This document describes the TMP47C662/862 series of CMOS 4-bit single chip microcomputers. These devices are based on the TLCS-470 series architecture and include extended I/O parts, an A/D converter, a programmable pulse generator, and high breakdown voltage outputs.
The datasheet details the hardware configuration, pin assignments, and operational descriptions of the peripheral functions. Key features include 15 I/O ports (55 pins total), two 12-bit timers/counters, a watchdog timer, serial interface with simultaneous transmission/reception, and an 8-bit successive approximate A/D converter.
