They feature a 16-byte page write buffer and support the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS ¯¯ ) input. In addition, the required bus signals are a clock input (SCK), data input (SI) and data output (SO) lines. The HOLD ¯¯¯¯¯ input may be used to pause any serial communication with the CAT25010/20/40 device. These devices feature software and hardware write protection, including partial as well as full array protection. FUNCTIONAL SYMBOL For Ordering Information details, see page 16.
