PRELIMINARY
CYW54907
Note: Either or both of the SPI interfaces can be used as CSC master interfaces. This is in addition to the two dedicated CSC
interfaces.
■ One SPI master interface for serial flash.
■ Six dedicated PWM outputs.
■ Two I2S interfaces.
■ 17 GPIOs.
■ IEEE 802.11 a/b/g/n/ac 1×1 2.4 GHz and 5 GHz radio.
■ Single- and dual-antenna support.
