RV-3029-C3
RV-3029-C3 is Real Time Clock Module manufactured by EM Microelectronic.
Description
The RV-3029-C3 is an ultra-miniature Real-Time-Clock Module with embedded Crystal. This RTC has an I2C Bus (2-wire Serial-Interface) and offers temperature pensated time. The STC-Smart Temperature pensation 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
