A40MX04-PLG68

Overview

The A40MX04-PLG68 is a field-programmable gate array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features approximately 6000 system gates and 547 logic elements, providing 57 input/output pins. The device operates within a supply voltage range of 3V to 3.6V or 4.75V to 5.25V. It is housed in a 68-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads, designed for surface-mount installation. The standard commercial temperature range extends from 0°C to 70°C.

Feature Summary

• Configurable logic architecture supporting complex digital design implementations
• Non-volatile configuration capability ensuring immediate operation upon power-up
• In-system programmability allowing field updates without removal from the board

Applications

• Industrial control systems requiring reliable programmable logic
• Communication interface adapters and protocol converters
• Test and measurement equipment signal processing

Procurement Notes

Verify the specific suffix against official datasheets to confirm voltage and temperature ratings. Confirm RoHS compliance status and moisture sensitivity level before procurement. Check for recent Product Change Notices regarding assembly sites or packaging modifications. Ensure compatibility with existing PCB footprints for the PLCC-68 package.

Selection Notes

Select this component when non-volatile FPGA functionality is required to eliminate external configuration memory. Compare logic element counts and I/O availability against alternative MX series devices like the A40MX02 or A42MX09. Verify that the PLCC-68 package dimensions fit the mechanical constraints of the target enclosure.

Part Context

This part belongs to the Actel MX family of SRAM-based FPGAs acquired by Microchip Technology. The MX series is characterized by its low power consumption and non-volatile configuration capabilities. It serves as a successor to earlier CPLD technologies, offering greater flexibility for evolving digital logic requirements in embedded applications.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other variants in the A40MX04 series with different suffixes indicating extended temperature ranges or voltage options. Cross-family migration requires careful review of logic resource availability and I/O mapping differences.
