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. 1.2 FEATURES The following are some of the hardware and software highlights of these HCMOS Microcomputers.
