Overview
The H8S/2345 Group is a series of microcomputers (MCUs: microcomputer units), built around
the H8S/2000 CPU, employing Renesas’ 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), an 8-bit timer, a watchdog
timer (WDT), a serial communication interface (SCI), an A/D converter, a D/A converter, and I/O
ports.
The on-chip ROM *
is either single power supply flash memory (F-ZTAT™ *
1
2
), PROM
(ZTAT ®*
2
), or mask ROM, with a capacity of 128, 96, 64, 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/2345 Group are shown in table 1.1.
Notes: 1. The H8S/2345, H8S/2344, H8S/2343, and H8S/2341 have on-chip ROM. The
H8S/2340 does not have on-chip ROM.
