30-Ball Part Pinout
Table 4. CY8C20766A, CY8C20746A 30-Ball Part Pinout (WLCSP)
1. On power up , the SDA(P1[0]) drives a strong high for 256 sleep clock cycles and drives resistive low for the next 256 sleep clock cycles. The SCL(P1[1])line drives
2. Alternate SPI clock.

resistive low for 512 sleep clock cycles and both the pins transition to high impedance state. On reset, after XRES de-asserts, the SDA and the SCL lines drive
resistive low for 8 sleep clock cycles and transition to high impedance state. Hence, during power up or reset event, P1[1] and P1[0] may disturb the I2C bus. Use
alternate pins if you encounter issues.
