23A1024-I/SN

The 23A1024-I/SN is a 1MB serial Static Random Access Memory (SRAM) 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 your application needs faster data rates. This device also supports unlimited reads and writes to the memory array.

• SPI-compatible bus interface
• Low-power CMOS technology
• Unlimited read and write cycles
• Zero write time
• Byte, page and sequential mode for reads and writes
• High reliability
