Description
Key features include a dual alarm system, programmable square wave output, and 96 bytes of battery-backed SRAM for non-volatile data storage. The DS1306EN+T&R is powered by a primary supply (VCC), with an automatic switch to a backup battery (VBAT) when the main power source fails, ensuring continuous timekeeping.
The RTC is encapsulated in a compact surface-mount package, ideal for use in various applications like consumer electronics, automotive systems, and industrial equipment. The "+T&R" designation indicates that the product is supplied in tape and reel packaging, suitable for automated assembly processes.
