NANO103LD3AE

The NANO103LD3AE ultra low power microcontroller based on the Arm^® Cortex^® -M0 core operates at up to 36 MHz with < 1uA standby current and independent RTC V_BAT power source. It supports up to 64 Kbytes Flash memory, 16 Kbytes SRAM and 4 Kbytes ISP (In-System Programming) ROM in 48-pin packages. 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. To enhance data security, the NANO103LD3AE also provides a secure data protection area called KPROM (Key Protection ROM) to protect the programming code and data in the Flash memory from being maliciously erased or programmed.

The NANO103LD3AE 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.
