Big data NAND flash with no limits for MCUs

Using large NAND flash memory with the most basic of microcontrollers has got a little easier with a block grouping feature for Segger’s emFile file system, which reduces RAM requirements for block management.

NAND flash is typically used to store large data in embedded systems. However, when using external…
