X1288S16IT1

Overview

The X1288S16IT1 is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation. It combines RTC, calendar, CPU supervisor, and EEPROM functionalities into a single device. The component operates within a temperature range of -40°C to +85°C and utilizes a 16-SOIC surface-mount package with a width of 7.50mm. It features an I2C interface for communication.

Feature Summary

• Tracks time including hours, minutes, seconds, and hundredths of a second
• Maintains calendar data such as day of the week, date, month, and year
• Integrates CPU supervisor functionality for system monitoring
• Includes embedded EEPROM for non-volatile data storage

Applications

• Real-time clock and calendar tracking in electronic systems
• CPU supervision and reset management
• Non-volatile data storage applications requiring EEPROM integration

Procurement Notes

Verify the specific suffix IT1 against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with I2C bus voltage levels and check for any obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a combined solution for timekeeping, system supervision, and data storage is required. The choice depends on the need for a single-chip implementation that reduces board space compared to discrete components. Verify interface compatibility and environmental operating ranges match the target application requirements.

Part Context

This part belongs to the X1288 series of real-time clocks. It is designed for applications needing precise timekeeping alongside system monitoring capabilities. The integration of EEPROM allows for storing configuration data or logs without external memory chips, simplifying the overall system architecture.
