DESCRIPTION

The MC68HC05P6 is a member of the low-cost, high-performance M68HC05

Family of 8-bit microcontroller units (MCUs). The M68HC05 Family is based on

the customer-specified integrated circuit (CSIC) design strategy. AII MCUs in

the family use the popular M68HC05 central processor unit (CPU) and are

available with a variety of subsystems, memory sizes and types, and package

types.

On-chip memory of the MC68HC05P6 includes 176 bytes of user RAM and

4672 bytes of user ROM.
