SECTION 1
INTRODUCTION
1.1 GENERAL
The CDP68HC05C4 HCMOS Microcomputer is a member of the CDP68HC05 Family of
low-cost single-chip microcomputers. This 8-bit microcomputer contains an on-chip
oscillator, CPU, RAM, ROM, 1/0, two serial interface systems, and timer. The fully static
design allows operation at frequencies down to dc, further reducing its already low-power
consumption.
The CDP68HC05C8 Microcomputer (MCU) device is similar to the CDP68HC05C4 MCU
with one exception. This exception incorporates 3584 additional bytes of user ROM for a
total of 7744 bytes of on-chip user ROM. All information on the CDP68HC05C4 MCU
applies to the CDP68HC05C8 MCU with the exception of the memory description.
