DESC RIPTI ON
The IlPD652 is a IlCOM-45 4-bit single chip microcomputer manufactured with a low-
power-consumption CMOS process, allowing use of a single +5V power supply. The
IlPD652 provides all of the hardware features of the IlCOM-45 family, and executes all
58 instructions of the IlCOM-45 instruction set.
