Latest Updates

Overview

The H8S family has an wide-ranging lineup of product series to meet the demands of various customer applications.
Diverse customer needs can be met with on-board interfaces for applications such as LPC, BMC, ISA bus controller, I2C, USB, CAN, IE bus controller and LCD controller. 3 V/5 V - I/F combination and high-speed low-voltage operations are also supported.
H8S products consist of static circuits.(This is what the S in H8S refers to.)Additionally, the H8S family allows provision as IP of various peripheral functions, including CPU cores, and also smooth development of ASIC and SOC products.

Key Applications

Notebook PCs, PCservers (BMC), net workservers, printer, multifunction printers, scanner, automobile LANs, car audio systems, automobile meters, mobile phones, ePOS systems, card reader, TVs, flat-panel displays(LCD, PDP, projector)

Renesas MCU Selection Guide

H8S Family Selection by Application and Application Field

HCAN: The HCAN is a module for controlling a controller area network (CAN) for realtime communication in vehicular and industrial equipment systems, etc. For details on CAN specification, refer to Bosch CAN Specification Version 2.0 1991, Robert Bosch GmbH.

IEbus: Supports all modes in which transfer speeds differ, from "Mode 0" to "Mode 2". Using data transmission by DTC, CPU load is reduced sharply (Approx. 1/2). Using abundant error status flags to realize appropriate error processing Note: IEBus is a trademark of NEC Electronics Corporation.

USB: Suitable for a wide range of systems, including audio equipment, electronic game machines, printers, scanners, modems, and otehr PC peripherals.
