Product Summary

The MC68HC908JK3ECDW is a member of the low-cost, highperformance M68HC08 Family of 8-bit microcontroller units (MCUs). The MC68HC908JK3ECDW is based on the customer-specified integrated circuit (CSIC) design strategy. All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.
