Resources for RA2A1
Description
The RA2A1 group is a high-performance, low-power analog microcontroller based on an Arm® Cortex®-M23 core with a 48MHz clock frequency and a wide range of analog front ends, including two types of A/D converters. This group supports a 16-bit SAR A/D converter, a 24-bit sigma-delta A/D converter, a 12-bit D/A converter, comparators, and operational amplifiers. These functions are suitable for applications that measure and adjust sensor signals with high accuracy. In addition, UART, I2C, simple SPI, CAN, and USB 2.0 Full-Speed are also integrated as peripheral functions, enabling easy communication with other devices. The RA2A1 supports a wide operating voltage range of 1.6V to 5.5V, enabling communication with devices operating at 5V without level shifters. The RA2A1 MCU targets industrial sensor applications with low power consumption and low-cost advantage.
