RV-3049-C3- Real Time Clocks - Modules

Real Time Clock Module with SPI-Bus - Ultra-Low Power

General Description

The RV-3049-C3 is an ultra-miniature Real-Time-Clock Module with embedded Crystal. This RTC has an SPI Bus (4-wire Serial-Interface) and offers temperature compensated time. The STC-Smart Temperature Compensation is calibrated in the factory and leads to a very high time-accuracy of ± 6ppm from -40°C to +85°C and ± 8ppm from -40°C to +125°C.

Beside standard RTC functions, it includes a Backup- Battery Input with internal switchover function, a programmable Trickle-charge circuitry, an integrated Temperature Sensor with digital-output and offers 8 Bytes RAM and 2 Bytes EEPROM for customer's application.

The calendar function tracks year and leap-year flags. The clock tracks second, minute and hour in 24-hour format. Programmable alarm setting and universal timer functions increase flexibility.

For pick-and-place equipment, the parts are available in 12 mm tape: 7" (178 mm) reel with 1'000 parts or reel with 3'000 parts.
