A40MX04-PQ100A

Overview

The A40MX04-PQ100A is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip solution for high-performance logic applications. It features approximately 6,000 system gates and 547 Logic Elements within a 100-pin Plastic Quad Flat Package (PQFP). The device supports dual-voltage operation with core voltages of 3.3V or 5V and I/O levels compatible with both standards. It operates within a commercial temperature range of 0°C to +70°C and includes JTAG boundary scan support for testing.

Feature Summary

• Acts as a cost-effective single-chip alternative to multiple discrete PALs, CPLDs, and FPGAs by consolidating complex logic functions.
• Supports mixed-voltage operation allowing flexible integration of 3.3V and 5.0V I/O interfaces while maintaining PCI compliance.
• Provides deterministic timing with user-controllable resource utilization and pin locking capabilities for precise design implementation.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interface implementations
• Digital Signal Processing (DSP) and coprocessor functions

Procurement Notes

Verify the specific suffix 'A' against the official Microchip datasheet to confirm it denotes an industrial or extended temperature grade rather than the standard commercial variant. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the procurement channel provides valid traceability documentation for this legacy component series.

Selection Notes

Select this model when a compact 100-pin footprint is required for mid-density logic designs. Compare the 6,000 gate capacity against project requirements to ensure sufficient resources. Verify that the PQFP package style matches the PCB layout constraints and that the voltage domain requirements align with the available 3.3V or 5V supply rails.

Part Context

This component belongs to the Actel MX family, now manufactured under Microchip Technology following the acquisition of Actel Corporation. The 40MX series represents a generation of flash-based FPGAs known for instant-on capabilities and non-volatile configuration storage without external memory devices.

Replacement Considerations

Direct replacements include other variants within the A40MX04 series such as A40MX04-PLG68I for smaller packages or A40MX04-CQ100I for military-grade specifications. Cross-reference pinouts and electrical characteristics carefully when substituting with different package types or temperature grades.
