RV-3032-C7 is a high performance temperature compensated real-time clock module with I²C interface which offers the world’s best time accuracy across industrial temperature range at ultra-low current consumption at the size of a common clock crystal (3.2mm x 1.5mm).
This RTC module is ideal for applications requiring always-on timekeeping functions, with compliance to stringent clock accuracy over time, wide temperature range, and long battery life. It has been designed with smart metering and other similar industrial or consumer applications, such as wearables and IoT, in mind.
Thanks to its extremely low power consumption and power management features, including wide supply voltage range, automatic backup switch, versatile charge pump, and programmable trickle charger, this device can be coupled with a small sized, low capacity, rechargeable battery, or a low cost coin cell power unit. This reduces the overall dimensions and the manufacturing cost of the end product while optimizing the life of the battery.
