1 NCS Not-Chip-Select (active-low) Communication is enabled when NCS is low
1)
2 CLK Serial Clock External clock for serial communication
1)
3 SDI Serial Data In Serial data input (e.g. from a controller)
1)
4 SDO Serial Data Out Tri-state serial data output
1)
5 VDD Supply voltage – 6 SENTOUT SENT output Digital Output of the SENT Interface 7 NTCIN NTC Input Input pin for an external NTC 8 GND Ground – 1 SPI pins (Pin No. 1 - Pin No. 4) are used only during calibration and test. It is recommended to leave these pins floating in the application.
