An Indispensable Element in Single Board Computer Design:Real Time Clock perceptive-ic.com

The main characteristics of a single-board computer (SBC) are not only closely related to the performance of the processor and the size and speed of the memory, but also highly dependent on its connectivity and expansion options.

These options may include GPIO pins, WiFi, Bluetooth, antennas, audio interfaces (headphones and microphones), HDMI ports, storage solutions such as Micro SD, M.2 (M-Key), or eMMC, various connectors, and software compatibility. Some SBCs even come with heat sinks and fans.
What about real-time time tracking?

Real Time Clocks (RTCs) play a key role in embedded systems by enabling them to accurately track time and date when the device is disconnected from the network or the main power supply is turned off. The RTC is powered by a specialized battery, which allows it to continue running even when system power is turned off.

RTC has applications in a variety of situations, including industrial manufacturing, commercial machine maintenance, medical equipment management, agricultural facilities, and more. Therefore, an SBC board with RTC function should be integrated in any electronic equipment that requires real-time monitoring.

To optimize performance and form factor, the best option is a fully embedded RTC module. In this module, a 32.768 kHz crystal along with CMOS based oscillator and RTC integrated circuit IC are packaged in a small SMD ceramic package.
