Hitachi H8S/2378, H8S/2378R Series Hardware Manual page 5

This LSI is a single-chip microcomputer made up of the high-speed H8S/2000 CPU as its core,
and the peripheral functions required to configure a system.
This LSI is equipped with direct memory access controller (DMAC), EXDMA controller
(EXDMAC), and data transfer controller (DTC) bus masters, ROM and RAM memory, a 16-bit
timer pulse unit (TPU), a programmable pulse generator (PPG), 8-bit timers (TMR), a watchdog
timer (WDT), serial communication interfaces (SCI and IrDA), an I
bit A/D converter, an 8-bit D/A converter, and I/O ports as on-chip peripheral modules required
for system configuration.
This LSI is suitable for use as an embedded processor for high-level control systems. Its on-chip
ROM is flash memory (F-ZTAT
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/2378 Series 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/2378 Series 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 20,
List of Registers.
