ISL12029AIB27Z

Real Time Clock Overview

The ISL12029AIB27Z is a Real-Time Clock (RTC) and calendar integrated circuit manufactured by Renesas Electronics under the Intersil brand. It features an I2C bus interface for communication, supporting date formats of YY-MM-DD-day-of-week and time formats of HH:MM:SS in 24-hour mode. The device includes 512 bytes of EEPROM storage capacity and utilizes backup switching for power management. It operates within a supply voltage range of 2.7 V to 5.5 V and functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a 14-pin SOIC package.

Real Time Clock Feature Summary

• I2C Bus Interface for serial data communication
• Integrated 512 B EEPROM for non-volatile data storage
• Hardware backup switching capability for continuous operation during power loss
• Industrial temperature range support (-40°C to +85°C)

Real Time Clock Applications

• Data logging systems requiring precise timestamping
• Industrial control equipment needing reliable timekeeping
• Consumer electronics with calendar and alarm functionalities

Real Time Clock Procurement Notes

Verify current availability status as distribution channels may indicate limited stock or end-of-life conditions. Confirm RoHS compliance details directly with the manufacturer or authorized distributors before procurement. Ensure the specific suffix 'B27Z' matches the required packaging and material specifications for your assembly process.

Real Time Clock Selection Notes

Select this component when an I2C-compatible RTC with significant onboard EEPROM storage is required. The 14-pin SOIC package suits surface-mount applications. Verify that the system design supports the 2.7 V to 5.5 V operating voltage range and accommodates the backup switching mechanism for uninterrupted timekeeping.

Real Time Clock Part Context

This part belongs to the ISL12029 series of real-time clocks. It shares core functionalities with other variants in the family but is distinguished by its specific package type and suffix codes indicating manufacturing attributes. It serves as a drop-in replacement for similar Intersil/Renesas RTCs within the same operational constraints.

Real Time Clock Replacement Considerations

Check for direct pin-to-pin compatible alternatives within the ISL12029 series or newer Renesas RTC families. Verify if updated packages or enhanced feature sets are available in successor models while maintaining I2C compatibility.
