DS1337S Description

Short technical summary and product information.

The DS1337S is a low-power serial real-time clock (RTC) and calendar IC from Analog Devices / Maxim Integrated. It manages all timekeeping functions, including counting seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. The device includes two programmable time-of-day alarms and a programmable square-wave output, which defaults to 32kHz on power-up.

 

Designed for broad microcontroller compatibility, the DS1337S utilizes an I2C serial interface for data transfer. It operates with a supply voltage range of 1.8V to 5.5V, while timekeeping can be maintained with voltages as low as 1.3V. The operating temperature range is -40°C to +85°C, making it suitable for industrial applications.

 

This clock/calendar IC is available in an 8-SOIC surface-mount package. Its applications span various sectors, including handheld devices, consumer electronics, office equipment, medical devices, and telecommunications systems.
