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), I²C 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.
