Datasheet Summary
Powered by GS/AI

The AB1803-T3 is a real-time clock (RTC) from Quarktwin Technology Ltd. designed for ultra-low power applications, featuring a supply current as low as 14 nA with an RC oscillator. It operates within a voltage range of 1.5 to 3.6 V and supports an operating temperature range of -40 to 85 ¬8C. The device includes a 32.768 kHz crystal oscillator, programmable counters for timekeeping, alarm capabilities, and a countdown timer. The AB1803-T3 also offers advanced features such as automatic calibration of the RC oscillator to the crystal oscillator, a watchdog timer, and up to 64 bytes of general-purpose RAM. Power management capabilities include an integrated power switch, a system sleep manager, and programmable low battery detection. Communication is facilitated through I2C (up to 400 kHz) or SPI (up to 2 MHz) interfaces. The product is packaged in a compact 3x3 mm QFN-16 format, making it suitable for various applications including smart cards, wireless sensors, medical electronics, and consumer devices.
