Description

The DS1615S is designed as an integrated temperature recorder that combines a real time clock with temperature data logging and histogram capabilities for applications that require temperature profiling over a given period of time.

DS1615S has many features. (1)Its digital thermometer measures temperature -40°C to +85°C in 0.5°C increments (-40°F to +183.2°F in 0.9°F increments). (2)Digital thermometer provides ±2°C accuracy. (3)Real time clock/calendar in BCD format counts seconds, minutes, hours, date, month, day of the week, and year with leap year compensation (Y2K compatible). (4)Automatically wakes up and measures temperature at user-programmable intervals from 1 to 255 minutes. (5)Logs up to 2048 consecutive temperature measurements in read-only nonvolatile memory. (6)Records long-term temperature histogram in 63 bins with 2.0°C resolution. (7)Programmable temperature-high and temperature-low alarm trip points. (8)Memory partitioned into 32-byte pages for packetizing data. And so on.

Some absolute maximum ratings of DS1615S have been concluded as follow. (1)Its voltage on any pin relative to ground would be from -0.3V to +7.0V. (2)Its operating temperature range would be from -40°C to +85°C. (3)Its storage temperature range would be from -55°C to +125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some DC characteristics of DS1615S are concluded as follow. (1)Its input leakage would be min -1uA and max +1uA. (2)Its logic 1 output would be min 2.4V. (3)Its logic 0 output would be max 0.4V. (4)Its TX and IO pins output current at 2.0V would be min -2.2mA. (5)Its TX, IO, and INT pins output current at 0.8V would be min 4mA. (6)Its active supply current would be typ 2mA and max 10mA. (7)Its temperature conversion current would be max 600uA. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
