    RA_DFP

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 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.

Applications

- Industrial automation (photoelectric sensor, fiber sensor, temperature sensor)
- Building automation/home appliance (smoke detector)
- Healthcare (pulse oximeters, body composition measurement)
- General purpose
