This LSI is a microcomputer (MCU) made up of the H8S/2600 CPU with Renesas Technology-
original architecture as its core, and the peripheral functions required to configure a system.
The H8S/2600 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/2600 CPU can handle a
16-Mbyte linear address space. The instruction set of the H8S/2600 CPU maintains upward
compatibility at the object level with the H8/300 and H8/300H CPUs. This allows the transition
from the H8/300, H8/300L, or H8/300H to the H8S/2600 CPU.
This LSI is equipped with the flash memory, RAM, two kinds of PWM timers (PWM and
PWMX), a 16-bit free-running timer (FRT), an 8-bit timer (TMR), a 16-bit timer pulse unit (TPU),
a watchdog timer (WDT), a timer connection, a serial communication interface (SCI), an I
interface 3 (IIC3), an A/D converter, and I/O ports as on-chip peripheral modules required for
system configuration.
A flash memory (F-ZTAT
the flash memory are connected to a 16-bit bus, enabling byte data and word data to be accessed in
a single state. This improves the instruction fetch and process speeds.
