Real Time Clock datasheet and documents for RV-3049-C3-TB-QA-OPT B

RV-3049-C3-TB-QA-OPT B

Real Time Clock Overview

The RV-3049-C3-TB-QA-OPT B is an ultra-miniature Real-Time-Clock module featuring an embedded crystal and SPI interface. It provides temperature-compensated timekeeping with a supply voltage range of 1.8 V to 5.5 V for active compensation. The device includes 8 bytes of RAM, 2 bytes of EEPROM, and a programmable trickle charger. It supports calendar tracking, alarms, and universal timers. Time deviation is ±30 ppm from -40°C to +125°C (Option B). Current consumption is typically 1 µA at 3 V.

Real Time Clock Procurement Notes

Verify the complete part number when ordering. This specific variant is available in a 12 mm tape on a 7-inch reel containing 1,000 parts. Ensure compatibility with the extended operating temperature range (-40°C to +125°C) and Option B accuracy specifications.

Real Time Clock Selection Notes

Select this model for applications requiring high accuracy over a wide temperature range using an SPI bus. Compare Option A (±8 ppm) if tighter tolerance is needed. Verify package dimensions (5.0 x 3.2 x 1.2 mm) fit the PCB layout. Check power requirements against the 1.8 V minimum for temperature compensation.

Real Time Clock Part Context

The RV-3049-C3 belongs to EM Microelectronic's family of ultra-miniature RTC modules. It integrates a ceramic SON 10-pin package with an embedded crystal. The 'TB' suffix indicates the extended temperature range, while 'QA' denotes the SPI interface and Option B calibration level.
