Preface
The H8S/2245 Group is a series of high-performance microcontrollers with a 32-bit H8S/2000
CPU core, and a set of on-chip peripheral functions required for system configuration.
The H8S/2000 CPU can execute basic instructions in one state, and is provided with sixteen 16-bit
general registers with a 32-bit internal configuration, and a concise and optimized instruction set.
The CPU can handle a 16 Mbyte linear address space (architecturally 4 Gbytes). Programs based
on the high-level language C can also be run efficiently.
The address space is divided into eight areas. The data bus width and access states can be selected
for each of these areas, and various kinds of memory can be connected fast and easily.
On-chip memory consists of large-capacity ROM and RAM. PROM (ZTAT ) and mask ROM
versions are available, providing a quick and flexible response to conditions from ramp-up through
full-scale volume production, even for applications with frequently changing specifications.
On-chip peripheral functions include a 16-bit timer pulse unit (TPU), 8-bit timers, watchdog timer
(WDT), serial communication interface (SCI), A/D converter, and I/O ports.
In addition, an on-chip data transfer controller (DTC) is provided, enabling high-speed data
transfer without CPU intervention.
Use of the H8S/2245 Group enables compact, high-performance systems to be implemented
easily.
This manual describes the hardware of the H8S/2245 Group. Refer to the H8S/2600 Series and
H8S/2000 Series Software Manual for a detailed description of the instruction set.
