3V、非易失控制器，帶有鋰電池監(jiān)測器

The DS1314 Nonvolatile Controller with Battery Monitor is a CMOS circuit which solves the application problem of converting CMOS RAM into nonvolatile memory. Incoming power is monitored for an out-of-tolerance condition. When such a condition is detected, chip enable is inhibited to accomplish write \n? Converts CMOS SRAM into nonvolatile memory\n? Unconditionally write-protects SRAM when VCC is out of tolerance\n? Automatically switches to battery backup supply when VCC power failure occurs\n? Monitors voltage of a lithium cell and provides advanced warning of impending battery failure\n? Sign;

隱含時鐘芯片

The DS1315 Phantom Time Chip is a combination of a CMOS timekeeper and a nonvolatile memory controller. In the absence of power, an external battery maintains the timekeeping operation and provides power for a CMOS static RAM. The watch keeps track of hundredths of seconds, seconds, minutes, hours, \n? Real-Time Clock Keeps Track of Hundredths of Seconds, Seconds, Minutes, Hours, Days, Date of the Month, Months, and Years\n? Automatic Leap Year Correction Valid Up to 2100\n? No Address Space Required to Communicate with RTC\n? Provides Nonvolatile Controller Functions for Battery Backup of SRA;
