D12320VF25IV Datasheet, PDF (7/1304 Pages) Renesas Technology Corp – Old Company Name in Catalogs and Other Documents

Preface
This LSI is a single-chip microcomputer made up of the H8S/2000 CPU with an internal 32-bit
architecture as its core, and the peripheral functions required to configure a system.
This LSI is equipped with ROM, RAM, a bus controller, data transfer controller (DTC), a 16-bit
timer pulse unit (TPU), a watchdog timer (WDT), a serial communication interface (SCI), DMA
controller (DMAC), a D/A converter, an A/D converter, and I/O ports as on-chip supporting
modules. This LSI is suitable for use as an embedded processor for high-level control systems. Its
on-chip ROM are flash memory (F-ZTAT™*) and mask ROM that provides flexibility as it can
be reprogrammed in no time to cope with all situations from the early stages of mass production to
full-scale mass production. This is particularly applicable to application devices with
specifications that will most probably change.
Note: * F-ZTAT is a trademark of Renesas Technology Corp.
Target Users: This manual was written for users who will be using the H8S/2329 Group,
H8S/2328 Group in the design of application systems. Members of this audience are
expected to understand the fundamentals of electrical circuits, logical circuits, and
microcomputers.
Objective:
This manual was written to explain the hardware functions and electrical
characteristics of the H8S/2329 Group, H8S/2328 Group to the above audience.
Refer to the H8S/2600 Series, H8S/2000 Series Software Manual for a detailed
description of the instruction set.
Notes on reading this manual:
• In order to understand the overall functions of the chip
