V3020XSO8A+

Real Time Clock Overview

The V3020XSO8A+ is a Real-Time Clock (RTC) integrated circuit manufactured by EM Microelectronic. It provides clock/calendar functionality with a date format of YY-MM-DD-dd and time format supporting both 12-hour and 24-hour modes (HH:MM:SS:hh). The device features a 3-wire serial interface and includes 1 byte of RAM storage. Key specifications include a supply voltage range of 1.2V to 5.5V, a maximum current consumption of 7µA at 5V, and an operating temperature range of -40°C to 125°C. It is housed in an 8-SOIC package.

Real Time Clock Feature Summary

• Real-time clock/calendar IC with alarm, leap year, and RAM features
• 3-wire serial interface for communication
• Wide supply voltage range: 1.2V to 5.5V
• Operating temperature range: -40°C to 125°C

Real Time Clock Applications

• Clock/calendar systems requiring low power consumption
• Data logging devices needing timestamp capabilities
• Industrial equipment with wide temperature operation requirements

Real Time Clock Procurement Notes

The V3020XSO8A+ has been officially declared End-of-Life (EOL) as of June 20, 2024. Verification of availability should focus on remaining stock from authorized distributors or alternative sourcing channels, as the component is no longer in active production. Confirm RoHS3 compliance status if required for specific regulatory environments.

Real Time Clock Selection Notes

Select this component when a dedicated RTC with a 3-wire serial interface is required within a 1.2V to 5.5V supply range. Ensure the design accommodates the -40°C to 125°C industrial temperature grade. Note that due to the EOL status, long-term supply continuity cannot be guaranteed; consider functional equivalents if future production volume is anticipated.
