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)

* Pull-up resistors (RP) must be connected to SDA0 (or SDA1) and SCL0 (or SCL1). * Serial resistance (Rs = 300 or less) of SDA0 (or SDA1) and SCL0 (or SCL1) reduces spike noise caused by CRT flash-over.
