DS138833 Description

Short technical summary and product information.

The DS1388Z-33+T&R, also known as DS138833, is a Real Time Clock (RTC) and clock/calendar integrated circuit manufactured by Maxim (Analog Devices). This component utilizes an I2C (2-wire serial) interface for communication.

 

Key features include 512 bytes of memory, support for leap years, a watchdog timer, a supervisor function, a trickle-charger, and integrated EEPROM. It operates within a supply voltage range of 2.97V to 3.63V and has a separate battery supply range of 1.3V to 5.5V. The maximum timekeeping current consumption is 150µA at the specified supply voltage.

 

This RTC IC is housed in an 8-SOIC surface-mount package with specific dimensions of 0.154" (3.90mm) width. The operating temperature range is from -40°C to 85°C, making it suitable for various environmental conditions. The time format can be displayed in either 12-hour or 24-hour format (HH:MM:SS:hh), and the date format is YY-MM-DD-dd.
