MAX6901ETA-T

Real Time Clock Overview

The MAX6901ETA-T is a real-time clock (RTC) integrated circuit designed for accurate timekeeping and calendar functions in embedded systems. It features a 3-wire serial interface and operates within a supply voltage range of 2V to 5.5V. The device supports both 12-hour and 24-hour time formats, along with YY-MM-DD date formatting. It includes alarm capabilities, leap year correction, and Y2K compliance. The component draws a maximum current of 1.05µA at 2V and 4.2µA at 5V during timekeeping. It is housed in an 8-WDFN package with an exposed pad and is rated for operation between -40°C and +85°C.
