Product Description

Perfect for cost-sensitive high volume applications where you need an all-in-one solution to help with space saving and procurement costs, the RV-4162-C7 with I2C bus interface has a tiny 3.2 x 1.5mm footprint package.

This uncompensated RTC module has good frequency tolerance of ±10ppm at 25ºC and comes with operating temperature range of -40 to +85ºC as standard. The RV-4162-C7 also features standard 24 hour clock functionality down to hundreths of seconds measurement. Standard calendar functionality includes date, month, year and century tracking with leap year compensation. This RTC also features alarm setting and a watchdog function.

In order to align ourselves with industry-standard nomenclature the name of this product has been revised from RV4162C7 to RV-4162-C7. There have been no changes to form, fit or function of the component. You can find more information in our product change notice PCN19032005321 here.
