Real Time Clocks (RTC) are special timing circuits that keep track of the current time and date. The ISL12058IRTZ is a highly integrated RTC from Intersil that is designed for ultra-low current system monitoring, industrial and portable applications. Its low power consumption, versatile package and integrated timing accuracy makes it an ideal solution for a range of products.

ISL12058IRTZ Features and Specifications

The ISL12058IRTZ has several key features, making it an ideal choice for low-power timing applications. Its low power consumption can be as low as 89 nA, meaning it has a standby current that is much lower than common ICs. This makes the ISL12058IRTZ a great choice for portable and battery-powered applications, providing time and date accuracy while minimizing power consumption. Additionally, the integrated oscillator accuracy can be as high as 2ppm – making it ideal for timekeeping applications that require accuracy.

The ISL12058IRTZ also features comprehensive driver logic and interface functions, meaning it can interface with all common microcontrollers and digital signal processors. This lets the user easily configure the RTC to provide the required precision for their application. The RTC also has several different output mode choices and programmable alarm functions, allowing for greater flexibility and customization for their application.

The ISL12058IRTZ comes in an ultra-small, 2.6mm x 4.0mm 6-bump UDFN package, making it a perfect fit for space-constrained applications. Additionally, its operating temperature range is from -40°C to +85°C, making it suitable for a range of commercial and industrial applications.

ISL12058IRTZ Applications

Due to its low power consumption and accurate time-keeping capability, the ISL12058IRTZ can be used in a range of applications. These include portable and battery-powered applications, industrial automation, medical devices, and home electronic appliances.

Additionally, the ISL12058IRTZ can be used in any system that requires precision timing. These could include data monitoring and logging, industrial control systems, server clocks, and other time-sensitive applications.

ISL12058IRTZ Working Principle

The ISL12058IRTZ uses a quartz crystal oscillator to keep track of the current time. The oscillator has an integrated temperature-compensated oscillator (TCXO) circuit, which is used to provide a more accurate and stable timing signal. This signal is then passed to the main RTC counters and registers, where it is used to update the time and date information.

The ISL12058IRTZ also features an on-chip oscillator circuit, which is used to recalibrate the quartz crystal oscillator periodically. This ensures that the RTC can accurately count down the time and date with a minimal drift in accuracy. Additionally, the ISL12058IRTZ also features an adjustable current source that can be used to trim the crystal oscillator accuracy.

Conclusion

The ISL12058IRTZ is a highly integrated, low-power RTC from Intersil, designed for ultra-low power system monitoring, industrial, and portable applications. Its low power consumption, versatile package, and integrated timing accuracy make it an ideal choice for a range of products. Additionally, its comprehensive driver logic and interface functions allow it to easily be integrated with all common microcontrollers and digital signal processors.
