Rainbow Electronics DS1615 - Manual

1 of 24 122800
FEATURES
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 (Y2K compatible)
Automatically wakes up and measures
temperature at user-programmable intervals
from 1 to 255 minutes
Logs up to 2048 consecutive temperature
measurements in read-only nonvolatile
memory
Records long-term temperature histogram in
63 bins with 2.0 °C resolution
Programmable temperature-high and
temperature-low alarm 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 and tested 64-bit
serial number
