A40MX04-1PQ100I

Overview

The A40MX04-1PQ100I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features approximately 6,000 system gates and 547 Logic Elements. The device supports mixed-voltage operation with core voltages of 3.3V or 5V and I/O levels compatible with 3.3V or 5V standards. It is housed in a 100-pin PQFP package and offers up to 89 user-programmable I/O pins. Operating temperatures range from -40°C to +85°C for industrial applications.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration of 3.3V and 5V components within a single design.
• Provides deterministic timing through user-controllable pin locking capabilities for precise signal routing.
• Includes diagnostic verification capabilities via Silicon Explorer II for in-system testing.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interface implementations
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for any Product Change Notifications regarding packaging or manufacturing site updates.

Selection Notes

Select this component when a cost-effective FPGA solution replacing multiple PALs or CPLDs is required. Ensure the 100-pin PQFP footprint matches the PCB layout constraints. Verify that the available I/O count meets the interface requirements for the target application.

Part Context

This part belongs to the A40MX series, which provides high-performance programmable logic at standard voltage levels. It serves as a direct replacement for complex discrete logic circuits, consolidating functionality into a single chip to reduce board space and development time.

Replacement Considerations

Compatible variants include the A40MX02 and A40MX08 for different gate counts. Other packages in the same logical family include PLCC and TQFP options, such as the A40MX04-1PLG100 or A40MX04-1TQ100, depending on physical size constraints.
