SPI flash command sets are fun and worth learning about — after all, they could be the key to hacking your “smart” kettle. Need a 1.8 V level shifter while flashing?

Long-term, Infineon is working with memory-chip suppliers, memory-controller IP vendors, and other industry players to expand the ecosystem around Semper X1 and future flash chips with LPDDR.

SPI NOR flash runs at 1.8 V, but today’s advanced SoCs on sub-10-nm nodes operate at 1.2 V, hence the need for a 1.2-V I/O interface.
