ISL12030IBZ

Real Time Clock Overview

The ISL12030IBZ is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics, formerly Intersil. It features an I2C serial bus interface and includes 128 bytes of non-volatile EEPROM for data storage. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports date formats including day-of-week, month, day, and year, alongside standard HH:MM:SS timekeeping. It is housed in an 8-lead SOIC package and functions without battery backup switching. The component is rated for industrial temperatures from -40°C to +85°C.

Real Time Clock Feature Summary

• Integrated 128-byte EEPROM for user data retention
• I2C serial bus interface for communication
• No battery backup switching mechanism required
• Industrial temperature range (-40°C to +85°C)

Real Time Clock Applications

• Data logging systems requiring timestamping
• Embedded devices needing precise timekeeping
• Industrial equipment with I2C connectivity

Real Time Clock Procurement Notes

Verify the manufacturer designation as Renesas Electronics, as Intersil was acquired. Confirm the specific suffix 'IBZ' corresponds to the SOIC-8 package and lead-free compliance status via the official datasheet. Ensure the design accounts for the absence of automatic battery backup switching if continuous operation during main power loss is critical.

Real Time Clock Selection Notes

Select this component when an RTC with integrated non-volatile memory is required on an I2C bus. Compare against the ISL12022IBZ if calendar compensation or different backup switching behaviors are needed. Verify that the 128-byte EEPROM capacity meets application storage requirements and that the 2.7V to 5.5V supply range aligns with the system power rails.

Real Time Clock Part Context

This part belongs to the ISL12030 series of real-time clocks. It shares the same core RTC functionality and package type as other variants in the family but is distinguished by its specific EEPROM integration and lack of battery backup switching features compared to related models like the ISL12022.

Real Time Clock Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with the ISL12022IBZ only if functional differences regarding backup switching and temperature compensation are acceptable.
