The devices are SO Serial Data Output organized in blocks of x8-bit memory and support the WP Write-Protect Serial Peripheral Interface (SPI) compatible serial bus VSS Ground architecture. Byte-level and page-level functions are supported. The bus signals required are a clock input SI Serial Data Input (SCK) plus separate data in (SI) and data out (SO) SCK Serial Clock Input lines. Access to the device is controlled through a Chip HOLD Hold Input Select (CS) input. VCC Supply Voltage 2009-2021 Microchip Technology Inc.
