Preface
The H8S/2148 Group, H8S/2144 Group, and H8S/2147N comprise 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™ * ) and mask ROM versions are 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), PS/2-compatible keyboard buffer controller, host interface (HIF), D/A converter
2
(DAC), A/D converter (ADC), and I/O ports. An I
C bus interface (IIC) can also be incorporated
as an option.
An on-chip data transfer controller (DTC) is also provided, enabling high-speed data transfer
without CPU intervention.
The H8S/2148 Group has all the above on-chip supporting functions, and can also be provided
with an IIC module as an option. The H8S/2144 Group comprises reduced-function versions, with
fewer TMR channels, and no PWM, keyboard buffer controller, HIF, IIC, or DTC modules, and
the H8S/2147N with fewer TMR channels, no DTC and some other functions.
Use of the H8S/2148 Group, H8S/2144 Group, H8S/2147N 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, while the various timer functions and their
2
interconnectability (timer connection), plus the interlinked operation of the I
C bus interface and
data transfer controller (DTC), in particular, make these devices ideal for use in PC monitors. In
addition, the combination of F-ZTAT™ * and reduced-function versions is ideal for applications
such as CD-ROM drive units in which on-chip program memory is essential to meet performance
requirements, product start-up times are short, and program modifications may be necessary after
end-product assembly.
