CXP85460

CXP85452/85460 CMOS 8-bit Single Chip Microcomputer Description The CXP85452/85460 are a highly integrated microcomputers composed of a 8-bit CPU, ROM, RAM, and I/O ports. These chips feature many other highperformance circuits in a single-chip CMOS design, including 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, and watchdog timer. Futhermore, the CXP85452/85460 series provides power-on reset and sleep functions which enable to lower power consumption. 64 pin SDIP (PIastic) 64 pin QFP (PIastic) Structure Silicon gate CMOS IC Features A wide instruction set (213 instructions) which covers various types of data – 16-bit operation/multiplication and division/Boolean bit operation instructions Minimum instruction cycle 0.5µs at 8MHz Incorporated ROM capacity 52K bytes (CXP85452) 60K bytes (CXP85460) Incorporated RAM capacity 960 bytes Peripheral functions – A/D converter 8-bit, 4-channel successive approximation method (Conversion time of 20µs at 8MHz) – Serial interface 8-bit clock sync type, 1 channel – Timer 8-bit timer 8-bit timer/counter 19-bit time-base timer – On screen display (OSD) function 12 × 18 dots, 384 character types, 15 character colors, 12lines of 32 characters, black frame output/half blanking, shadow, background color on full screen/half blanking, double scanning, jitter elimination circuit – I2C bus interface – PWM outp...
