DALLAS SEMICONDUCTOR OFFERS THE INDUSTRY'S LOWEST COST, SINGLE-SUPPLY, BINARY TIMEKEEPER FOR ULTRA-LOW-POWER APPLICATIONS
DALLAS, TX—October 29, 2002—Dallas Semiconductor (NASDAQ: MXIM) introduces the DS1371 2-wire, 32-bit binary counter watchdog clock. The DS1371 combines a 32-bit binary counter, watchdog, periodic alarm, and programmable square-wave output in a small 8-pin µSOP package. Its small size and low-voltage operation make the DS1371 ideal for portable and battery-powered systems.
The 32-bit counter increments once per second, from which a software algorithm computes time of day, date, month, and year. An additional 24-bit counter can generate a periodic alarm or serve as a watchdog timer. If enabled as a watchdog timer, the watchdog strobe input pin provides a hardware reset of the counter. A configurable output can be used as an interrupt or provide a square wave at one of four selectable frequencies. Address and data are transferred serially through a 2-wire bus that operates from 1.7V to 5.5V. The oscillator keeps time while operating down to 1.3V, consuming less than 500nA (typ).
The DS1371 operates over the industrial temperature range (-40°C to +85°C) and is available in an 8-pin µSOP package. Prices start at $0.88 (1000-up, FOB USA).
