DS1337C Description

Short technical summary and product information.

The DS1337C from Analog Devices / Maxim Integrated is a serial real-time clock (RTC) designed for low-power applications. It manages all timekeeping functions, including seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. The device features two programmable time-of-day alarms and a programmable square-wave output, defaulting to 32kHz on power-up.

 

This RTC interfaces with most microcontrollers via an I2C serial interface. It operates within a voltage range of 1.8V to 5.5V, with timekeeping maintained as low as 1.3V. The device is housed in a 16-SOIC surface-mount package, measuring 7.50mm in width, and operates across an industrial temperature range of -40°C to +85°C.

 

Applications for the DS1337C include handheld devices like GPS and POS terminals, consumer electronics such as set-top boxes, office equipment like fax machines and printers, medical devices including glucometers, and telecommunications equipment like routers and servers. Its integrated features and compact package make it suitable for a wide array of embedded systems requiring accurate timekeeping.
