The DS1347T+T&R is an SPI-compatible real-time clock (RTC) and calendar IC manufactured by Analog Devices / Maxim Integrated. It manages all timekeeping functions, including seconds, minutes, hours, day of the week, date, month, year, and century. The device supports both 12-hour and 24-hour formats with an AM/PM indicator and includes a programmable time/date alarm function.
Key features include leap-year compensation and 31 x 8 bits of static RAM for scratchpad data storage. It operates over a wide voltage range of 2V to 5.5V and consumes low power, with a timekeeping current of 400nA at 2V. The interface is SPI, supporting speeds up to 4MHz at 5V. The DS1347T+T&R is available in an ultra-small 8-pin TDFN package (3mm x 3mm x 0.8mm), making it suitable for space-constrained applications.
This RTC is designed for applications such as point-of-sale equipment, intelligent instruments, fax machines, battery-powered products, and portable instruments. It uses a standard 32.768kHz watch crystal and requires no external crystal bias resistors or capacitors. The device operates within an industrial temperature range of -40°C to +85°C.
The operating voltage range is 2V to 5.5V.
The operating temperature range is -40°C to +85°C.
The DS1347T+T&R is available in an 8-TDFN (3x3) package.
Key features include Alarm, Leap Year compensation, and 31 x 8-bit SRAM.
The DS1347T+T&R uses an SPI interface.
The timekeeping current at 2V is 400nA.
