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
2
communication interface (SCI), PS/2-compatible keyboard buffer controller, I
C 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.
