Description
CXP84540/84548 CMOS 8-bit Single Chip Microcomputer Description The CXP84540/84548 is a CMOS 8-bit microcomputer integrating on a single chip an A/D converter, serial interface, timer/counter, time-base timer, capture timer/counter, PWM output and the like besides the basic configurations of 8-bit CPU, ROM, RAM and I/O port. The CXP84540/84548 also
