A42MX09-PL84

Overview

The A42MX09-PL84 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in an 84-pin PLCC package. It features 684 Configurable Logic Blocks (CLBs) and 9,000 system gates. The device operates at a supply voltage range of 4.5 V to 5.25 V, with a maximum clock frequency of 96 MHz and a CLB combinatorial delay of 2.1 ns. It supports mixed-voltage I/O operation at 3.3 V or 5.0 V and includes up to 2.5 kbits of configurable dual-port SRAM.

Feature Summary

• Single-chip ASIC alternative offering high performance and resource consolidation
• Mixed-voltage operation supporting both 3.3V and 5.0V core and I/O levels
• Deterministic, user-controllable timing for precise design integration
• In-system diagnostic capability utilizing Silicon Explorer II technology

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status as historical Actel data may vary. Check for End-of-Life notifications or discontinuance notices prior to procurement. Ensure the supplier provides valid traceability for the component origin.

Selection Notes

Select this model for designs requiring 9,000 system gates in a compact PLCC-84 footprint. Verify that the 96 MHz speed grade meets the target application's timing requirements. Consider the mixed-voltage I/O capabilities if interfacing with different logic families. Evaluate the available 2.5 kbits of SRAM against memory needs.

Part Context

This component belongs to the Microchip MX FPGA family, originally developed by Actel. The series is designed as a cost-effective solution for replacing multiple PALs, CPLDs, and FPGAs on a single chip. The A42MX09 variant specifically targets applications needing moderate logic density with deterministic timing characteristics.
