Overview

The RA2A1 group of microcontrollers (MCUs) uses a high-performance Arm® Cortex®-M23 core and offers highly integrated, high-accuracy analog capabilities. This group of ICs offers a complete MCU with an analog solution for signal conditioning and measurement. The RA2A1 group supports a wide operating voltage range of 1.6V to 5.5V. It includes a 16-bit SAR ADC, 24-bit Sigma-Delta ADC, comparators, operational amplifiers, and DACs. The RA2A1 MCU targets cost-sensitive and low-power industrial sensor applications where high-resolution analog will become a cost-benefit.
