DS138833 Description

Short technical summary and product information.

The DS1388Z-33+T&R, also known as DS138833, is a Real Time Clock (RTC) integrated circuit manufactured by Analog Devices (formerly Maxim Integrated). This component utilizes an I2C (2-wire serial) interface for communication and includes a clock/calendar function. It is equipped with 512 bytes of memory and supports features such as leap year calculation, a watchdog timer, a supervisor function, and a trickle-charger. The device operates within a supply voltage range of 2.97V to 3.63V and a battery supply range of 1.3V to 5.5V. The timekeeping current consumption is a maximum of 150µA at the specified supply voltage. The operating temperature range for this IC is -40°C to 85°C. It is housed in an 8-SOIC surface-mount package with specific dimensions of 0.154" (3.90mm) width. The DS138833 is suitable for applications requiring accurate timekeeping and calendar functions within embedded systems.
