Overview
Description
The Renesas Solution Starter Kit for RX23E-B is an evaluation tool designed for sensor measurement using the RX23E-B 32-bit microcontroller (MCU). The kit includes an RX23E-B MCU evaluation board equipped with peripherals for sensor measurements and software that can be downloaded from our website. Analog characterization can be started immediately after purchasing the kit. This kit allows developers to shorten development time and bring their products to market faster.
This RSSK consists of an evaluation module equipped with the RX23E-B MCU, our Quick and Effective tool solution for AFE (QE for AFE), and a board control program that communicates with QE for AFE and controls the analog front end, A/D converter, and D/A converter.
The evaluation board is equipped with circuits for A/D conversion, thermocouple measurement, resistance temperature detector measurement, load cell measurement, and D/A converter output, supporting the evaluation of A/D and D/A converters and application evaluation using various sensors.
QE for AFE, a GUI-based support tool, can be combined with a factory board control program to set the operation of the AFE, A/D converter, and D/A converter, and to acquire and display A/D conversion results.
The kit also includes various application notes and sample programs providing developers with further guidance and support.

AI-generated Summary:
Azure RTOS sample projects demonstrate how to develop applications using ThreadX, FileX, GUIX, NetX Duo, and USBX on Renesas RX family microcontrollers with e2 studio or IAR Embedded Workbench. The projects support various RX devices and include examples for IoT connectivity, low power operation, and secure bootloader integration. Microsoft has contributed Azure RTOS to open source under Eclipse ThreadX, discontinuing official updates. Renesas discontinues the RYZ014A LTE module, recommending Sequans GM01Q as a compatible replacement. Development tools and supported sample projects vary by device, with detailed setup instructions and sample descriptions provided.

AI-generated Summary:
The RX23E-B microcontroller outputs temperature or voltage measurements as a 4-20mA current signal using its built-in 16-bit D/A converter and high-precision 24-bit Δ-Σ A/D converter. The system supports thermocouple and RTD sensors, enabling accurate long-distance current-based communication with minimal wiring. The sample program runs on the RX23E-B Solution Starter Kit, allowing real-time measurement and current output calibration. Measurements confirm output current errors below 0.1% full scale across temperatures from -25°C to 85°C, with a 95% settling time of 1.3ms dominated by the output filter circuit. The document details hardware configuration, measurement procedures, calibration methods, and software implementation for 4-20mA transmitter applications.
