X1227V8-2.7A

Overview

The X1227V8-2.7A is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation. It provides timekeeping functions including clock/calendar, alarms, leap year compensation, and watchdog timer capabilities. The device supports I2C and 2-wire serial interfaces for communication. It operates with a supply voltage range of 2.7V to 5.5V and features low current consumption of 10µA to 20µA at 2.7V to 5V. The component is housed in an 8-SOIC package with a width of 3.90mm and is rated for industrial temperatures from -40°C to 85°C.

Feature Summary

• Integrated Real-Time Clock with Calendar functionality
• Supports I2C and 2-Wire Serial Interfaces
• Includes Alarm, Leap Year, Monitor, and Watchdog Timer features
• Operates within 2.7V to 5.5V supply voltage range

Applications

• Industrial control systems requiring precise timekeeping
• Data logging equipment needing calendar tracking
• Embedded devices utilizing I2C communication protocols

Procurement Notes

Verify the specific suffix 'A' against official Renesas documentation to confirm if it denotes a specific tape-and-reel packaging variant or a minor revision change, as suffixes can impact handling and storage requirements. Confirm end-of-life status through authorized distributors, as this model may be discontinued. Ensure compliance with RoHS3 standards if required by the target application environment.

Selection Notes

Select this component when an I2C-compatible RTC with low power consumption is required for space-constrained designs using an 8-SOIC package. Compare against the X1227S8IZ-2.7 for pinout compatibility if switching packages. Verify that the 2.7V minimum operating voltage aligns with the system's battery or backup power supply characteristics during brown-out conditions.

Part Context

This part belongs to the X1227 series of real-time clocks from Renesas. It shares functional similarities with the X1228 series but differs in package options and interface configurations. The X1227V8-2.7A specifically targets applications requiring standard SOIC footprint integration while maintaining the core timing and alarm features found across the family.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided source data. Evaluate the X1227S8IZ-2.7 for potential pin-to-pin compatibility if the SOIC package constraint remains unchanged.
