Preface

The H8S/2149 and H8S/2169 F-ZTAT™ comprises high-performance microcomputers with a 32-

bit H8S/2000 CPU core, and a set of on-chip supporting functions required for system

configuration.

The H8S/2000 CPU can execute basic instructions in one state, and is provided with sixteen

internal 16-bit general registers with a 32-bit configuration, and a concise and optimized

instruction set. The CPU can handle a 16-Mbyte linear address space (architecturally 4 Gbytes).

Programs based on the high-level language C can also be run efficiently.

Single-power-supply flash memory (F-ZTAT™*) is available, providing a quick and flexible

response to conditions from ramp-up through full-scale volume production, even for applications

with frequently changing specifications.

On-chip peripheral functions include a 16-bit free-running timer (FRT), 8-bit timer (TMR),

watchdog timer (WDT), two PWM timers (PWM and PWMX), a serial communication interface

(SCI, IrDA), I

2C bus interface (IIC), PS/2-compatible keyboard buffer controller, host interface

(HIF:XBS and LPC), D/A converter (DAC), A/D converter (ADC), and I/O ports.

An on-chip data transfer controller (DTC) is also provided, enabling high-speed data transfer

without CPU intervention.

Use of the H8S/2149 and H8S/2169 F-ZTAT™ enables compact, high-performance systems to be

implemented easily. The comprehensive PC-related interface functions and 16

× 8 matrix key-

scan functions are ideal for applications such as notebook PC keyboard control and intelligent

battery and power supply control. In particular, the provision of two on-chip host interfaces—a

conventional X-BUS (ISA) interface and an LPC interface (a new standard)—provide flexible

support for PC systems in a period of transition.

This manual describes the hardware of the H8S/2149 and H8S/2169 F-ZTAT™. Refer to the

H8S/2600 Series and H8S/2000 Series Programming Manual for a detailed description of the

instruction set.

This manual describes the hardware of the H8S/2149 and H8S/2169 F-ZTAT™. Although the

H8S/2169 is not explicitly mentioned in Section 2 to 7 or Section 9 to 22, the descriptions in these

Sections apply to both the H8S/2149 and H8S/2169.
