MC908AP64CFBE Description
The MC908AP64CFBE is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). 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.The M68HC08 CPU (central processor unit) is an enhanced and fully object-code-compatible version ofthe M68HC05 CPU. The CPU08 Reference Manual (Freescale document order number CPU08RM/AD)contains a description of the CPU instruction set, addressing modes, and architecture.
