Text: NEC ELECTRONICS I NC 72 Ü|bi4a75aS 0001014 0 | D MOS DIGITAL INTEGRATED CIRCUIT uPD1990AC SERIAL I/O CALENDAR & CLOCK CMOS LSI The /iPD1990AC is a CMOS integrated circuit having a clock function, which has been designed with the intent of connecting to microcomputer. This 1C counts independently the month, date, day of the week, hour, minute and second, and is able to have the output and input of these time data freely upon command from the microcomputer. By employing this 1C, the
