Overview

Description

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.

Features

  • 48MHz Arm® Cortex®-M23
  • 256kB Flash memory and 32kB SRAM
  • 8kB Data Flash to store data as in EEPROM
  • Scalable from 32-pin to 64-pin packages
  • Capacitive touch sensing unit
  • 16-bit SAR A/D, 24-bit SD A/D
  • 12-bit D/A, 8-bit D/A
  • OPAMP (3ch), ACMP-HS/LP
  • USB 2.0 Full Speed
  • CAN 2.0
  • SCI (UART, Simple SPI, Simple I2C)

Applications

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
