Product Overview:

The H8S/2140B Group are microcomputers (MCUs) made up of the H8S/2000 CPU, and the peripheral functions required to configure a system.
The H8S/2000 CPU has an internal 32-bit configuration, sixteen 16-bit general registers, and a simple and optimized instruction set for high-speed operation. The H8S/2000 CPU can handle a 16-Mbyte linear address space.
This LSI is equipped with a data transfer controller (DTC) as a bus master, ROM,RAM, an 8-bit PWM timer (PWM), a 14-bit PWM timer (PWMX), a 16-bit free-running timer (FRT), an 8-bit timer (TMR), timer connection, a watchdog timer (WDT), a serial communication interface (SCI), a keyboard buffer controller, a host interface X-bus interface (XBS), a host interface LPC interface (LPC), an 8-bit D/A converter, a 10-bit A/D converter, and I/O ports as on-chip peripheral modules required for system configuration. An I2C bus interface (IIC) can also be included as an optional interface.
A high-functionality bus controller is also provided, enabling fast and easy connection of DRAM and other kinds of memory.
A flash memory version is available for this LSI's ROM. This provides flexibility as it can be reprogrammed in no time 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.
