RX23E-A MCUs

Renesas Electronics RX23E-A MCUs are 32MHz and 32-bit RX MCUs with built-in FPU and up to 256KB flash. These MCUs are equipped with an Analog Front End (AFE) that helps in measuring pressure, flow, temperature, and weight with less than 0.1% precision. These MCUs also feature two low-noise and low-drift 24-bit delta-sigma A/D converters, rail-to-rail programmable gain instrumentation amplifiers, low-drift voltage reference, and on-chip excitation current sources. The RX23E-A MCUs are capable of simultaneous measurements using the low-noise and low-drift 24-bit delta-sigma A/D converters with extremely stable on-chip voltage reference. These MCUs offer solution kits (RSSK) for quick and easy setup of analog configuration and calibration on packaged PC GUI software. The RX23E-A MCUs are ideal for building automation, broad-based IoT applications, and IA sensing applications like temperature controllers, pressure sensors, data recorders, weight scales, and force sensors.
