PIN CONFIGURATIONS
DESCRIPTION
The DS1631, DS1631A, and DS1731 digital thermometers provide 9, 10, 11, or 12-bit temperature
readings over a -55°C to +125°C range. The DS1631 and DS1631A thermometer accuracy is 0.5°C
from 0°C to +70°C with 3.0V V
DD
5.5V, and the DS1731 accuracy is 1°C from -10°C to +85°C with
3.0V V
DD
5.5V. The thermostat on all three devices provides custom hysteresis with user-defined trip
points (T
H
and T
L
). The T
H
and T
L
registers and thermometer configuration settings are stored in NV
EEPROM so they can be programmed prior to installation. In addition, the DS1631A automatically
begins taking temperature measurements at power-up, which allows it to function as a stand-alone
thermostat. Communication with the DS1631/DS1631A/DS1731 is achieved through a 2-wire serial
interface, and three address pins allow up to eight devices to be multidropped on the same 2-wire bus.
Pin descriptions for the DS1631/DS1631A/DS1731 are provided in Table 2 and user-accessible registers
are summarized in Table 3. A functional diagram is shown in Figure 1.
