1.3 Features
Technical Data
The MC68HC05K1 and MC68HC05K0 are members of Motorola’s
low-cost, high-performance M68HC05 Family of 8-bit microcontroller
units (MCU). The M68HC05 Family is based on the customer-specified
integrated circuit (CSIC) design strategy. All 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 includes 504 bytes of user read-only memory (ROM)
and 32 bytes of user random-access memory (RAM).
The MC68HC05K1 has an additional 64-bit personality, erasable,
programmable, read-only memory (PEPROM). In an MC68HC05K1
MCU, the PEPROM cannot be erased and serves as a 64-bit array of
one-time programmable ROM (OTPROM).
