RTC-Modul RV-3032-C7 from MICRO CRYSTAL

Extremely high time accuracy with an extremely low current consumption of only 160 nA:
manufacturer MICRO CRYSTAL offers this feature with the new high-performance RTC module RV-3032-C7.

This module is suitable for all applications that must precisely fulfil the following requirements:
greatest accuracy over a long period of time, with a simultaneously wide temperature range and a long battery life.

Uses include, for example, applications in the areas of smart metering, wearables, IoT and comparable industrial or consumer applications.

For the smallest applications
This module also sets new standards in miniaturisation.
It requires only half the space of a uSOP-8 housing.
The integrated energy management function enables you to use a wide voltage range from 1.2 to 5.5 V. You can also connect a small capacitor, rechargeable battery and a button cell for buffering.

Many extras included
In addition to all standard RTC functions, the module contains several extra functions.
For example, you can secure data protection with a password or freely define the output frequency up to 52 MHz. A temperature threshold alarm and external event synchronisation function have also been integrated. The device is controlled by the I2C interface.
