RV-8063-C8-32.768KHZ-20PPM-TA-QA

Real Time Clock Overview

The RV-8063-C8-32.768KHZ-20PPM-TA-QA is a hermetically sealed SMD Real-Time Clock Module by Micro Crystal AG, integrating a CMOS circuit with a 32.768 kHz tuning fork crystal in a 2.0 x 1.2 x 0.70 mm ceramic package. It features a 3-wire SPI interface operating up to 7 MHz and provides timekeeping for year, month, date, weekday, hours, minutes, and seconds with automatic leap year calculation (2000–2099). The module operates on a supply voltage of 0.9 V to 5.5 V, consuming 190 nA at 3 V during timekeeping. It offers ±20 ppm accuracy at 25°C, user-programmable offset compensation, and AEC-Q200 automotive qualification.

Real Time Clock Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current documentation before procurement. The 'TA' suffix indicates the standard -40 to +85°C temperature range, while 'QA' denotes Automotive Grade AEC-Q200 qualification. Confirm that the required quantity matches the reel packaging options (e.g., 1,000 or 3,000 pcs) specified in the official ordering information to ensure correct fulfillment.

Real Time Clock Selection Notes

Select this module when a compact, low-profile RTC with SPI connectivity is required. The 2.0 x 1.2 x 0.70 mm footprint suits space-constrained designs. Ensure the system supports the 3-wire SPI protocol and can handle the 7 MHz interface speed. The wide voltage range (0.9 V–5.5 V) allows compatibility with various logic levels without additional level shifting in many cases.

Real Time Clock Part Context

This component belongs to the RV-8063-C8 series of Real-Time Clock Modules. The part number structure defines the product type (RV-8063), package size (C8: 2.0 x 1.2 x 0.70 mm), temperature range (TA), and qualification (QA). It is designed as a miniature, cost-effective solution for high-volume applications requiring precise timekeeping in harsh environments.

Real Time Clock Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. When evaluating alternatives, verify that the replacement maintains the same SON-8 footprint, SPI interface compatibility, and hermetic sealing requirements.
