V3020SO8B+

Real Time Clock Overview

The V3020SO8B+ is a Real-Time Clock (RTC) integrated circuit manufactured by EM Microelectronic, housed in an 8-SOIC package. It provides clock/calendar functionality with a supply voltage range of 1.2V to 5.5V and operates within a temperature range of -40°C to +85°C. The device features a 3-wire serial interface for communication and includes alarm capabilities, leap year compensation, and onboard RAM. Its maximum current consumption during timing operations is specified at 0.8µA when powered at 5V.

Real Time Clock Feature Summary

• Integrated RTC with YY-MM-DD-dd date format and HH:MM:SS timekeeping
• Low power consumption of 0.8µA @ 5V
• Wide operating voltage range from 1.2V to 5.5V
• Includes alarm function, leap year correction, and user-accessible RAM

Real Time Clock Applications

• Battery-backed real-time clock systems
• Data logging devices requiring precise time stamping
• Embedded systems needing calendar and alarm functions

Real Time Clock Procurement Notes

Verify the specific suffix 'B+' against the manufacturer's official documentation to confirm pinout compatibility and feature set variations compared to standard versions. Note that the related part number V3020SO8A+ has been marked as End-of-Life (EOL) as of June 20, 2024; ensure the V3020SO8B+ is currently available and not subject to similar discontinuation notices before procurement.

Real Time Clock Selection Notes

Select this component for applications requiring a low-power, standalone RTC solution with minimal external components. Ensure the system design supports the 3-wire serial interface protocol. Verify that the required operating voltage falls within the 1.2V to 5.5V range and that the 8-SOIC package dimensions fit the PCB layout constraints.

Real Time Clock Part Context

The V3020 series represents EM Microelectronic's line of ultra-low power RTCs. The SO8B variant specifically denotes the 8-pin Small Outline Integrated Circuit package configuration. This family is designed for portable electronics where power efficiency and accurate timekeeping are critical, often replacing discrete crystal and oscillator circuits.

Real Time Clock Replacement Considerations

Check for direct pin-to-pin replacements within the V3020 family or other EM Microelectronic RTCs. Cross-reference with industry-standard RTC ICs if the V3020 series is unavailable, ensuring compatible voltage levels and interface protocols.
