CXP829P60
CMOS 8-bit Single Chip Microcomputer
Description
The CXP829P60 is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, fluorescent display panel controller/driver, I2C
bus interface, remote control transmission circuit,
remote control reception circuit, and 32kHz
timer/counter besides the basic configurations of 8-bit
CPU, PROM, RAM, and I/O port.
This LSI also provides sleep/stop functions which
enable to lower power consumption.
The CXP829P60 is the PROM-incorporated version
of the CXP82960 with built-in mask ROM, and it is
able to write directly into the program. Thus, it is most
suitable for evaluation use during system
development and for small-quantity production.

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