H8S-2111 Datasheet, PDF (6/582 Pages) Renesas Technology Corp – 16-Bit Single-Chip Microcomputer

Preface
The H8S/2111B is a microcomputer (MCU) made up of the H8S/2000 CPU employing Renesas
Technology's original architecture as its core, and the peripheral functions required to configure a
system.
The H8S/2000 CPU has an internal 32-bit configuration, sixteen 16-bit general registers, and a
simple and optimized instruction set for high-speed operation. The H8S/2000 CPU can handle a
16-Mbyte linear address space.
This LSI is equipped with ROM, RAM, a 16-bit free-running timer (FRT), an 8-bit timer (TMR),
a watchdog timer (WDT), a serial communication interface (SCI), a keyboard buffer controller, a
host interface (LPC), an I²C bus interface (IIC), and I/O ports as on-chip peripheral modules,
required for system configuration.
A flash memory (F-ZTAT^TM*) version is available for this LSI's ROM. This 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.

Target Users: This manual was written for users who will be using the H8S/2111B in the design
of application systems. Target users 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/2111B to the target users.
Refer to the H8S/2600 Series, H8S/2000 Series Programming Manual for a
detailed description of the instruction set.
Notes on reading this manual:
• In order to understand the overall functions of the chip
Read the manual according to the contents. This manual can be roughly categorized into parts
on the CPU, system control functions, peripheral functions and electrical characteristics.
• In order to understand the details of the CPU's functions
Read the H8S/2600 Series, H8S/2000 Series Programming Manual.
• In order to understand the details of a register when its name is known
Read the index that is the final part of the manual to find the page number of the entry on the
register. The addresses, bits, and initial values of the registers are summarized in section 21,
List of Registers.
