Hello,
我have some questions since I am not able to find the right parameter in the DS/docs:
- What is the max output load current provided by a GPIO ? I am going to power a digital microphone using a GPIO pin in output mode, much like in the Wearable reference.
The digital mic in my case needs 600uA in Normal mode of operation.
- Need to store persistent data in the built-in flash memory (via QSPI controller) of DA14680. DS specifies that data can be written by specifying the sector number, etc.
But how the built-in flash memory is organized ? Eg. I need to know number of sectors/pages, bytes per sector, etc and any useful info how to deal with writing to it correctly.
Thank you,

嗨tektronic,
- You will be able to find the Drive current of the GPIO's in the datasheet for every pin in Table 2: Pin description which is 4.8(mA).
- The 68x SDK provides partitions in order for the user to store data in the internal flash (please check the document UM-B-044-DA1468x Software Platform Reference.pdf), regarding the flash that the 680 is equipped, the flash is organized in 4.096 programmable pages of 256 - bytes each and sectors divided into 4KB.Pages can be erased in groups of 16 (4KB sector erase), groups of 128 (32KB block erase), groups of 256 (64KB block erase) or the entire chip.
Thanks MT_dialog
Hello,
Table 2 is the most important in DS.... How did i miss that column ? :) ...
Thank you for flash info also.
