MCP79521T-I/MS, Real Time Clock SPI GP RTCC 2Kb EE 64B SRAM EUI-48

Real-Time Clocks Microchip Real-Time Clocks are offered from basic low-cost devices to various mid-range devices. These highly integrated devices have 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 I2C and SPI RTCCs, various applications can be supported with fewer features and lower performance.
