DESCRIPTION
The 4513/4514 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 serial I/O, four 8-bit timers (each timer has a reload
register), and 10-bit A-D converter.
The various microcomputers in the 4513/4514 Group include variations of the built-in memory type and package as shown in the
table below.
