• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2100 Series
• Manufacturer: Renesas Electronics Corporation.

Preface
The H8S/2138 Group and H8S/2134 Group 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), host interface (HIF), D/A converter (DAC), A/D converter (ADC), and I/O ports. An
2
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/2138 Group has all the above on-chip supporting functions, and can also be provided
with an IIC module as an option. The H8S/2134 Group comprises reduced-function versions, with
fewer TMR channels, and no PWM, HIF, IIC, or DTC modules.
Use of the H8S/2138 or H8S/2134 Group 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 interconnectability (timer
2
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 system 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.
This manual describes the hardware of the H8S/2138 Group and H8S/2134 Group. Refer to the
H8S/2600 Series and H8S/2000 Series Software Manual for a detailed description of the
instruction set.
