The H8S/2345 Group is a group of high-performance microcontrollers with the internal 32-bit H8S/2000 CPU core, and a set of on-chip supporting functions required for system configuration.
Operating frequency (MHz)/Supply voltage (V)
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. With regard to on-chip ROM, single power supply flash memory, PROM (OTP), and mask ROM versions are available, providing a quick and flexible response to conditions from ramp-up through fullscale volume production, even for applications with frequently changing specifications.
On-chip supporting functions include a 16-bit timer pulse unit (TPU), 8-bit timers, watchdog timer (WDT), serial communication interface (SCI), A/D converter, D/A converter, and I/O ports.
An on-chip data transfer controller (DTC) is also provided, enabling high-speed data transfer without CPU intervention.
Use of the H8S/2345 Group enables compact, high-performance systems to be implemented easily.
