A42MX36-3PQG208I

Overview

The A42MX36-3PQG208I is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 54,000 system gates and 2,438 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with supply ranges of 3V to 3.6V for the core and 4.75V to 5.25V for I/Os. It utilizes a 208-BFQFP package with 176 user-programmable I/O pins. Key performance metrics include a maximum clock frequency of 99 MHz and a CLB-maximum combinational delay of 2.1 ns. The component operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides high-density logic capacity suitable for consolidating multiple PALS, CPLDs, and FPGAs into a single chip.
• Supports mixed-voltage operation allowing flexible integration of 3.3V and 5.0V components on the same board.
• Features deterministic timing and up to 100% pin locking for precise signal routing control.
• Includes in-system diagnostic capabilities via Silicon Explorer II for verification.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Industrial and automotive embedded logic applications

Procurement Notes

Verify the specific suffix '3' against official datasheets to confirm the exact speed grade and commercial/industrial temperature rating. Confirm RoHS compliance status and check for End-of-Life notices or Production Change Notices regarding assembly site updates before finalizing procurement plans.

Selection Notes

Select this model when 54,000 system gates and 2,438 CLBs are required for complex logic consolidation. Ensure the design accommodates the 208-pin PQFP footprint and mixed-voltage power requirements. Compare against lower gate counts like the A42MX24 if resource utilization permits cost reduction.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, which are established as cost-effective solutions for replacing discrete logic. These devices bridge the gap between simple CPLDs and larger FPGAs, offering high performance at 5V operation levels.

Replacement Considerations

Direct substitutes within the same family include the A42MX36-2PQG208I and A42MX36-1PQG208B, which share identical pinouts and logic resources but differ in speed grades and operating temperature specifications.
