A40MX04-PQ100I

Overview

The A40MX04-PQ100I is a field-programmable gate array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 6000 system gates and 295 configurable logic blocks (CLBs). The device supports a maximum clock frequency of 48.24 MHz with a CLB delay of 3.72 ns. It operates within a supply voltage range of 4.75V to 5.25V or 3.0V to 3.6V. The component is housed in a 100-lead Plastic Quad Flat Package (PQFP) and supports 69 I/Os. It functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Non-volatile flash-based architecture enabling instant-on functionality without external configuration memory.
• Supports high-density logic implementation through 295 configurable logic blocks for complex digital designs.
• Integrated JTAG boundary scan capability for comprehensive board-level testing and debugging.

Applications

• Industrial control systems requiring reliable programmable logic.
• Automotive electronics applications operating under extended temperature conditions.
• Communication interface protocols and signal processing tasks.

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) as per official datasheets. Confirm package integrity upon receipt, as moisture sensitivity level 3 requires proper handling. Check for recent Product Change Notifications regarding assembly sites or software updates before finalizing procurement orders.

Selection Notes

Select this model when a non-volatile FPGA with instant-on capability is required for space-constrained designs. Compare pin counts against the A40MX04-PLG68I if fewer I/Os are sufficient. Ensure the 100-pin PQFP footprint matches the PCB layout constraints. Verify voltage requirements align with the 3.3V or 5V system rails.

Part Context

This part belongs to the Actel/Microchip MX family of flash FPGAs, which utilize non-volatile technology to eliminate the need for external configuration PROMs. The A40MX04 variant represents a mid-range density option within this lineage, balancing logic capacity with power efficiency for embedded applications.

Replacement Considerations

Direct pin-compatible substitutes include other variants in the A40MX04 series such as A40MX04-1PQG100I or A40MX04-2PQG100I, depending on speed grade requirements. Cross-referencing with older Actel part numbers may be necessary for legacy design migrations.
