Overview
Description
The RA2E3 group is an entry-line, single-chip microcontroller in the RA family based on the 48MHz Arm® Cortex®-M23 core with up to 64KB code flash and 16KB SRAM memory. RA2E3 MCUs provide an optimized feature set for cost-sensitive applications by supporting pin-to-pin and peripheral compatibility with RA2E1 MCUs. Ultra-low power consumption contributes to energy-efficient system design, required for IoT applications and battery-operated systems to achieve longer battery life.
Features
- 48MHz Arm Cortex-M23 Core
- Up to 64KB flash memory and 16KB SRAM
- 2KB data flash memory (100,000 program/erase (P/E) cycles)
- Package options of 32-pin and 48-pin
- Wide voltage range of 1.6V to 5.5V
- 16-bit general-purpose timers, 32-bit general-purpose timer, and 16-bit low-power asynchronous general-purpose timers
- 12-bit A/D converter and temperature sensor
- SCI (UART, Simple SPI, Simple I2C), SPI, and I2C bus
- Safety functions
