This LSI is a microcomputer (MCU) made up of the H8S/2000 CPU with Renesas Technology original architecture as its core, and the peripheral functions required to configure a system, eg PC server. 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. The instruction set of the H8S/2000 CPU maintains upward compatibility at the object level with the H8/300 and H8/300H CPUs. This allows the transition from the H8/300, H8/300L, or H8/300H to the H8S/2000 CPU. This LSI is equipped with ROM, RAM, two kinds of PWM timers (PWM and PWMX), a 16-bit free running timer (FRT), an 8-bit timer(TMR), a watchdog timer (WDT), a serial communication interface (SCI), an I2 C bus interface (IIC), an LPC interface (LPC), a D/A converter, an A/D converter, and I/O ports as on-chip peripheral modules required for systemconfiguration. A data transfer controller (DTC) is included as a bus master. A flash memory version is available for this LSI in 256, 384, and 512-kbyte ROM. The CPU and ROM are connected to a 16-bit bus, enabling byte data and word data to be accessed in a single state. This improves the instruction fetch and process speeds. Two operating modes are provided, offering a choice of address space and single chip mode/external extended mode. Boot programming into a flash memory, on-chip emulation, and boundary scan can be selected as special operating modes.
