SH7144 Datasheet, PDF (7/773 Pages) Renesas Technology Corp – Hitachi SuperH RISC engine

Preface
The SH7144 Series single-chip RISC (Reduced Instruction Set Computer) microprocessor
includes a Hitachi-original RISC CPU as its core, and the peripheral functions required to
configure a system.
Target users: This manual was written for users who will be using this LSI in the design of
application systems. Users of this manual 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 this LSI to the above users.
Refer to the SH-1, SH-2, SH-DSP Programming Manual for a detailed description
of the instruction set.

In this manual, the product abbreviations are used to distinguish products. For example, 112-
pin products are collectively referred to as the SH7144, an abbreviation of the basic type's
classification code, while 144-pin products are collectively referred to as the SH7145. There
are two versions of each: a flash memory version and a mask ROM version. When a
description is limited to the flash memory version alone, the character F is added at the end of
the abbreviation, such as SH7144F. When a description is limited to the mask ROM version
alone, an abbreviation that is determined by adding M at the end of the abbreviation.
