1 / 66 page  Document No. IC-2763B (O. D. No. IC-7628D) Date Published November 1993 P Printed in Japan © NEC Corporation 1990 DATA SHEET MOS INTEGRATED CIRCUIT µPD75328 4-BIT SINGLE-CHIP MICROCOMPUTER The mark 5 shows the major revised points. DESCRIPTION The µPD75328 is one of the 75X Series 4-bit single-chip microcomputer, and has a data processing capability comparable to that of an 8-bit microcomputer. In addition to high-speed operation with 0.95 µs minimum instruction execution time for the CPU, the µPD75328 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 controller/driver and A/D converter, its data processing capability is the highest in its class in the world. The µPD75P328 with one-time PROM, which is replaced with the internal mask ROM for a µPD75328, is applicable for evaluating systems under development, or for small-scale production of developed systems. "Detailed functions are described in the following user's manual. Be sure to read it for designing." " µPD75328 User's Manual: IEM-5045" FEATURES • Capable of high-speed operation and variable instruction execution time to power save • 0.95 µs, 1.91 µs, 15.3 µs (Main system clock: operating at 4.19 MHz) • 122 µs (Subsystem clock: operating at 32.768 kHz) • 75X architecture comparable to that for an 8-bit microcomputer is employed • Built-in programmable LCD controller/driver • Built-in 8-bit resolution A/D converter: 6 channels • Clock operation at reduced power dissipation: 5 µA TYP. (operating at 3 V) • Timer function: 3 channels • Interrupt functions especially enhanced for applications, such as remote control receiver • Pull-up resistors can be provided for 35 I/O lines • Built-in NEC standard serial bus interface (SBI) APPLICATIONS Cameras, blood pressure gauges, airconditioners, etc. The information in this document is subject to change without notice. ORDERING INFORMATION Part Number Package Quality Grade µPD75328GC-xxx-3B9 80-pin plastic QFP (s s14mm) Standard Remarks: xxx is ROM code number. Please refer to “Quality Grade on NEC Semiconductor Devices” (Document Number IEI-1209) published by NEC Corporation to know the specification of quality grade on the devices and its recommended applications. |
