5 / 845 page  Rev. 3.00 Mar 21, 2006 page v of liv Preface The H8S/2140B Group are microcomputers (MCUs) made up of the H8S/2000 CPU employing Renesas Technology original architecture as their cores, 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 I 2C 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 (F-ZTAT TM *) 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. Note: * F-ZTAT is a trademark of Renesas Technology Corp. Target Users: This manual was written for users who will be using the H8S/2140B Group in the design of application systems. Target users are expected to understand the fundamentals of electrical circuits, logical circuits, and microcomputers. Objective: This manual was written to explain the hardware functions and electrical characteristics of the H8S/2140B Group to the target users. Refer to the H8S/2600 Series, H8S/2000 Series Programming Manual for a detailed description of the instruction set. Notes on reading this manual: • In order to understand the overall functions of the chip Read the manual according to the contents. This manual can be roughly categorized into parts on the CPU, system control functions, peripheral functions and electrical characteristics. |
