The ISL12020MIRZ-T is an extremely small, low-power, serial real-time clock (RTC) with an embedded crystal oscillator. Nicknamed \'MicroRTC\', the ISL12020MIRZ-T is designed to provide precision timekeeping in a wide range of applications.

The ISL12020MIRZ-T is highly versatile, supporting single-byte (I2C) and triple-byte (SPI, FIFO) instructions for all clock functions, as well as on-board 8-bit RAM, event control, and temperature-controlled auto calibration. The MicroRTC operates from a wide supply voltage range (1.2V - 3.6V) and offers very low power operation (1.1-3.3 VDC down to 400nA; 1.8-3.6 VDC down to 230nA). The ISL12020MIRZ-T features a host of features that make it ideal for a variety of applications, including battery-backed systems, industrial timing and remote sensing, telecom exchange synchronization and network clocks, as well as programs that require frequent and accurate timekeeping.

The ISL12020MIRZ-T makes use of a temperature-controlled oscillator, known as a "\'temperature-compensated crystal oscillator" (TCXO). The TCXO maintains accurate and reliable timekeeping performance independent of the surrounding environmental temperature. Additionally, the MicroRTC includes a programmable auto calibration function that monitors the clock accuracy and adjusts the oscillator frequency over time to ensure maximum accuracy. This feature is essential for applications that have frequent temperature variations over time.

The MicroRTC contains a 32kHz crystal, a 32kHz internal oscillator and a 32kHz temperature-compensated oscillator. This enables the device to accurately track time and provide a high degree of accuracy and reliability. Additionally, the MicroRTC has an extremely low power consumption, features a 5-times programmable frequency scaling function and a 17-year leap year calendar. This makes it an ideal solution for applications where power consumption is a major factor.

The ISL12020MIRZ-T is a highly reliable and versatile real-time clock, with an extremely low power draw and a robust design. It offers a high degree of accuracy and reliability suitable for a wide range of clock applications such as battery-backed systems, industrial timing and remote sensing, telecom exchange synchronization and network clocks. With its temperature-controlled oscillator, the ISL12020MIRZ-T can maintain accurate timekeeping even in varying environmental temperatures, making it an ideal solution for any application that requires precise timekeeping.
