A42MX16-1PLG84

Overview

The A42MX16-1PLG84 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 supports mixed-voltage operation with supply voltages of 3V to 3.6V or 4.5V to 5.5V. The device utilizes an 84-pin PLCC package and operates within a temperature range of -55°C to 125°C. Key specifications include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, and deterministic timing capabilities.

Feature Summary

• Supports mixed-voltage operation for core and I/Os with PCI-compliant interfaces
• Enables up to 100% resource utilization and 100% pin locking
• Provides deterministic, user-controllable timing for precise design integration
• Includes unique in-system diagnostic capability with Silicon Explorer II

Applications

• Automotive applications requiring single-chip ASIC alternatives
• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions

Procurement Notes

Verify RoHS compliance status carefully, as specific suffixes like '1' often indicate non-RoHS versions. Confirm lead times directly with authorized distributors, as availability varies by region. Ensure the ordering suffix matches the required voltage and temperature grade specifications exactly before placing orders.

Selection Notes

Select this component when designing for harsh environments requiring military-grade temperature ranges (-55°C to 125°C). Compare gate counts against similar MX family members if higher logic density is needed. Verify that the 84-pin PLCC package fits the target PCB footprint constraints and that the mixed-voltage requirements align with the system's power rails.

Part Context

This part belongs to the Microchip MX FPGA family, which bridges the gap between complex FPGAs and simple programmable logic devices. The series is notable for its high performance at 5V and support for both commercial and automotive sectors. It consolidates logic previously implemented in multiple PALs, CPLDs, and FPGAs into a single chip.

Replacement Considerations

Direct replacements within the same package may include other variants from the A42MX16 series with different suffixes indicating voltage or temperature grades. For higher capacity needs, consider the A42MX24 series. Always verify pin compatibility and timing characteristics when substituting.
