MAX6916EO50+T

Real Time Clock Overview

The MAX6916EO50+T is a real-time clock (RTC) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a serial 3-wire or SPI interface and supports HH:MM:SS time format in 24-hour mode. The device includes calendar functionality, an alarm feature, and 96 bytes of non-volatile SRAM controlled via NV SRAM Control. It operates within a supply voltage range of 4.5 V to 5.5 V and functions at temperatures between -40°C and +85°C. The component is housed in a 20-pin QSOP package.

Real Time Clock Feature Summary

• Integrated RTC with calendar, clock, and alarm capabilities
• Serial 3-Wire or SPI bus interface for communication
• 96-byte NV SRAM storage capacity
• Operates on 4.5 V to 5.5 V power supply

Real Time Clock Applications

• Microprocessor-based systems requiring precise timekeeping
• Data logging equipment needing calendar tracking
• Alarm-enabled embedded devices

Real Time Clock Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly. Confirm current availability status as distribution channels may list this item as discontinued or limited stock. Ensure the 20-QSOP package dimensions match the target PCB footprint before procurement.

Real Time Clock Selection Notes

Select this part when a dedicated RTC with onboard NV SRAM is needed alongside standard SPI/3-wire compatibility. Verify that the system power rail remains stable between 4.5 V and 5.5 V. Consider the 20-QSOP package size constraints relative to other available RTC packages in the same family.

Real Time Clock Part Context

This component belongs to the MAX6916 series of real-time clocks. It shares core functionalities with variants like MAX6916EO30+, differing primarily in packaging or minor electrical specifications. The 'MAX6916' base model serves as the reference for the family's architectural features.

Real Time Clock Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source data. Evaluate other MAX6916 family members for pin-compatible alternatives if available through official manufacturer documentation.
