SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
REJ03B0008-0200Z Rev.2.00 2003.04.15
DESCRIPTION
The 4518 Group is a 4-bit single-chip microcomputer designed with C M O S technology. Its CPU is that of the 4500 series using a simple, high-speed instruction set. The computer is equipped with serial I/O, four 8-bit timers (each timer has one or two reload register), a 10-bit A-D converter, interrupts, and oscillation circuit switch function. The various microcomputers in the 4518 Group include variations of the built-in memory size as shown in the table below.
