Real-Time-Clock with calendar, timer and alarm functions.
Overview
The RTC-32k-CAL.01 is a low power RTC relying on a crystal oscillator and designed to achieve the requirements of low power modes and deep sleep modes of IoT devices. Together with the qOSC-XTAL-LP- 32k-co.01 it will allow you to achieve the lowest power consumption for your Always-On domain.
Key Features
- Low power consumption: Designed to be used together with the qOSC-XTALLP-32k-co.01 crystal oscillator, a 60 nA oscillator, contributing to reach the lowest power consumption for the whole Always-On domain.
- High accuracy: A digital trimming logic enables to correct the inaccurate clock sources
- Available programmable functions : calendar, alam, timer
