MAX6917EO50+

Real Time Clock Overview

The MAX6917EO50+ is a Real-Time Clock (RTC) IC manufactured by Analog Devices Inc./Maxim Integrated. It integrates clock, calendar, and supervisory functions within a single component. The device features a 20-SSOP package with a width of 0.154 inches (3.90 mm). It operates on a supply voltage range of 2.7V to 3.3V and supports an industrial temperature range from -40°C to +85°C. Communication is handled via an I2C interface using two-wire serial protocols. The internal memory provides 96 bytes of storage capacity for data retention.

Real Time Clock Feature Summary

• Integrated RTC with clock, calendar, and microprocessor supervisor functions
• I2C compatible two-wire serial interface
• 96-byte non-volatile RAM storage capacity
• Operates within 2.7V to 3.3V supply voltage range

Real Time Clock Applications

• Systems requiring precise timekeeping and calendar tracking
• Embedded devices needing integrated power supervision
• Industrial equipment operating in extended temperature environments

Real Time Clock Procurement Notes

This component is listed as obsolete or end-of-life. Availability is restricted, and it may not be sold in all regions. Verification of current stock status and alternative sourcing channels is required before procurement planning.

Real Time Clock Selection Notes

Select this part when a combined RTC and supervisor solution is needed in a 20-pin QSOP/SSOP package. Ensure the system design supports the 2.7V to 3.3V operating voltage and utilizes an I2C bus. Verify that the 96-byte SRAM meets the specific data logging requirements.

Real Time Clock Part Context

The MAX6917 series includes variants such as the MAX6917EO30+. These parts are part of the Maxim Integrated portfolio now under Analog Devices. They serve as integrated solutions for timekeeping and system monitoring in compact form factors.

Real Time Clock Replacement Considerations

Check for direct pin-to-pin replacements within the MAX6917 family. Since the part is obsolete, evaluate newer RTCs with integrated supervisors from Analog Devices that offer I2C interfaces and similar package dimensions.
