A42MX09-1PL84M

Overview

The A42MX09-1PL84M is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative for automotive and industrial applications. It features 14,000 system gates and 336 Logic Elements (LEs). The device supports mixed-voltage operation with core voltages of 3V to 3.6V and I/O voltages of 4.75V to 5.25V. It is housed in an 84-pin PLCC package and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Single-chip solution consolidating logic previously implemented in multiple PALs, CPLDs, and FPGAs.
• Supports up to 100% resource utilization and 100% pin locking for deterministic timing.
• Includes unique in-system diagnostic capability via Silicon Explorer II technology.

Applications

• Automotive embedded control systems
• High-speed controllers and address decoding
• Peripheral bus interfaces and DSP co-processor functions

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels. Confirm RoHS compliance status and check for Product Change Notifications (PCNs) regarding assembly site changes or obsolescence notices prior to procurement. Ensure supply chain documentation matches the specific suffix requirements for military-grade qualification if applicable.

Selection Notes

Select this model for designs requiring robust performance in harsh environments due to its extended temperature range. Consider the 14,000 gate capacity for moderate complexity logic. Verify that the 84-pin PLCC package fits the PCB footprint constraints. Evaluate power consumption against the 3.3V and 5V operating modes to ensure thermal management compatibility.

Part Context

This part belongs to the Microsemi (now Microchip) 42MX family, which bridges the gap between standard FPGAs and custom ASICs. The series is notable for its non-volatile SRAM-based architecture, allowing instant-on functionality without external configuration memory. The '1' suffix typically denotes the industrial/automotive temperature grade, while 'M' indicates military qualification options.

Replacement Considerations

Direct replacements are limited due to the specific MX architecture. Potential alternatives include other Microchip Actel FPGA families such as the A3P series, though pin counts and gate densities will differ significantly. Cross-referencing with Lattice or Altera devices requires careful evaluation of timing constraints and I/O voltage levels.
