A42MX16-1PLG84I

Overview

The A42MX16-1PLG84I is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive Family. It features 24,000 system gates and operates with a supply voltage range of 4.5 V to 5.5 V. The device utilizes a Plastic Quad Flatpack No-Lead (QFN) package with 84 pins. It supports industrial temperature operation ranging from -40°C to +85°C. Key specifications include 608 Logic Elements and up to 140 I/O pins depending on pin configuration.

Feature Summary

• Single-chip ASIC alternative for automotive applications
• Deterministic, user-controllable timing
• Supports up to 100% resource utilization and pin fixing

Applications

• Automotive logic consolidation
• High-speed controllers
• Peripheral bus interfaces

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance for some variants in this family. Confirm lead times directly with the manufacturer or authorized distributors, as standard delivery periods may vary. Ensure the specific suffix matches required thermal and electrical characteristics for the target application environment.

Selection Notes

Select this model for designs requiring deterministic timing and high pin-fixing capabilities within the MX family. Compare against other package options like PLCC or TQFP if board space constraints differ. Verify that the 5V core voltage aligns with the system power architecture before finalizing the component choice.

Part Context

This component belongs to the Microchip A42MX series, designed as cost-effective single-chip solutions. The series integrates logic previously implemented in multiple PALs, CPLDs, and FPGAs. It targets applications needing high performance while shortening development cycles through synthesis-friendly architecture.

Replacement Considerations

Check for updated suffixes indicating RoHS compliance or revised packaging. Consult official discontinuance notifications for legacy Actel parts. Verify functional equivalence with newer Microchip FPGA families if long-term availability is a primary concern.
