Renesas Starter Kit for H8SX/1668

Target Devices

H8SX/1668R (H8SX/1668RF), H8SX/1668M Group

Device Part No. populated on the board: R5F61688RN50FPV (H8SX/1668RF)

Product Overview

The Renesas Starter Kit for H8SX/1668 is intended as a user-friendly introductory and evaluation tool for the H8SX/1668 microcontroller. The board also provides a useful platform for evaluating the Renesas suite of development tools for coding and debugging, using High-performance Embedded Workshop as well as programming the device using E10A emulator.

The Renesas Starter Kit for H8SX/1668 may be connected to the host PC using a simple RS232 serial connection or via the included USB E10A on chip debugging interface.

The purpose of the board is to enable the user to evaluate the capabilities of the device and its peripherals by giving the user a simple platform on which code can be run only minutes from opening box. It can also prove an invaluable tool in development by providing a useful test platform for code already debugged using one of our more powerful emulation tools.
