DS1620 FUNCTIONAL BLOCK DIAGRAM Figure 1
The DS1620 measures temperature using a bandgap-based temperature sensor. The temperature reading
is provided in a 9–bit, two’s complement reading by issuing a READ TEMPERATURE command. The
data is transmitted serially through the 3–wire serial interface, LSB first. The DS1620 can measure
temperature over the range of -55
°C to +125°C in 0.5°C increments. For Fahrenheit usage, a lookup table
or conversion factor must be used.
Since data is transmitted over the 3–wire bus LSB first, temperature data can be written to/read from the
DS1620 as either a 9–bit word (taking RST low after the 9th (MSB) bit), or as two transfers of 8–bit
words, with the most significant 7 bits being ignored or set to 0, as illustrated in Table 3. After the MSB,
the DS1620 will output 0s.
Note that temperature is represented in the DS1620 in terms of a
°C LSB, yielding the 9–bit format
shown in Figure 2.
