CXP834P16
CXP834P17
CMOS 8-bit Single Chip Microcomputer
Description
The CXP834P16 and CXP834P17 are a CMOS
8-bit microcomputer which consists of A/D converter,
serial interface, timer/counter, time base timer,
32kHz timer/counter, LCD controller/driver, remote
control receiving circuit and PWM output, as well as
basic configurations like 8-bit CPU, PROM, RAM
and I/O port. They are integrated into a single chip.
Also CXP834P16 and CXP834P17 provide sleep/
stop function which enables to lower power
consumption.
The CXP834P16 and CXP834P17 are the PROMincorporated version of the CXP83416 and
CXP83417 with built-in mask ROM. These provide
the additional feature of being able to write directly
into the program. Thus, they are most suitable for
evaluation use during system development and for
small-quantity production.
