Real time clock battery
The DS1302 trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM. It communicates with a microprocessor via a simple Amazon.com: DS3231 Real Time Clock Module 3.3V/5V with Battery for Raspberry Pi and Arduino by Atomic Market: Home Audio & Theater. 15 May 2014 Ultra-low power Ambiq Micro AM0813 SPI bus RTC with integrated 5uAh ( Lifecycle Capacity =2.5mAh) rechargeable solid state battery with Earlier versions of mobile phones had an off chip(separate) RTC with a backup battery. But most smartphones have an on-chip RTC (inbuilt) to save space. Equipment. Scout VCU; BR2032 Button Cell Battery. In some applications, CR2032 and BR2032 batteries can be used interchangeable, but Miovision RTC Batteries are commonly used in electronic devices to keep accurate time and memory support. A real-time clock is usually found in computers and
Databrief for the EnerChip™ CBC921 PMRTC, combining a real-time clock (RTC ) with a backup battery charger and other power management features.
A real-time clock (RTC) is a battery-powered clock that is included in a microchip in a computer motherboard. This microchip is usually separate from the microprocessor and other chips and is often referred to simply as "the CMOS" (complementary metal-oxide semiconductor). The devices provide a real-time clock/calendar, one time-of-day alarm, three maskable interrupts with a common interrupt output, a programmable square wave, and 114 bytes of battery-backed static RAM (113 bytes in the DS12C887 and DS12C887A). The DS12887 integrates a quartz crystal and lithium energy source into a 24-pin encapsulated DIP package. Dallas Semiconductor (DS1387) real-time clock from an older PC. This version also contains a battery-backed SRAM. A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. The M41T00CAP is a low-power serial real-time clock (RTC) with integral battery and crystal in ST’s 24-pin CAPHAT™ package. It includes a crystal controlled, 32.768 kHz oscillator and has a built-in power sense circuit which detects power failures and automatically switches to the backup battery when a power failure occurs.

A real time clock is basically just like a watch - it runs on a battery and keeps time for you even when there is a power outage! Using an RTC, you can keep track of long timelines, even if you reprogram your microcontroller or disconnect it from USB or a power plug.
The RTC is powered by the CMOS (Complementary Metal Oxide Semiconductor) battery. In older computers, this battery can lose power and may cause RTC
