DS1821 Programmable Digital Thermostat And Thermometer

The DS1821 CAN function as a standalone thermostat with user-programmable trip-points or as 8-bit Temperature Sensor with a 1-Wire digital Interface The thermostat trip-points are stored in nonvolatile memory, so DS1821 units CAN be programmed prior to system insertion for true standalone operation. The DS1821 has an operating temperature range of 55C to +125C and is accurate to 1C over a range of 0C to +85C. Communication with the DS1821 is accomplished through the open-drain DQ pin; this pin also serves as the thermostat output.
