1 pcs : PCF85053ATKJ - Real Time Clock Bootable CPU RTC with dual I2C interface, 128-byte SRAM and alarm function

PCF85053A CMOS Real-Time Clock (RTC) NXP Semiconductors PCF85053A CMOS Real-Time Clock (RTC) is optimized for low power consumption and automatic switching to battery on primary power loss. The NXP Semiconductors PCF85053A features clock output, alert interrupt output, a 128-byte battery backed-up SRAM, and two I2C buses. Its clock output calibration-related registers set the PCF85053A apart from other RTCs, which allows for crystal capacitive load (CL) configuration and offset register setting.
