Microcontrollers Procurement Notes

Verify the specific manufacturer designation, as this part may be listed under NXP USA Inc. following corporate acquisitions. Confirm the exact suffix 'ECDWER' matches the required package and temperature grade. Check current availability status as older HC08 series components may have limited stock or obsolescence notices.

Microcontrollers Selection Notes

Select this component when an 8-bit architecture with integrated FLASH and minimal peripheral requirements is needed. Ensure the design accommodates the 2.7V to 3.3V operating voltage. Verify that the 20-pin SOIC footprint fits the PCB layout constraints compared to alternative pin counts in the same family.

Microcontrollers Part Context

This MCU belongs to the MC908/JL3E family, designed for cost-sensitive applications requiring reliable 8-bit processing. It utilizes SuperFlash technology for endurance. The JL3E variant specifically targets compact designs with moderate I/O needs, balancing performance and power consumption for basic automation tasks.

Microcontrollers Replacement Considerations

Check for direct cross-references within the MC908KL3E or MC908KK3E families if pin compatibility allows. Verify if the MC68HC908JL3E datasheet specifies equivalent electrical characteristics for any legacy replacements.
