A42MX16-PL84M

Overview

The A42MX16-PL84M is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive Family. It features 24,000 system gates and operates within a supply voltage range of 3V to 3.6V or 4.5V to 5.5V. The device utilizes an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-Lead configuration. It supports surface mount installation and functions across a temperature range of -55°C to 125°C. Key architectural elements include configurable dual-port SRAM, fast wide-decode circuitry, and support for IEEE Standard 1149.1 JTAG boundary scan testing.

Procurement Notes

Verify RoHS compliance status carefully as specific suffixes may indicate non-compliant variants. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure the ordering suffix matches the required package type and temperature grade. Cross-reference the manufacturer part number against official Microchip databases to confirm current production status and availability of design tools.

Selection Notes

Select this component when a robust FPGA solution with automotive-grade reliability is required. Compare gate counts and I/O availability against other MX family members like the A42MX24 if higher density is needed. Verify that the PLCC package fits the PCB footprint constraints. Consider the operating voltage requirements to ensure compatibility with the target system's power rails.

Part Context

This device belongs to the Microchip MX Automotive Family of FPGAs, which bridges the gap between discrete logic and custom ASICs. The family offers scalable gate counts ranging from 3,000 to 54,000 system gates. These devices are engineered to replace complex ASIC designs in automotive and industrial environments, providing flexibility during development and final deployment phases.

Replacement Considerations

Direct substitutes within the same package and pinout include other A42MX16 variants such as A42MX16-PLG84M or A42MX16-PQG100I if package changes are acceptable. For higher capacity needs, consider the A42MX24 series. Always verify electrical characteristics and pin assignments before swapping components.
