WebJun 27, 2016 · \$\begingroup\$ bare SPI flash chips can be much smaller and cheaper than SD cards, I've seen some 2Mbyte BGA parts for $2 or so and they're 1.8x2.5mm, grain-of-rice size \$\endgroup\$ ... Flash is great for big data that doesn't change often. It is available cheaply for big sizes, but when you need to overwrite data, you can do it only for a ... WebDec 13, 2012 · All commands and data are issued to the SPI flash using the SPI bus. The sequence to read a SPI Flash is: 1) Start with CS_ high. 2) Bring CS_ low. 3) Issue "Read" op code to SPI Flash. 4) Issue three address bytes to SPI Flash. 5) "Receive" four garbage words in Receive Buffer. 6) Transmit as many arbitrary bytes (don't cares) as you wish to ...
