23LC1024 Datasheet PDF

●The 23LC1024-I/SN is a 1MB serial SRAM Device. The memory is accessed via a simple serial peripheral interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input. Additionally, SDI (serial dual interface) and SQI (serial quad interface) is supported if application needs faster data rates. This device also supports unlimited reads and writes to the memory array.
