Overview

Description

The RX23E-A group microcontrollers are equipped with an analog front-end that can measure temperature, pressure, flow, and weight with less than 0.1% precision without calibration, making it ideal for high-precision sensing, test and measurement equipment. The CPU is equipped with an RXv2 core that excels in DSP/FPU operations, enabling high-accuracy measurement, control and communication with a single chip.

Features
