Actually it was 20uA and it was the average power assuming which covers sleep, wake, send, listen. I might be off by a few uA, but it should be close.
Cypress ships several BT SoCs with different capabilities and different price tag. You should be able to find info WICED Studio Bluetooth. Which one you need for your project will depend on what functionality you want to enable in addition to sleep. If you do not need much more other than sleep and wake the host when a valid packet is received, you can probably use any chip.
