Характеристики

DS1337S+, Часы реального времени с последовательным …The DS1337S+ is an I²C serial Real-time Clock with two programmable time-of-day alarms and a programmable square-wave output. Address and data are transferred serially through an I²C bus. The clock/calendar provides seconds, minutes, hours, day, date, month and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. The device is fully accessible through the serial interface while VCC is between 1.8 and 5.5V. I²C operation is not guaranteed below 1.8V. Timekeeping operation is maintained with VCC as low as 1.3V.

• Completely manages all timekeeping functions
• Interfaces with most microcontrollers
• Surface-mount package with an integrated crystal saves additional space and simplifies design
• Supports operation in a wide range of applications
