Solution Starter Kit for RX23E-A

Accurately and easily evaluate analog performance of high-precision analog front-end integrated in RX23E-A Group of RX Family

The kit consists of an evaluation board with the RX23E-A and peripheral circuits for sensor measurement, a K-type thermocouple, and is provided with the GUI and sample programs. These ready-to-use tools enable users to start evaluation of the A/D converter without hardware modification or software development.

The kit can be utilized to evaluate the measurements of thermocouples, RTD, and strain gauges, which are typical sensors in industrial equipment. Our evaluation of K-type thermocouples using the RSSK shows that the measured temperature error is within 0.6C under environments between -40C and 85C and the effective resolution is 19.4 bit, which means temperature deviation is equivalent to 0.0015C at rms value. The measured temperature error, which is within the sensor error, validates the evaluation board as a reference design.
Refer to application notes for more details of each sensor measurement evaluation.

RX23E-A is a group from the RX MCU family with integrated high-precision analog front-end. Thanks to low noise and low drift of analog front-end features, the high-precision sensor measurement can be achieved with computation performance, system control, and communication in one chip. Refer to the RX23E-A product page for more detail.

The RX23E-A Renesas Solution Starter Kit (RSSK) includes an RX23E-A mounted evaluation board with sensor measurement peripheral circuits. By using it with software downloadable from the website, users can start evaluating analog features right after unboxing. The kit helps users shorten development period and improve time-to-market.
