Renesas RL78/G23 Unique ID Read Driver

Introduction to the Application Note

This document serves as an application note from Renesas, detailing the functionality and usage of the Unique ID Read Driver for the RL78/G23 microcontroller series.

The RL78/G23 microcontroller features a unique ID programmed into each chip, which is crucial for preventing unauthorized software IP usage and for individual product management. This application note explores practical usage examples of this unique ID.

It provides comprehensive guidance on how to implement the unique ID read driver, which reads a 16-byte unique ID and a 9-byte product name (stored as ASCII code) from the device's extra area. The document outlines the software configuration, available API functions, and includes a sample project to demonstrate the driver's application in real-world scenarios.

Key benefits include enhanced product security and streamlined product lifecycle management.
