A Feature-Rich, Low-Cost Timekeeping Solution

Microchip supports a wide range of Real-Time Clocks from basic low-cost devices to a variety of mid-range devices that are highly integrated with a usable amount of non-volatile memory and a combination of features that are very effective when operating within a single battery backed clock device. With, both I2C and SPI RTCCs available, various applications can be supported at a price that is lower than competitive devices with fewer features and lower performance.
