DS1388Z-5+

The DS1388Z-5+ is an I2C RTC/supervisor with trickle charger and 512 bytes EEPROM in 8 pin NSOIC package. It provides a clock/calendar, programmable watchdog timer, power supply monitor with reset and 512 bytes of EEPROM. The clock provides hundredths of seconds, seconds, minutes and hours, it operates in 24hr or 12hr format with an AM/PM indicator. The calendar provides day, date, month and year information. The date at the end of month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. A watchdog timer provides a reset for an unresponsive microprocessor. It is programmable in 10ms intervals from 0.01 to 99.99 seconds. A temperature compensated voltage reference and comparator circuit monitors the status of VCC. If a primary power failure is detected device automatically switches to the backup supply and drives the reset output to the active state. It is used in point of sale equipment, network interface cards and wireless equipment.
