A42MX16-3PLG84

Overview

The A42MX16-3PLG84 is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive Family. It features 24,000 system gates and 608 Adaptive Logic Modules (ALMs). The device operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range of -40°C to +125°C. It is housed in an 84-pin Plastic Leaded Chip Carrier (PLCC) package with 72 available I/Os. Key architectural elements include fast wide-decode circuitry and support for up to 100% resource utilization.

Feature Summary

• Designed as a single-chip ASIC alternative for automotive applications
• Supports deterministic, user-controllable timing with unique in-system diagnostic capability
• Features synthesis-friendly architecture compatible with ASIC design methodologies

Applications

• Automotive electronic control units
• Industrial motor control systems
• High-reliability logic replacement circuits

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.

Selection Notes

Select this model when automotive-grade reliability (-40°C to +125°C) and high gate density are required. Compare pin counts and I/O configurations against similar PLCC packages if board space is constrained. Verify that the 5V operating voltage aligns with existing system power rails before finalizing the design.

Part Context

This component belongs to the Microchip MX family, which bridges the gap between complex CPLDs and high-end FPGAs. The series is specifically engineered for cost-sensitive, high-volume automotive and industrial markets requiring robust programmable logic solutions.

Replacement Considerations

Direct substitutes may include other variants within the A42MX16 series with different speed grades or package types, such as A42MX16-PQG100A. Cross-reference pinouts and electrical specifications carefully when considering alternatives from other manufacturers.
