Real-Time Clock (RTC) ICs

ST offers the widest portfolio of real-time clock (RTC) ICs including ultra-low-power devices, the world’s smallest package with embedded crystal, ST’s SNAPHAT® battery with crystal integrated.  

We offer more interface options and more value-added features, such as supervisory functions that include alarm, battery switchover, reset and special features with time stamp, anti-tamper for secure applications, audio, and trickle charge.

ST's removable/replaceable SNAPHAT® battery top contains a Lithium coin cell battery and a 32KHz crystal.  It is compatible with all of ST's real-time clocks in the surface mount SOH-28 and SOH-44 packages.

Real-time clock for demanding wearable devices

ST’s M41T62LC6F real-time clock is the perfect match for wearable devices when size, weight, and power-efficiency matters.

It offers a very low frequency error at 25 °C which equates to about 5 seconds per month, an ultra-low power consumption of 350 nA in standby, and comes in an ultra-small 1.5 x 3.2 mm package with an embedded crystal oscillator.
