FEATURES
§ Measures four channels of data:
- Integrated 8-bit temperature sensor
- Integrated 8-bit analog-to-digital
converter (ADC) with a three-input mux
§ Digital thermometer measures temperature
-40 °C to +85°C in +0.5°C increments with
±2°C accuracy
§ Real-time clock/calendar (RTC) in BCD
format counts seconds, minutes, hours, date,
month, day of the week, and year with leap-
year compensation; fully Y2K-compliant
§ Automatically wakes up and measures
temperature and/or ADC data at user-
programmable 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 1
§ 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:
- 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 asynchronous
communications mode
§ Unique, factory lasered 64-bit serial number
