The CDP6805E2 Microprocessor Unit (MPU) belongs to the
CDP6805 Family of CMOS Microcomputers. This 8-blt fully
static and expandable microprocessor contains a CPU, on-
chip RAM, I/O, and Timer. It is a low-power, low-cost
processor designed for mid-range applications in the
consumer, automotive, Industrial, and communications
markets where very low power consumption constitutes an
Importantiactor. The following are the major features ofthe
CDP6805E2 MPU.
Software Features:
• Efficient use of program spece
• Versatile interrupt handling
• True bit manipulation
• Addressing modes with Indexed addressing for tables
• Efficient instruction set
• Memory mapped I/O
• Two power saving standby modes
