Is BCM43438KUBG P10 (or P11) related to BCM43438 A0 (or A1)?

What is the difference between them?

Do I have to use different firmware for them?

BCM43438 A0 is a Broadcom module; whereas CYW43438 A1 is a Cypress module and supported in WICED Studio. You have to use different firmware for them; i.e, Firmware for A1 version of chip (available with WICED SDK) won't work with BCM43438 A0.
