DS1616
Temperature and Three Input
MUX鈥檈d 8-bit Data Recorder
www.dalsemi.com
FEATURES
Measures four channels of data:
鈭?/div>
Integrated 8-bit temperature sensor,
鈭?/div>
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擄C to +85擄C in 0.5擄C increments (-40擄F to
+183.2擄F in 0.9擄F increments)
Digital thermometer provides
鹵2擄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擄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
