MCU RA2A2 ARM CM23 48MHz 512K/48K LFQFP100 The RA2A2 group is based on the Arm® Cortex®-M23 core and provides rich peripheral features targeting a wide range of applications. With the capabilities of high-resolution ADC, continuous firmware update, segment LCD and low power operation, users can simplify their system design and reduce both system cost and footprint.The entry-line, single chip 32-bit Arm MCU advances the RA family’s rich analog portfolio segment with rich peripheral features to deliver better design experience that allows high level analog sensing while reducing power consumption, system cost and overall footprint.24-bit ADC realizes low-power & high-resolution AD conversion for power consumption sensitive applications.Dual bank code flash and bank swap function make it easy to implement FOTA for continuous operation.Multiple power structures and voltage detection hardware to realize energy-efficient, ultra-low power operation.RA2A2 targets energy management and general-purpose applications by supporting 24-bit sigma delta ADC, dual bank code flash, segment LCD, independent power supply RTC and segment LCD.One of RA2A2’s prime target applications is next-generation smart electricity meter and RA2A2 meets all the requirements of this application by supporting below functions:8KHz/4KHz hybrid sampling for NILM (Non-Instructive Load Monitoring)Firmware update without interrupting metrologyPower management by multiple power structure, voltage detection hardware and independent power supply RTCHardware accelerator of AES128/256bit: ECB/CBC/CTR/GCM/CMAC/CCM modeRA2A2 is also suitable for general-purpose applications that require continuous firmware update and segment LCD with low power operation. The package option supports 64-pin to 100-pin with LFQFP package.
