Overview
The H8S/2245 Group is a series of microcomputers (MCUs: microcomputer units), built around
the H8S/2000 CPU, employing Renesas Technology proprietary architecture, and equipped with
peripheral functions on-chip.
The H8S/2000 CPU has an internal 32-bit architecture, is provided with sixteen 16-bit general
registers and a concise, optimized instruction set designed for high-speed operation, and can
address a 16-Mbyte linear address space. The instruction set is upward-compatible with H8/300
and H8/300H CPU instructions at the object-code level, facilitating migration from the H8/300,
H8/300L, or H8/300H Series.
On-chip peripheral functions required for system configuration include data transfer controller
(DTC) bus masters, ROM and RAM, a 16-bit timer-pulse unit (TPU), 8-bit timer, watchdog timer
(WDT), serial communication interface (SCI), A/D converter, and I/O ports.
The on-chip ROM is either PROM (ZTAT ) or mask ROM, with a capacity of 128 kbytes,
64 kbytes, or 32 kbytes. ROM is connected to the CPU via a 16-bit data bus, enabling both byte
and word data to be accessed in one state. Instruction fetching has been speeded up, and
processing speed increased.
Seven operating modes, modes 1 to 7, are provided, and there is a choice of address space and
single-chip mode or external expansion mode.
The features of the H8S/2245 Group are shown in table 1.1.
