The Evolution of SPI Flash Memory

The Changing Serial Flash Memory Landscape SPANSION Spansion FL-Ss SPI [pronounced "S.P.I" or "spy] The serial peripheral interface (SPI) is an interface that enables the serial (one bit at a time) exchange of data between two devices. It has been employed in systems for communication between processors and Flash memory. The simple serial interface requires fewer connections and thus fewer pins. This lowers cost, simplifies board layout and reduces the form factor of many embedded designs. SPANSION® FL-S SPI FLASH MEMORY ADVANCEMENTS 5X FASTER ERASE → Enables faster code update → Reduces chip 0.7 The year the serial peripheral interface 1979 was first used. re-programming time during manufacturing → Introduction of the board game Trivial Pursuit → Margaret Thatcher was Prime Minister of the United Kingdom → Superman The Movie was a big hit → M*A*S*H, The Love Boat, Taxi and Charlie's Angels were on TV 0.13 Spansion FL-S Micron N25Q Time to program 256 Mb → "My Sharona" by The Knack was #1 for 6 weeks on Billboard Charts 3X FASTER PROGRAM → Reduces programming 66 costs SERIAL VS.
