CXP846P48
CMOS 8-bit Single Chip Microcomputer
Description
The CXP846P48 is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, capture timer/counter, I²C bus interface, remote
control reception circuit, PWM output, and 32kHz
timer/counter besides the basic configurations of 8-bit
CPU, PROM, RAM, and I/O port.
The CXP846P48 also provides a sleep/stop function
that enables lower power consumption.
The CXP846P48 is the PROM-incorporated version
of the CXP846P48 with built-in mask ROM. This
provides the additional feature of being able to write
directly into the program, Thus, it is most suitable for
evaluation use during system development and for
small-quantity production.
