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.
