A42MX36-1CQ256B

Overview

The A42MX36-1CQ256B is a Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features approximately 36,000 system gates and 2,438 Configurable Logic Blocks (CLBs). The device provides 202 I/O pins within a 256-pin Thin Quad Flat Package (TQFP). It operates on dual voltage supplies: 3V to 3.6V for core logic and 4.75V to 5.25V for I/O interfaces. The component supports non-volatile Flash configuration, eliminating the need for external configuration memory.

Feature Summary

• Integrates non-volatile Flash technology for instant-on operation without external configuration devices.
• Supports high-density logic implementation with over 2,400 configurable logic blocks.
• Provides extensive I/O connectivity suitable for complex interface requirements.

Applications

• Industrial control systems requiring robust programmable logic
• Automotive electronics applications demanding reliability
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix 'B' against official Microchip documentation to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status and check for Product Change Notifications regarding assembly sites or material updates before finalizing procurement plans.

Selection Notes

Select this model when a high gate count FPGA with integrated Flash configuration is required in a TQFP form factor. Ensure the design accommodates the specified dual voltage supply requirements for both core and I/O domains. Verify that the 256-pin package fits the available PCB real estate constraints.

Part Context

This component belongs to the Microchip A42MX family of Flash FPGAs, which are designed for cost-sensitive and space-constrained applications. The MX series is known for combining SRAM-like flexibility with Flash non-volatility, offering a middle ground between standard SRAM FPGAs and complex CPLDs.

Replacement Considerations

Check for direct cross-references within the A42MX36 family with different package options such as PQFP or CQFP variants. Consider the A42MX24 or A42MX16 if lower gate counts suffice, though pinouts may differ significantly.
