The Microchip 23LC1024-I/SN is a 1 Mbit serial SRAM organized as 128K x 8 bits, accessed through an SPI bus that supports standard SPI, Dual I/O, and Quad I/O protocols. The Quad I/O mode effectively quadruples the read/write throughput compared to a single-bit SPI interface, making it a fit for applications that need fast temporary storage — data logging buffers, display frame buffers, or communication packet queues — without the endurance limits or slower write cycles of EEPROM or Flash. The volatile memory type means data is lost at power-off, so it is used for scratchpad or cache, not persistent storage. The 20 MHz clock rate delivers a peak transfer of 80 Mbps in Quad I/O mode, enough to keep up with many MCU SPI peripherals without wait states.
