Renesas Electronics RA2A1 32-Bit Microcontroller Group

Renesas Electronics RA2A1 32-Bit Microcontroller Group is based on the high-performance Arm® Cortex®-M23 core. The RA2A1 MCUs offer highly integrated, high-accuracy analog capabilities, which are ideal for signal conditioning and measurement. The RA2A1 MCUs include a 16-bit Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC), 24-bit Sigma Delta (ΣΔ) ADC, comparators, operational amplifiers, and Digital-to-Analog Converters (DAC). The RA2A1 MCUs target cost-sensitive and low-power industrial sensor applications where high-resolution analog will become a cost benefit.
