A42MX36-FPQ208

Overview

The A42MX36-FPQ208 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, 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 includes up to 2.5 kbits of configurable dual-port SRAM and offers up to 202 user-programmable I/O pins. The component is housed in a 208-pin Fine-Pitch Quad Flat Package (FPQFP) and provides high-performance logic capabilities.

Feature Summary

• Single-chip solution integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Supports mixed-voltage operation allowing 5.0V or 3.3V core and I/O configurations
• Includes fast wide-decode circuitry for address decoding and peripheral bus interfaces
• Features deterministic, user-controllable timing with up to 100% resource utilization

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interface implementations
• DSP and co-processor functions
• ASIC replacement designs requiring high capacity

Procurement Notes

Verify current availability status as the MX family has faced discontinuation notices. Confirm RoHS compliance and specific suffix requirements against official Microchip documentation before procurement. Check for Product Change Notifications regarding assembly sites or software updates.

Selection Notes

Select this model for applications requiring 54,000 system gates in a QFP package. Ensure voltage levels match the 3.3V/5V mixed-mode capability. Compare pin counts and SRAM requirements against similar MX variants like the A42MX36-PQG208 if different packaging is preferred.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families. These devices are positioned as cost-effective solutions for consolidating complex logic designs. The family is known for providing high performance while shortening system design cycles through its flash-based technology.

Replacement Considerations
