The Great Search - SPI SRAM Chip #adafruit #TheGreatSearch @digikey
For our E-Ink display breakout boards, we add an SRAM chip onboard to help buffer the display. Unlike TFTs that have built-in video RAM, EPDs require writing the full memory at once—which can get into multi-KBs.
For many modern chips, up to 64KB of video RAM isn't a big deal, but for small, low-cost micros like Arduino, that's a lot! Since EPDs are slow anyway, we can use an external SRAM chip for fast write/read—an ideal solution.
