ARM MCU, RA Family, RA2 Series, RA2L1 Group Microcontrollers, ARM Cortex-M23, 32bit, 48 MHzProduct OverviewRA family, RA2L1 group, ultra low power 48MHz Arm® Cortex®-M23 microcontrollerin LFQFP-48 package. RA2L1 MCU group is part of the RA2 MCU series, it iscurrently the smallest member of the RA family. It is a combination ofmicrocontroller with standard communication and timing peripherals,general-purpose analogue and new innovative capacitive touch sensing unit withbest-in-class performance. When benchmarked for power consumption, RA2L1received a ULPMark score of 226, as certified by EEMBC®, the embeddedmicroprocessor benchmark consortium. It provides superior low power consumptionin active and sleep/standby modes. RA2L1 integrates unique peripheral blockssuch as CTSU2. Designers can easily add touch interfaces that provide animpressively smooth and efficient user experience in presence of moisture andnoise while maintaining low power consumption. Touch interface makes RA2L1devices ideal for appliance, medical and consumer human-machine interfaceapplications.256KB code flash memory, 32KB SRAM, 8KB data flashCapacitive sensing unit 2 (CTSU), 12bit A/D converter, multiple clock sources,12bit D/A converterSCI × 5, SPI × 2, I2C bus (IIC) × 2, CAN module (CAN), power-on resetLow power analogue comparator (ACMPLP) × 2, temperature sensor (TSN)General PWM timer 32bit (GPT32) × 4, general PWM timer 16bit (GPT16) × 6AES128/256, true random number generator (TRNG)Low power modes, switching regulator, real time clock (RTC), event linkcontroller (ELC)Independent watchdog timer (IWDT), cyclic redundancy check (CRC) calculatorOperating temperature range from -40°C to +85°C, 1.6 to 5.5V operating voltageProduct InformationProduct Range: RA Family, RA2 Series, RA2L1 Group MicrocontrollersDevice Core: ARM Cortex-M23No. of Bits: 32bitData Bus Width: 32bitOperating Frequency Max: 48MHzCPU Speed: 48MHzProgram Memory Size: 256KBRAM Memory Size: 32KBIC Case / Package: LFQFPNo. of Pins: 48PinsMCU Case Style: LFQFPInterfaces: CAN, I2C, SPI, UARTEmbedded Interface Type: CAN, I2C, SPI, UARTSupply Voltage Min: 1.6VSupply Voltage Max: 5.5VMCU Family: RAMCU Series: RA2MSL: MSL 3 - 168 hours
