Figure 2. Conversion Time and Period
The serial data of the TMP121 and TMP123 consists of
12-bit plus sign temperature data followed by a
confirmation bit and two high impedance bits. Data is
transmitted in Binary Two’s Complement format. Figure 3
describes the output data of the TMP121 and TMP123.
Timing Diagrams
The TMP121 and TMP123 are SPI-compatible. Figure 4
and Figure 5 describe the various timing requirements,
with parameters defined in Table 3.
