DS1680 - Portable System Controller

General Description

The DS1680 incorporates many functions necessary for low-power portable products, providing an RTC, NV RAM controller, microprocessor monitor, power- fail warning, 10-bit ADC, and a touch-screen controller in one chip.

Key Features

  • Real-time clock (RTC).
  • Counts seconds, minutes, hours, date, month, day of the week, and year with leap-year compensation valid up to 2100.
  • Power control circuitry supports system power-on from day/time alarm Microprocessor monitor.
  • Halts microprocessor during power- fail.
  • Automatically restarts microprocessor after power failure.
  • Monitors pushbutton for external override.
  • Halts and resets an out of control microprocessor NV RAM control.
