Product Description

Although no longer recommended for new designs, the RV-3049-C2 real time clock module with SPI bus interface does offer a range of excellent specifications and additional functionality for existing designs. Smart temperature compensation means this component is suitable for a wide range of applications, including external metering, with exellent temperature stability options available covering operating temperature ranges as wide as -40 to +125ºC.

RTC built-in functions include standard clock and calendar functions, with year tracking and leap-year flagging, and additional specialized functions include backup battery input with internal switchover function, programmable trickle-charge circuitry, integrated temperature sensor with digital output, and 8 bytes of RAM and 2 bytes of EEPROM. For new designs please consider the RV-3149-C3 which features the same functionality and specifications but within a smaller 3.7 x 2.5mm package and is more competitively priced.

In order to align ourselves with industry-standard nomenclature the name of this product has been revised from RV3049C2 to RV-3049-C2. 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.
