DESCRIPTION
The 4509 Group is a 4-bit single-chip microcomputer designed with
CMOS technology. Its CPU is that of the 4500 series using a simple,
high-speed instruction set. The computer is equipped with two 8-bit
timers (each timer has two reload registers), interrupts, 10-bit A/D
converter, Serial interface and oscillation circuit switch function.
