Preface
This LSI is a single-chip microcomputer made up of the H8S/2000 CPU with an internal 32-bit
architecture as its core, and the peripheral functions required to configure a system.
This LSI is equipped with ROM, RAM, a bus controller, data transfer controller (DTC), a 16-bit
timer pulse unit (TPU), a watchdog timer (WDT), a serial communication interface (SCI), a D/A
converter, an A/D converter, and I/O ports as on-chip supporting modules. This LSI is suitable for
use as an embedded processor for high-level control systems. Its on-chip ROM are flash memory
(F-ZTAT™*) and mask ROM that provides flexibility as 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.
