Preface
This LSI is a high-performance microcontroller (MCU) made up of the H8S/2000 CPU with an
internal 32-bit configuration as its core, and the peripheral functions required to configure a
systemw. ww.DataSheet4U.com
A single-power flash memory (F-ZTATTM)* version and a masked-ROM version are available for
this LSI's ROM. The F-ZTAT version 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/2268 Group and
H8S/2264 Group 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/2268 Group and H8S/2264 Group 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 24,
List of Registers.
Examples: Register name: The following notation is used for cases when the same or a
similar function, e.g. 16-bit timer pulse unit or serial
communication, is implemented on more than one channel:
XXX_N (XXX is the register name and N is the channel
number)
Bit order:
The MSB is on the left and the LSB is on the right.
