Operating voltage: (1.5 – 3.6 V) I2C or SPI serial interfaces The “Aptinex Ultra-Low Power RTC” module provides an easy real time clock solution for applications such as utility meters, medical electronics, communication equipment and multitude of other devices. Since the module requires significantly lower power than most real time clocks available in the market (14nA – 55nA) it is extremely suitable for applications that require very low power consumption. The RTC includes various features that can be used as required by the implementation, making it a versatile component and a desirable choice. The module can be ordered either with SPI or I2C communication functionalities. The Aptinex Ultra-Low Power RTC Module includes the AM1815 IC by Ambiq Micro which is an ultra-low power IC which includes a highly sophisticated feature set. This RTC requires significantly less power than any other industrial alternatives due to the innovative power optimization technologies provided by Ambiq Micro. The AM1815 chip on the module provides minimal power consumption, complete RTC functions which includes battery backup, programmable counters, alarms for timers and watchdog functions, and I2C serial communication capabilities. These features of integrated chip including its integrated power switch and its sophisticated sleep functionalities makes the module suitable for be used as a supervisory component for a host microcontroller-based system.
