CXP86212/86216, CXP86324/86332
CXP86440/86448/86460
CMOS 8-bit Single Chip Microcomputer
Description
The CXP86212/86216, CXP86324/86332, CXP86440/
86448/86460 are the CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time-base
timer, on-screen display function, I2C bus interface,
PWM output, remote control reception circuit, HSYNC
counter, watchdog timer, 32kHz timer/counter besides
the basic configurations of 8-bit CPU, ROM, RAM, I/O
ports.
The CXP86212/86216, CXP86324/86332, CXP86440/
86448/86460 also provide a SLEEP function that
enables to lower the power consumption.
