CXP845P60 CMOS 8-bit Single Chip Microcomputer Description The CXP845P60 is a CMOS 8-bit microcomputer integrating on a single chip an A/D converter, serial interface, timer/counter, time base timer, capture timer/counter, PWM output and the like besides the basic configurations of 8-bit CPU, PROM, RAM and I/O port. The CXP845P60 also provides a sleep/stop functions that enable to execute the power-on reset function or lower the power consumption. The CXP845P60 is the PROM-incorporated version of the CXP84548 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) 80 pin LQFP (Plastic) Features • A wide instruction set (213 instructions) which covers various types of data — 16-bit arithmetic/multiplication and division/Boolean bit operation instructions • Minimum instruction cycle 143ns at 28MHz operation (4.5 to 5.5V) 200ns at 20kHz operation (3.0 to 5.5V) • Incorporated PROM capacity 60K bytes • Incorporated RAM capacity 1472 bytes • Peripheral functions — A/D converter 8 bits, 8 channels, successive approximation method (Conversion time of 1.93µs at 28MHz, 2.7µs at 20MHz) — Serial interface Incorporated 8-bit, 8-stage FIFO (Auto transfer for 1 to 8 bytes, latch output function, MSB/LSB first selectable), 1 channel 8-bit clock sync type, 1 channel — Timer 8-bit timer 8-bit timer/counter 19-bit time base timer 16-bit capture time/counter — PWM output 8 bits, 2 channels • Interruption 14 factors, 14 vectors, multi-interruption possible • Standby mode Sleep/stop • Package 80-pin plastic QFP/LQFP Structure Silicon gate CMOS IC Sony reserves the right to change products and specifications without prior notice.
