The Renesas Electronics Corporation X1227S8-2-7A is a Clock/Calendar IC featuring an I2C, 2-Wire Serial interface. This device operates within a voltage range of 2.7V to 5.5V for the main supply and 1.8V to 5.5V for battery backup. It offers essential timekeeping functions, including clock and calendar tracking with support for YY-MM-DD-dd date format and HH:MM:SS (12/24 hr) time format. Key features include alarm functionality, leap year compensation, supervisor capabilities, and a watchdog timer, contributing to robust system monitoring. Timekeeping current is typically between 10µA and 20µA at 2.7V to 5V. The component is housed in an 8-SOIC (0.154", 3.90mm Width) package, designed for surface mounting. Typical applications span industrial automation, consumer electronics, and automotive systems where precise timekeeping and system supervision are critical.
