Procurement Notes

Verify the specific MMU suffix against official Microchip documentation to confirm package type and environmental ratings. Ensure compatibility with existing PCB footprints for the designated package style. Confirm that the selected revision matches the required firmware lock bits and memory configuration for the target application.

Selection Notes

Select this component for applications requiring low power consumption alongside moderate processing speed. Consider the ATtiny48 variant when 4KB Flash is sufficient; choose ATtiny88 if 8KB Flash or 512 bytes SRAM are needed. Evaluate the available I/O lines and peripheral requirements against the specific package pinout constraints.

Part Context

This device belongs to the ATtiny48/88 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares architectural similarities with other AVR devices but is optimized for cost-sensitive embedded applications. The MMU suffix indicates a specific surface-mount package variation within the broader ATtiny product line.
