This document introduces the features and characteristics of SH79F085/SH79F165 products, including package, software installation, target board setup, etc.
The SH79F085 and SH79F165 are 8051‑compatible micro‑controllers with high‑efficiency CPU cores and flash program memory. The note provides the hardware package information and guidelines for in‑circuit programming and debugging using the JET51 driver.
It describes how to install the Keil uVision IDE, add the JET51 driver, connect the target board via JTAG, create and build a project, and download the compiled HEX file to the device’s flash memory. An appendix shows the target‑board layout and power‑supply options.
