RV-3049-C3-TA-QC-OPT A

Real Time Clock Overview

The RV-3049-C3-TA-QC-OPT A 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 1.3 V to 5.5 V for timekeeping and 1.8 V to 5.5 V for temperature compensation. Current consumption is typically 1000 nA at 3 V. The device includes 8 bytes of RAM, 2 bytes of EEPROM, a backup battery input with internal switchover, and a programmable trickle charger. It operates within a -40°C to +85°C temperature range.

Real Time Clock Feature Summary

SPI Bus Interface (4-wire serial)
Factory-calibrated STC-Smart Temperature Compensation
Embedded Crystal with ±6 ppm deviation from -40°C to +85°C
Integrated Temperature Sensor with digital output

Real Time Clock Procurement Notes

Verify the complete part number including the 'OPT A' suffix when ordering to ensure the calibrated version is received. Confirm the delivery form matches requirements, as this specific variant is available in 12 mm tape on a 7-inch reel containing 1,000 parts. Contact the manufacturer directly for alternative packaging options not listed in standard availability.

Real Time Clock Selection Notes

Select Option A over Option B if higher accuracy is required across the operating temperature range. Option A maintains a maximum deviation of ±6 ppm from -40°C to +85°C, whereas Option B allows up to ±25 ppm. Ensure the application voltage meets the minimum 1.8 V requirement if utilizing the temperature compensation features.

Real Time Clock Part Context

This component belongs to the RV-3049 family of real-time clock modules manufactured by EM Microelectronic-Marin SA. The C3 designation indicates the SMD ceramic package type. The TA suffix specifies the -40°C to +85°C operating temperature range, distinguishing it from the TB variant which supports extended temperatures up to +125°C.
