WICED Studio Wi-Fi Combo

Hi,


We have a plan to use Azuewave module CU289 that has CYW43438 and STM32F412 to design Wi-Fi and BLE application.

This STM32F412 has internal Flash(512KB~1MB) and SRAM(256KB) and we'd like to know how much memory can the customer use for their application without some library and OS.

Thank you.

Hello,

The memory map for flash and RAM can be seen in WICED when any application is build.

I have attached the memory log for an application that does wiced_init() below:

This is the minimum requirement for initializing the device. RTOS and network stack is initialized as part of wiced_init().

Hi Priya

Thanks for your update.

This module has 1MB external flash memory on the module.

Does this IC combination expand ROM size of WICED application by adding external flash ?

Thank you.

The external flash does not expand the ROM.

The WICED application framework consists of multiple binaries. These binaries are copied into internal + external flash.

You can refer the Appnote for understanding the framework: ​<WICED>\43xxx_Wi-Fi\doc\WICED-Application-Framework.pdf
