DS1616

www.DataSheet4U.com PRELIMINARY DS1616 Temperature and Three Input MUX’ed 8-bit Data Recorder www.dalsemi.com FEATURES Measures four channels of data: − Integrated 8-bit temperature sensor, − Integrated 8-bit Analog-to-Digital Converter (ADC) with a three input mux for measuring up to three external sensors 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) Digital thermometer provides ±2°C accuracy Real Time Clock/Calendar in BCD format counts seconds, minutes, hours, date, month, day of the week, and year with leap year compensation. The Real Time Clock is fully Y2K-compliant Automatically wakes up and measures temperature and/or ADC data at userprogrammable intervals from 1 to 255 minutes 2048-byte datalog memory Records long-term temperature histogram in 63 bins with 2.0°C resolution Records long-term ADC data histogram in 64 bins with 4-bit resolution/bin (32 mV/bin) for ADC Channel One Programmable temperature-high and -low alarm trip points Programmable ADC data-high and -low alarm trip points Records time stamp and duration when temperature or ADC Channel 1 Data leaves the interval specified by the trip points Two serial interface options: synchronous and asynchronous - 3-wire synchronous serial interface - Asynchronous serial interface compatible with standard UARTs Memory partitioned into 32 byte pages for packetizing data On-chip 16-bit CRC generator to safeguard data read operations in asynchronou...
