DS1340C-33# Description

Short technical summary and product information.

The DS1340C-33# is a Real Time Clock (RTC) and calendar IC from Analog Devices / Maxim Integrated, designed for accurate timekeeping functions. It features an I2C interface for serial communication with microcontrollers, making integration into various systems straightforward.

 

This device supports a wide operating voltage range from 1.3V to 5.5V and consumes a low current of 150µA at 5.5V, making it suitable for battery-backed applications. The operating temperature range is -40°C to 85°C, ensuring reliable performance in diverse environmental conditions.

 

Key features include leap year calculation and trickle-charge capability. The DS1340C-33# provides time in HH:MM:SS (24-hour format) and date in YY-MM-DD-dd format. It is supplied in a 16-SOIC package with a surface mount type, suitable for space-constrained designs.

 

This RTC is an enhanced second source for the ST M41T00, offering functional equivalence and compatibility. Its automatic power-fail detect and switch circuitry ensures continuous timekeeping during power interruptions.
