The RTC tracks time in HH:MM:SS format (12/24 hr selectable) and date in YY-MM-DD-dd format, covering the full calendar with leap-year handling. The 2-byte SRAM retains data as long as the main or battery supply is present. ## Supply range and timekeeping current Timekeeping current draw is 4 µA to 6 µA maximum at 3 V to 5 V, which keeps the RTC alive on a coin cell for years when the main rail is off.","metaTitle":"ISL1208IB8Z Renesas RTC Clock/Calendar I²C 8-SOIC","metaDescription":"ISL1208IB8Z Renesas RTC Clock/Calendar, I²C interface, 2.7-5.5V supply, -40°C to +85°C, 8-SOIC.
