23LCV512-I/ST

The 23LCV512-I/ST is a 512kB 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) is supported if your application needs faster data rates. This device also supports unlimited reads and writes to the memory array and supports data backup via external battery/coin cell connected to VBAT.

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