Notes:

1. Refer to the reference design package for exact pin mapping and signal connection.

2. WINCS02IC does not support GPIO functionality. All the pins are reserved.

3. Do not connect any external 1.5V supply.

4. This pin can be used either as an oscillator input pin or as PTA BT_ACTIVE. Both functionalities cannot be supported

simultaneously.

5. Current firmware does not support the RTCC oscillator function; it is recommended to have an option to mount the

RTCC oscillator in the design to upgrade with the future version of firmware releases.

6. For more details, refer to the WINCS02 Module External Antenna Calibration Guide (DS50003753).

7. Do not leave this pin unconnected. Follow the directions in the Pin Description column for future upgrades.
