Wi-Fi Combo

Greetings everyone,

Kindly provide me the information whether this chip CYW4343W WiFi + BT Combo Chip has in-built Bluetooth and TCP/IP stacks running in it?

I require a Bluetooth WiFi combo chip for my product which has the host as STM32H7 microcontroller. The host is already loaded and it can't take the network stacks running on it. So I'm searching for a wireless combo chip which can communicate to the host with plug and play communication interfaces (like UART, SDIO etc.).

I'm using this PSoC® 6 WiFi-BT Pioneer Kit (CY8CKIT-062-WiFi-BT) eval kit which has CYW4343W WiFi + BT Combo Chip.

My question is can I use this CYW4343W WiFi + BT Combo Chip is

1. independently programmable?

2. portable with different microcontrollers (just by communicating through UART, SDIO etc.)?

3. whether it can be used as a standalone mcu+wireless module (or dedicated host is required for running network stacks)?

I'm also using a CYW943907AEVAL1F kit which has the chip BCM43907, which is a standalone device. Means it has WiFi module + ARM Cortex-R mcu which runs the network stack by itself. All I need is a UART interface from STM32H7 to communicate.

Whether the same can be achieved with CYW4343W, or it requires some additional load in the STM32H7?

Kindly share your knowledge about this chip.

Any help would be very much appreciated at this stage.

Hello:

    For 4343W,  I recommend PSOC as host controller since we have a lot of resources on it.

You can use other host controller also , but less supports compared with Psoc MCU in current release .

1. independently programmable?

2. portable with different microcontrollers (just by communicating through UART, SDIO etc.)?

3. whether it can be used as a standalone mcu+wireless module (or dedicated host is required for running network stacks)?

Currently, from what I know  4343W can't be used as standalone chip , but still you can get a confirmed answer from sales or marketing person.     dedicated host is required for running network stacks , this is right .

Hello,

Thank you very much for the clarification.

The environment is very power constrained so I can't afford a host (PSoC) and as well as 4343W. I'll look for a standalone chip like 43907 which has a Cortex-R4 + wireless in a single chip.

Thanks.
