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 generalregisters, 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-bitfree-running timer (FRT), an 8-bit timer (TMR), timer connection, a watchdogtimer (WDT), a serial communication interface (SCI), a keyboard buffercontroller, a host interface X-bus interface (XBS), a host interface LPCinterface (LPC), an 8-bit D/A converter, a 10-bit A/D converter, and I/O portsas on-chip peripheral modules required for system configuration. AnI2C bus interface (IIC) can also be included as an optionalinterface.
A high-functionality bus controller is also provided, enabling fast and easyconnection of DRAM and other kinds of memory.
A flash memory version is available for this LSI's ROM. This providesflexibility as it can be reprogrammed quickly to cope with all situations fromthe early stages of production to full-scale mass production. This isparticularly applicable to application devices with specifications that willmost probably change.
