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 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 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 asynchronous communications
mode
Unique, factory lasered 64-bit serial number
