A42MX16-PLG84I

Overview

The A42MX16-PLG84I is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive Family. It provides 24,000 system gates and supports mixed-voltage operation at 3.3V or 5.0V for core and I/Os. The device features up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. It operates within an industrial temperature range of -40°C to +85°C and utilizes an 84-pin PLCC package with 72 user-programmable I/O pins.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, and FPGAs
• Supports deterministic, user-controllable timing with up to 100% resource utilization and pin fixing
• Includes unique in-system diagnostic capability via Silicon Explorer II
• Compatible with IEEE Standard 1149.1 JTAG boundary scan testing

Applications

• Automotive applications as a single-chip ASIC alternative
• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify RoHS compliance status carefully, as specific suffixes in this family may indicate non-compliance. Confirm the exact package type and temperature grade against the manufacturer's current datasheet before procurement, as availability and environmental certifications can vary by production batch.

Selection Notes

Select this model for designs requiring 24,000 system gates with mixed 3.3V/5V I/O capabilities. Ensure the design fits within the 72 available I/O pins and 2.5 kbits SRAM limit. Verify that the PLCC package form factor matches the PCB footprint requirements and that the -40°C to +85°C operating range meets the application's thermal constraints.

Part Context

This component belongs to the Microchip MX Automotive Family of FPGAs, which offers cost-effective solutions for consolidating complex logic. The series ranges from 3,000 to 54,000 system gates, providing high performance while shortening development cycles compared to discrete logic implementations.

Replacement Considerations

Check for direct substitutes within the A42MX16 series with different packages, such as A42MX16-PQG100I or A42MX16-2TQG176I, if pin compatibility allows. Verify functional equivalence regarding gate count and SRAM capacity when considering cross-package replacements.
