LAUNCHCC3220MODASF: Is 1MB internal flash enough or do I need external flash?

Part Number:LAUNCHCC3220MODASF

Hi,

I have a custom board which has the CC3220MODASF module mounted. This module has 1MB flash included so I did not add any further external flash.

Now I am wondering if this 1MB is enough for a "normal" application?

I know it hardly depends on my application. Here is briefly what I am doing:

• Headless wifi-provisioning over HTTP
• MQTT Client with security using certificates (AWS IoT)
• OTA software updates
• UART communication with another MCU on the board.
• Basic data storage such as serial numbers, application states etc, no images or so.

Thanks for your advice.

Best,

Henry
