The MC68HC908MR8 is a member of the low-cost, high-performance
M68HC08 Family of 8-bit microcontroller units (MCU). The M68HC08
Family 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.
