29 / 1075 page Section 1 Overview Rev. 3.00 Jan 18, 2006 page 1 of 1044 REJ09B0280-0300 Section 1 Overview 1.1 Overview The H8S/2149 and H8S/2169 F-ZTAT™ is a microcomputer (MCU) built around the H8S/2000 CPU, employing Renesas’ original architecture, and equipped with on-chip supporting functions required for system configuration. The H8S/2000 CPU has an internal 32-bit architecture, is provided with sixteen 16-bit general registers and a concise, optimized instruction set designed for high-speed operation, and can address a 16-Mbyte linear address space. The instruction set is upward-compatible with H8/300 and H8/300H CPU instructions at the object-code level, facilitating migration from the H8/300, H8/300L, or H8/300H Series. On-chip supporting functions required for system configuration include a data transfer controller (DTC) bus master, ROM and RAM, a 16-bit free-running timer module (FRT), an 8-bit timer module (TMR), watchdog timer module (WDT), two PWM timers (PWM and PWMX), serial communication interface (SCI), PS/2-compatible keyboard buffer controller, I 2C bus interface (IIC), host interfaces (HIF:LPC and HIF:XBS), D/A converter (DAC), A/D converter (ADC), and I/O ports. The H8S/2169 F-ZTAT™ has all of the same I/O ports as the H8S/2149 F-ZTAT™, plus 40 additional I/O ports. The on-chip ROM is 64-kbyte flash memory (F-ZTAT™*). The ROM is connected to the CPU by a 16-bit data bus, enabling both byte and word data to be accessed in one state. Instruction fetching has been speeded up, and processing speed increased. Three operating modes, modes 1 to 3, are provided, and there is a choice of address space and single-chip mode or externally expanded modes. The features of the H8S/2149 and H8S/2169 F-ZTAT™ are shown in table 1.1. Note: * F-ZTAT is a trademark of Renesas Technology Corp. |
