The NANO103SD3AE ultra low power microcontroller based on the Arm® Cortex®-M0 core operates at up to 36 MHz with < 1uA standby current and independent RTC VBAT power source. It supports up to 64 Kbytes Flash memory, 16 Kbytes SRAM and 4 Kbytes ISP (In-System Programming) ROM in 64-pin package. The integrated HIRC supports multiple frequencies of 4/12/36 MHz with 1% accuracy to meet diversified requirements, and to save power consumption without applying PLL (Phase-lock Loop).

The exceptionally low power consumption makes it widely used in battery-powered devices, especially the OLED display applications such as the automatic door locks, healthcare products, and meters. 

The NANO103SD3AE operates at 1.8V to 3.6V and from -40°C to 105°C. The integrated HIRC supports multiple frequencies of 4/12/36 MHz with <1% deviation to meet diversified requirements. It supports rich peripherals such as Timer, WDT/WWDT (Watchdog Timer/Window Watchdog Timer), RTC, PDMA, UART, SPI, I²C, PWM, ISO-7816, and a high-speed 1.8 MSPS 12-bit SAR ADC, temperature sensor, LVR (Low Voltage Reset), BOD (Brown-out Detector), 96-bit UID (Unique Identification), and 128-bit UCID (Unique Customer Identification) to provide multiple protection for program development.

Target Application:

Smart Door Lock, Wearable Devices, Portable Healthcare Devices, LPWAN Connectivity Module, Smart Remote Controller, Smart Home, Card Reader, GPS Tracker, Payment Device, etc.
