CXP843P40

CXP843P40 CMOS 8-bit Single Chip Microcomputer Description The CXP843P40 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, and remote control reception circuit besides the basic configurations of 8-bit CPU, ROM, RAM, and I/O port. The CXP843P40 also provides a sleep/stop function that enables lower power consumption. This IC is the PROM-incorporated version of the CXP84340 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. 80 pin QFP (Plastic) Structure Silicon gate CMOS IC Features Wide-range instruction system (213 instructions) to cover various types of data — 16-bit arithmetic/multiplication and division/boolean bit operation instructions Minimum instruction cycle 400ns at 10MHz operation 122µs at 32kHz operation Incorporated PROM capacity 40K bytes Incorporated RAM capacity 1120 bytes Peripheral functions — A/D converter 8 bits, 8 channels, successive approximation method (Conversion time of 32µs/10MHz) — Serial interface Incorporated 8-bit, 8-stage FIFO (Auto transfer for 1 to 8 bytes), 1 channel 8-bit clock synchronization, 1 channel — Timer 8-bit timer 8-bit timer/counter 19-bit time base timer 16-bit capture timer/counter 32kHz timer/counter — Remote control reception circuit 8-bit ...
