RV-3129-C3

Product catalog summary

Overview: The RV-3129-C3 is an ultra-miniature Real-Time Clock (RTC) module with an embedded crystal, featuring an I2C bus interface and temperature-compensated timekeeping. It is designed for high accuracy and reliability across a wide temperature range.

Specifications: The RTC offers a time accuracy of ±6ppm from -40°C to +85°C and ±8ppm from -40°C to +125°C. It includes a backup battery input with an internal switchover function, programmable trickle-charge circuitry, an integrated temperature sensor with digital output, 8 bytes of RAM, and 2 bytes of EEPROM.

Features: The module supports standard RTC functions, including a calendar with year and leap-year tracking, a 24-hour clock format, programmable alarms, and universal timer functions. It is automotive qualified according to AEC-Q200 Rev. C.

Options:

Option A (Calibrated): Offers precise time deviation across various temperature ranges, with a maximum deviation of ±0.70 s/day at -40°C to +125°C.
Option B (Default): Provides a broader range of time deviation, with a maximum of ±2.60 s/day at -40°C to +125°C.

Environmental Characteristics: The module operates within a temperature range of -40°C to +125°C and can withstand shock resistance of 5000 g and vibration resistance of 20 g.

Electrical Characteristics: At 25°C, the supply voltage ranges from 1.3V to 5.5V for timekeeping and 1.8V to 5.5V for temperature compensation. Current consumption is between 800 to 1000 nA at 3V.

Package and Processing: The module is available in a SON 10-pin package suitable for SMD mounting, with Au plated pads and reflow soldering at 260°C for a maximum of 20 seconds.

Pin Connections: The module includes connections for CLK Output Enable, Supply Voltage, Clock Output, Serial Clock Input, Serial Data, Ground, Interrupt Output, and Backup Supply Voltage.

Real Time Clock Module with I2C-Bus DIMENSIONS Package: Extremely Accurate RTC Module with embedded Xtal. I2C Interface Temperature Compensation Automotive qualified, according to AEC-Q200 Rev. C Option A: Temperature Time Deviation @ +25°C ± 0.26 s/day ± 0°C to +50°C ± 0.35 s/day ± -10°C to +60°C ± 0.44 s/day ± -40°C to +85°C ± 0.52 s/day ± -40°C to +125°C ± 0.70 s/day ± 100% leadfree, RoHS - compliant DESCRIPTION: The RV-3129-C3 is an ultra miniature Real-Time-Clock Module with embedded Crystal. This RTC has an I2C Bus (2-wire SerialInterface) 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'
