Procurement Notes

Verify the specific suffix 'AC-2SRGI' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with system I2C bus voltage levels before integration. Cross-reference part numbers carefully as suffixes often denote critical variations in packaging or operational specifications.

Selection Notes

Select this component when a dedicated RTC with I2C connectivity is required. Consider its alarm features for wake-up applications. Evaluate power consumption requirements against the device's low-power characteristics. Confirm that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the Renesas 1339 series of serial real-time clocks. These devices are designed for applications needing reliable time/date information with minimal microcontroller overhead. The series typically offers various package options and interface configurations to suit different design constraints.

Replacement Considerations

Check Renesas datasheets for direct pin-to-pin replacements within the 1339 family. Verify electrical parameters and interface compatibility before substituting. Generic RTCs may lack specific alarm or output features.
