Manufacturer:NXP Description:The low-voltage serial-peripheral interface (SPI™) DS1390/DS1391 and the low-voltage 3-wire DS1392/ DS1393 real-time clocks (RTCs) are clocks/calendars that provide hundredths of a second, seconds, min- utes, 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 an AM/PM indicator. One programmable time-of-day alarm is provided. A temperature-compensated voltage reference monitors the status of VCC and automatically switches to the backup supply if a power failure is detected. On the DS1390, a single open-drain output provides a CPU interrupt or a square wave at one of four selectable fre- quencies. The DS1391 replaces the SQW/INT pin with a RST output/debounced input. The DS1390 and DS1391 are programmed serially through an SPI-compatible, bidirectional bus. The DS1392 and DS1393 communicate over a 3-wire serial bus, and the extra pin is used for either a separate interrupt pin or a RST output/debounced input. All four devices are available in a 10-pin µSOP package, and are rated over the industrial temperature range. |
