TEMPERATURE REGISTERS (60h-61h)
The DS2436 can measure temperature without external components. The resulting temperature
measurement is placed in a 2-byte Temperature Register. This register is implemented in SRAM, and
therefore will hold data until the battery voltage falls below minimum V
DD
.
The temperature reading is provided in a 13-bit, two’s complement format, with 0.03125°C resolution.
Table 1 describes the exact relationship of output data to measured temperature. The data is transmitted
serially over the 1-Wire interface. The DS2436 can measure temperature over the range of -40°C to
+85°C in 0.03125°C increments. For Fahrenheit usage, a lookup table or conversion factor must be used.
Note that temperature is represented in the DS2436 in terms of a 0.03125°C LSB, yielding the following
13-bit format:
