DS1340C-33#T&R Description

Short technical summary and product information.

The DS1340C-33#T&R is a Real-Time Clock (RTC) and calendar IC manufactured by Analog Devices / Maxim Integrated. It is designed to manage all timekeeping functions, counting seconds, minutes, hours, day, date, month, and year. This device offers a wide operating voltage range from 1.3V to 5.5V and consumes low power, extending battery backup run time.

 

Key features include an I2C, 2-Wire Serial interface for easy communication with microcontrollers, operating at speeds up to 400kHz. It also provides trickle-charge capability, an oscillator stop flag, and automatic power-fail detect circuitry that switches to a backup supply. The operating temperature range is -40°C to 85°C.

 

This RTC is supplied in a 16-SOIC surface-mount package, measuring 0.295 inches (7.50mm) in width. It is suitable for applications requiring accurate timekeeping, such as portable instruments, point-of-sale equipment, medical equipment, and telecommunications systems.
