MAXIM INTEGRATED / ANALOG DEVICES DS174670 Real-Time Clock and Static RAM
The DS1746-70+ is a Y2K-compliant, non-volatile real-time clock and 128K x 8 static RAM in a 32-pin EDIP package. It features a full-function RTC with automatic leap year and month-length corrections, and user access via a byte-wide interface. The device's RTC includes registers for century, year, month, date, day, hours, minutes, and seconds in 24-hour BCD format. The clock registers are double-buffered to ensure accurate data during updates, preventing time loss. It has built-in power fail circuitry that disconnects the device when the supply voltage falls outside specified limits. The device operates within a voltage range of 4.5V to 5.5V, with an operating temperature range from 0°C to 70°C. It integrates NV SRAM, real-time clock, crystal, power fail control, and a lithium energy source, providing over 10 years of non-volatile operation without power. Access time to clock registers is 70ns, and it features a battery voltage level indicator and power-fail write protection tolerating ±10% supply variation. The lithium backup battery is electrically disconnected to maintain freshness. It is UL recognized and suitable for clock and timing applications.
