It tracks time in HH:MM:SS (12 or 24 hour) and date in YY-MM-DD-dd format, with built-in alarm, daylight savings, and leap year handling — no firmware math for February 29th. ## Supply voltage, battery backup, and timekeeping current Timekeeping current is 14 µA to 15 µA max at 3 V to 5 V — low enough that a CR2032 coin cell with 225 mAh capacity theoretically backs it up for over a year, though self-discharge and the alarm pull-down will reduce that in practice.","metaTitle":"Renesas ISL12022MIBZ RTC Clock/Calendar I2C 20-SOIC","metaDescription":"Renesas ISL12022MIBZ RTC, Clock/Calendar, I2C interface, 128B SRAM, 2.7V-5.5V supply, -40°C to +85°C, 20-SOIC.
