Dallas DS1307 RTC chip in DIP-8 package. Many integrated circuit manufacturers make RTCs, including Epson, Intersil, IDT, Maxim, NXP Semiconductors, Texas Instruments, STMicroelectronics and Ricoh. A common RTC used in single-board computers is the Maxim Integrated DS1307.

Our I 2 C and Serial Peripheral Interface (SPI) real-time clocks range from simple, low-cost devices to highly integrated mid-range devices containing additional user available memory (SEEPROM and SRAM) included and a combination of features that are useful when operating within a single battery-backed clock device.

Mar 19, 2015 · The DS3231 is a low-cost, extremely accurate I²C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when …

ST offers a wide portfolio of real-time clock (RTC) ICs with parallel or serial interface, including ultra-low-power devices packaged in standard SMD SOX18 and SOX28 with embedded ±5ppm 32kHz factory-calibrated Crystal.

Feb 26, 2021 · What Are Real-Time Clock (RTC) Chips? An RTC is an electronic device, generally an integrated circuit (IC), which keeps track of the current time and maintains accurate time in electronic systems. It is basically like a timepiece that runs on a battery and maintains current time, even when the main power supply goes off.

Jul 2, 2013 · Microchip's MCP7941X series of low-power real-time clocks (RTC) uses digital timing compensation for an accurate clock / calendar, a programmable output control for versatility, a power sense circuit that automatically switches to the backup supply, and nonvolatile memory for data storage.

NXP offers ultra-low-power RTCs that provide low power consumption enabling long battery life with regard to real-time clock functionality, as well as temperature compensated RTCs with integrated crystal CMOS optimized for very high accuracy and low power consumption for industrial applications.

Most modern RTCs reduce the number of pins required by supporting a serial interface. We offer a wide variety of highly accurate, low power, small package, and microelectromechanical systems (MEMS)-based real-time clocks to suit any of your solution needs.

Feb 9, 2020 · Real-time clocks (RTC) are timers dedicated to maintaining a one-second timebase. In addition, an RTC is often used to keep track of clock time and calendar date either in software or hardware. Many of the features of an RTC are very specialized and required for maintaining high accuracy and very reliable operation.

The MCP7940N series of low-power Real-Time Clocks (RTC) uses digital timing compensation for an accurate clock/calendar, a programmable output control for versatility, and a power sense circuit that automatically switches to the backup supply. Using a low-cost 32.768 kHz crystal, it tracks time using several internal registers.
