The AM0805AQ is a highly integrated, low power real-time clock device that offers a timekeeping accuracy of ±1 minutes per month. It has an on-chip oscillator and provides 8-bit or 16-bit long words with various 16-bit registers. This real-time clock allows users to make corrections to the timekeeping schedule as well as to maintain the time/date information in a non-volatile memory. In addition, the device can be powered down in order to save energy, but will still be able to issue an alarm or interrupt when needed.
The AM0805AQ is an ideal solution for applications such as wristwatches, navigation systems and embedded applications. The device is also suitable for use in other applications where accurate timekeeping is vital.
The AM0805AQ works by incorporating several advanced features, such as an extending time base for accurate timekeeping, a temperature compensation logic for optimum response time and a circuit to detect time discrepancies with a resolution of 1 second. These features allow the device to have a more accurate timekeeping accuracy than many other real-time clocks.
The AM0805AQ also supports three interrupt sources: a timer interrupt, an alarm interrupt, and a time discrepancy interrupt. The timer interrupt can be configured to trigger at a predefined time, allowing for the scheduling of specific tasks to be carried out at regular intervals. The alarm and time discrepancy interrupts are triggered whenever an alarm or a time discrepancy of more than 1 second is detected. This enables the device to provide advanced real-time clock function to its users.
The device can be used in applications such as smart watches, Bluetooth interoperability, radio receivers, gaming consoles and embedded applications. Its low power operation also makes it ideal for battery powered applications. The AM0805AQ is designed in a 48-pin LQFP package and is available in either 5V or 3.3 V operating voltage.
In conclusion, the AM0805AQ is an advanced and highly integrated real-time clock device that offers a timekeeping accuracy of ±1 minutes per month and is suitable for applications where accurate timekeeping is required. Its low power operation, interrupt capability, and temperature compensation make it an ideal solution for a range of applications.
