Other Parts Discussed in Thread: TMP112
Hello,
I have the followin questions about the schematics of AWR1843AOPEVM (PROC106B).
1) There is a temperature sensor IC (U5; TMP112) on the EVM board.
What temperature does this IC sense and in what cases does it generate an alert?
2) There is a EEPROM (U6; CAT24C08TDI) on the EVM board.
What is the use for this EEPROM? Please let me know an example.
3) There is PMIC(U1; LP87524JRNFRQ1) on the EVM board.
The PMIC has an external clock input pin (3pin). It is described "Connect to ground if external clock is not used." on the datasheet.
But the external clock input pin is not connected in GND in the schematics of AWR1843AOPEVM. (Please see the image)
Please let me know why the external clock input pin is not connected to GND.
Please advise,
Thanks and regards,
Shoko
