Other Parts Discussed in Thread: TMP121
Let me ask about the relation between CS control and conversion time.
Datasheet of TMP123 describes the followings,
At "COMMUNICATING WITH THE TMP121" of APPLICATIONS INFROMATION in page5
"The TMP121 and TMP123 continuously convert temperatures to digital data while CS is high. "
"CS must be high for a minimum of one conversion time (320ms max) to update the temperature data."
The chart of electrical characteristics in page3 indicates
"conversion period is 640ms max", "Period indicates time between conversion starts."
From these, I recognized that A/D conversion in TMP123 ends until 320 ms max, and output SO from TMP123 until 320 ms max.
We determined to set the period of CS signal as 640ms, and 320ms for the duration time.
However, we also confirmed that the last sentence of "COMMUNICATING WITH THE TMP121" describes "A new conversion begins every 0.5s."
This statement makes us confuse if the conversion time can not be operated by external CS control(signal).
Can we also understand that a new conversion begins every 0.5s in TMP123 in the condition that CS pulled up high?
