CXP846P48

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. 80 pin QFP (Plastic) Structure Silicon gate CMOS IC Features Wide range instruction system (213 instructions) to cover various of data. — 16-bit arithmetic/multiplication and division/Boolean bit operation instructions Minimum instruction cycle 250ns at 16MHz operation (4.5 to 5.5V) 333ns at 12MHz operation (3.0 to 5.5V) 122µs at 32kHz operation (2.7 to 5.5V) Incorporated PROM capacity 48K bytes Incorporated RAM capacity 2048 bytes Peripheral functions — A/D converter 8 bits, 8 channels, successive approximation method (Conversion time 20µs/16MHz) — Serial interface Srart-stop synchronization (UART), 1 channel Incorporated buffer RAM (Auto transfer for 1 to 32 bytes), 1 channel Incorporated 8-bit, 10-stage FIFO (A...
