A40MX04-1PLG68M

Overview

The A40MX04-1PLG68M is a non-volatile FlashFPGA from the Microchip MX series, manufactured by Microchip Technology. It features 547 logic elements and approximately 6000 system gates within a 68-pin PLCC (J-Lead) surface-mount package. The device supports dual voltage operation at 3V to 3.6V and 4.75V to 5.25V, with an industrial operating temperature range of 0°C to 70°C. It includes 57 I/O pins and utilizes Flash technology for instant-on configuration without external memory.

Feature Summary

• Instant-on capability due to embedded non-volatile Flash configuration storage
• Supports both 3.3V and 5V supply voltages for flexible interface compatibility
• High pin count density with 57 I/Os in a compact 68-pin PLCC package

Applications

• Industrial control systems requiring reliable power-up states
• Embedded logic replacement for complex discrete gate designs
• Communication interface adapters and protocol converters

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation, as standard listings often use 'I' for industrial grade or no suffix for commercial grade. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements during handling. Check for recent Product Change Notifications regarding assembly sites or packaging updates before finalizing procurement orders.

Selection Notes

Select this component when instant-on functionality is critical to avoid external configuration EEPROMs. Compare against the A40MX04-1PLG68I if extended temperature ranges (-40°C to 85°C) are required instead of the standard 0°C to 70°C range. Ensure the 68-PLCC footprint matches the PCB design constraints compared to other package options like VQFP or PQFP.

Part Context

This part belongs to the A40MX04 family of FlashFPGAs, which integrates SRAM-based FPGA fabric with non-volatile Flash memory. This architecture eliminates the need for booting from external devices, reducing system complexity and board space. The MX series is designed for cost-sensitive applications requiring moderate logic density and high reliability.

Replacement Considerations

Direct substitutes include A40MX04-1PLG68 (commercial grade) or A40MX04-1PLG68I (industrial grade). Verify that the pinout and electrical characteristics remain identical across these variants before swapping.
