The X1288V14IT1 is a Real-Time Clock (RTC) and Calendar integrated circuit manufactured by Renesas Electronics Corporation. It operates via an I²C bus interface and supports both 12-hour and 24-hour time formats. The device provides date tracking including leap year compensation, with a format of YY-MM-DD-day. It features a low-power battery backup input allowing operation at voltages between 1.8V and 5.5V, while the main supply ranges from 4.5V to 5.5V. The component is housed in a 14-TSSOP surface-mount package and is rated for commercial operating temperatures from 0°C to 70°C.
Verify the specific suffix 'IT1' against official Renesas documentation to confirm tape-and-reel packaging and temperature grade. Confirm current availability status as older RTC variants may be subject to discontinuation or last-time-buy notices.
Select this component when an I²C-connected RTC with calendar capabilities and low standby power is required. Ensure the system design accommodates the 4.5V–5.5V VCC range and provides a separate battery input for continuous timekeeping during main power loss.
This part belongs to the X1288 family of real-time clocks. It shares functional similarities with other Renesas RTCs but is distinguished by its specific voltage requirements, package type, and integration of supervisor/watchdog features within a compact TSSOP form factor.
Cross-reference with other Renesas X1288 variants or compatible I²C RTCs such as the DS1307 series if pinout compatibility allows. Verify register mapping and voltage levels before substitution.
