SPMOD_PSRAM(PSRAM module) uses IPS6404L-SQ PSRAM.

    SPMOD - PSRAM Introduction

    • Using Sipeed-SPMOD interface(2.54mm * 8PIN ),unified MaixPy board interface
    • Connect to the board through the SP-MOD SPI/QPI interface
    • Pseudo−SRAM:IPS6404L-SQ is 64 Mbit of SPI/QPI (serial/quad parallel interface) Pseudo−SRAM device.
    • Working frequency:104MHz
    • CLK period:30.3ns
    • Size:15.0*10.0*13.3mm
