• Manufacturer Part Number: h8s-2161b
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2100 Series
• Manufacturer: Renesas Electronics Corporation.

The H8S/2140B Group are microcomputers (MCUs) made up of the H8S/2000 CPU employing
Renesas Technology original architecture as their cores, and the peripheral functions required to
configure a system.
The H8S/2000 CPU has an internal 32-bit configuration, sixteen 16-bit general registers, and a
simple and optimized instruction set for high-speed operation. The H8S/2000 CPU can handle a
16-Mbyte linear address space.
This LSI is equipped with a data transfer controller (DTC) as a bus master, ROM, RAM, an 8-bit
PWM timer (PWM), a 14-bit PWM timer (PWMX), a 16-bit free-running timer (FRT), an 8-bit
timer (TMR), timer connection, a watchdog timer (WDT), a serial communication interface (SCI),
a keyboard buffer controller, a host interface X-bus interface (XBS), a host interface LPC interface
(LPC), an 8-bit D/A converter, a 10-bit A/D converter, and I/O ports as on-chip peripheral
modules required for system configuration. An I
optional interface.
A high-functionality bus controller is also provided, enabling fast and easy connection of DRAM
and other kinds of memory.

it can be reprogrammed in no time to cope with all situations from the early stages of mass
production to full-scale mass production. This is particularly applicable to application devices with
specifications that will most probably change.
