The RA2A1 group uses the high-performance Arm® Cortex®-M23 core and offers highly integrated, high-accuracy analog capabilities and therefore offers 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 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.48MHz Arm® Cortex®-M23 256kB Flash Memory and 32kB SRAM 8kB DataFlash to store data as in EEPROM Scalable from 32pin to 64pin Packages Capacitive Touch Sensing Unit 16bit-SAR A/D, 24bit-SD A/D 12bit-D/A, 8bit-D/A OPAMP (3ch), ACMP-HS/LP USB2.0 Full Speed CAN 2.0 SCI (UART, Simple SPI, Simple I2C) Applications Industrial Automation (Photoelectric Sensor, Fiber Sensor,Temperature Sensor) Process Automation (Pressure Sensor, Flow control meter,Single Phase Meter) Building Automation/Home Appliance (Smoke Detector) Healthcare (Pulse Oximeters, Body Composition Measurement) General Purpose More information:  | | Family Name: | RA2A1 | Package Type: | LQFP | Mounting Type: | Surface Mount | Pin Count: | 32 | Device Core: | ARM Cortex M23 | Data Bus Width: | 32bit | Program Memory Size: | 256 kB | Maximum Frequency: | 48MHz | RAM Size: | 32 kB | USB Channels: | 1 | Number of SPI Channels: | 2 | Number of CAN Channels: | 1 | Number of I2C Channels: | 2 | Number of UART Channels: | 1 | Number of USART Channels: | 0 |
