an 84-pin PLCC package. The device supports dual voltage supplies: 3V to 3.6V and 4.5V to 5.5V. It includes configurable dual-port SRAM, fast wide-decode circuitry, and supports up to 100% resource utilization with deterministic timing. Operating temperatures range from -40°C to +125°C.

Feature Summary

• Single-chip ASIC alternative for automotive applications
• Deterministic, user-controllable timing
• Unique in-system diagnostic capability with Silicon Explorer II
• Low power consumption design

Applications

• Automotive electronics systems
• Industrial control embedded systems
• Bluetooth and IoT wireless terminals

Procurement Notes

Verify the specific suffix 'FPLG84' against official Microchip documentation, as standard listings often use 'PL84'. Confirm RoHS compliance status, as some variants are non-compliant. Check moisture sensitivity level (MSL 3) requirements for handling. Ensure the supplier provides valid traceability documents for automotive-grade components.

Selection Notes

Select this model for designs requiring 24,000 system gates in a compact PLCC-84 footprint. Compare I/O counts (72 available) against interface requirements. Consider the -40°C to +125°C temperature range for harsh environments. Evaluate if the 2.5 kbits of SRAM meets memory needs without external storage.

Part Context

Part of the A42MX series FPGAs, originally developed by Actel and acquired by Microchip. This series targets cost-sensitive automotive and industrial markets needing ASIC-like performance with FPGA flexibility. It serves as a drop-in replacement for complex discrete logic or small ASICs.

Replacement Considerations

Direct substitutes include other A42MX16 variants with different packages, such as A42MX16-PL84A or A42MX16-VQG100A. Cross-reference pinouts carefully when switching between PLCC and QFP packages. Verify software compatibility with current Microchip Libero SoC tools.
