X1288S16I-2.7AT1

Overview

The X1288S16I-2.7AT1 is a Real-Time Clock/Calendar integrated circuit manufactured by Renesas Electronics Corporation. It tracks time in hours, minutes, seconds, and hundredths of a second, along with day of the week, day, month, and year. The device features an I2C interface for communication and is housed in a 16-SOIC package (0.295", 7.50mm width). It operates within a supply voltage range supported by the 2.7V suffix designation.

Feature Summary

• Tracks real-time clock data including hours, minutes, seconds, and hundredths of a second
• Maintains calendar information such as day of the week, date, month, and year
• Utilizes an I2C serial interface for system communication
• Designed for low-power operation during timekeeping functions

Applications

• Systems requiring precise time and date tracking
• Data logging equipment needing timestamp capabilities
• Embedded devices with power management requirements

Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Renesas Electronics Corporation. Procurement must rely on remaining stock from authorized distributors or secondary market sources. Verify authenticity and condition carefully due to end-of-life status. Check for available substitute part numbers if new production is required.

Selection Notes

Select this component only if legacy compatibility is mandatory. The 16-SOIC package and I2C interface define integration constraints. Consider the low standby current consumption for battery-backed applications. Evaluate alternative active components if design flexibility allows, as this part is discontinued.

Part Context

The X1288 series represents Renesas' line of real-time clock/calendar ICs. This specific model integrates timekeeping and calendar functions into a single chip with I2C connectivity. It is designed for applications where accurate time tracking is critical without requiring complex microcontroller overhead.

Replacement Considerations

Official substitutes are not explicitly listed in the provided documentation. Users should consult Renesas for cross-reference recommendations or evaluate compatible RTC ICs with similar I2C interfaces and package dimensions.
