UPD75316A

DATA SHEET MOS INTEGRATED CIRCUIT µPD75312(A), 75316(A) 4-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD75316(A) is one of the 75X Series 4-bit single-chip microcomputer having a built-in LCD controller/ driver, and has a data processing capability comparable to that of an 8-bit microcomputer. In addition to high-speed operation with 0.95 µ s minimum instruction execution time for the CPU, the µ PD75316(A) can also process data in 1-, 4-, and 8-bit units. Therefore, as a 4-bit single-chip microcomputer chip having a built-in LCD panel controller/driver, its data processing capability is the highest in its class in the world. Detailed functions are described in the following user's manual. Be sure to read it for designing. µ PD75308 User's Manual: IEM-5016 FEATURES Higher reliability than µPD75316 Internal memory Program memory (ROM) : 16256 × 8 bits (µ PD75316(A)) : 12160 × 8 bits (µ PD75312(A)) Data memory : 512 × 4 bits Capable of high-speed operation and variable instruction execution time to power save 0.95 µs, 1.91 µs, 15.3 µs (operating at 4.19 MHz) 122 µs (operating at 32.768 kHz) 75X architecture comparable to that for an 8-bit microcomputer is employed Built-in programmable LCD controller/driver Clock operation at reduced power dissipation: 5 µA TYP. (operating at 3 V) Enhanced timer function (3 channels) Interrupt functions especially enhanced for applications, such as remote control receiver Pull-up resistors can be provided for 31...
