Maxim Integrated DS134x Low-Current SPI / 3-Wire RTCs

Maxim Integrated's DS134x low-current SPI / 3-wire real-time clocks (RTCs) are time-keeping devices compatible with any 32.768 kHz crystal. The ability of the DS134x to drive high ESR allows use of the smallest available surface mount crystals, saving board space. Maxim Integrated's DS134x RTCs also provide extremely low standby current, permitting longer life from a backup supply source. 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 24-hour or 12-hour format with an active-low AM/PM indicator. Address and data are transferred serially through an SPI or 3-wire interface. Two programmable time-of-day alarms are provided. Maxim Integrated DS134x RTCs are designed for use in embedded timestamping, handheld devices, medical equipment, and telematics applications.
