ISSI IS62WVS2568GBLL-45NLI

The ISSI IS62/65WVS2568GALL/GBLL are 2M bit Fast Serial static RAMs organized as 256K bytes by 8 bits. It is fabricated using ISSI's high-performance CMOS technology. The device 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 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. The IS62/65WVS5128GALL/GBLL are available in the standard 8-pin SOIC package.
