A40MX04-PQG100M

Overview

The A40MX04-PQG100M is a field-programmable gate array from the Microchip Technology MX family, housed in a 100-pin PQFP package. It provides 547 logic elements and approximately 6,000 system gates. The device supports dual voltage operation with a core supply of 3.3V and I/O levels compatible with 5.0V standards. It operates within a commercial temperature range of 0°C to +70°C and includes JTAG boundary scan support for testing.

Feature Summary

• Single-chip FPGA architecture serving as an alternative to multiple discrete PALs or CPLDs
• Mixed-voltage capability allowing independent configuration of core and I/O voltages
• Supports deterministic timing with user-controllable pin locking and resource utilization

Applications

• High-speed controller implementations
• Peripheral bus interface logic
• Address decoding circuits

Procurement Notes

Verify the specific suffix 'M' against the manufacturer's current datasheet to confirm if it denotes a military-grade variant or standard commercial grade, as suffix definitions can vary by production era. Ensure the 100-pin PQFP footprint matches the target PCB design constraints before ordering.

Selection Notes

Select this component when a moderate logic density of roughly 6K gates is required in a plastic quad flat pack format. It is suitable for designs needing mixed 3.3V and 5V I/O compatibility without external level shifters. Consider the 0°C to +70°C operating range limits its use in harsh industrial environments.

Part Context

This part belongs to the Actel (now Microchip) 40MX series, which utilizes flash-based non-volatile technology. This allows for instant power-up configuration without external memory devices, distinguishing it from SRAM-based FPGAs that require boot programming.

Replacement Considerations

Direct replacements include other variants within the A40MX04 series such as A40MX04-1PQG100 or A40MX04-3PQG100, provided the temperature grade and speed bin requirements are met. Cross-family migration to A42MX models requires schematic and code adaptation.
