ISL12024IRTCZ

Real Time Clock Overview

The ISL12024IRTCZ is a Real-Time Clock (RTC) manufactured by Renesas Electronics, formerly Intersil. It features an I2C bus interface and provides date and time information in YY-MM-DD-dd and HH:MM:SS (24 hr) formats respectively. The device includes 512 bytes of EEPROM for data storage and supports alarm, calendar, clock, and interrupt functions. It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in an 8-lead TDFN package. The component is rated for industrial temperatures from -40°C to +85°C.

Real Time Clock Feature Summary

• Integrated 512-byte EEPROM for non-volatile data storage
• I2C serial bus interface for communication
• Built-in alarm, calendar, clock, and interrupt capabilities
• Backup switching support for continuous operation

Real Time Clock Applications

• Industrial control systems requiring precise timekeeping
• Data logging equipment with memory requirements
• Consumer electronics needing calendar functionality
• Telecommunications infrastructure timing modules

Real Time Clock Procurement Notes

The ISL12024IRTCZ is listed as an End-of-Life (EOL) product by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and alternative sourcing options is required before procurement planning.

Real Time Clock Selection Notes

Select this component when an I2C RTC with integrated EEPROM is necessary. Ensure the system design accommodates the 2.7V to 5.5V operating voltage range and the TDFN-8 package footprint. Verify that the required temperature range of -40°C to +85°C meets application specifications.

Real Time Clock Part Context

This part belongs to the ISL12024 series of real-time clocks. It shares functional similarities with other Intersil/Renesas RTCs like the ISL1208, but distinguishes itself through the inclusion of 512 bytes of EEPROM, whereas simpler models may offer only minimal backup registers.

Real Time Clock Replacement Considerations

Due to the EOL status, direct substitutes should be sought from the Renesas portfolio. Consider the ISL12027 series or newer RTC families with similar I2C interfaces and EEPROM capacities. Verify pin compatibility and software register mapping for seamless integration.
