BYTE-SELECT ADDRESS: Selects between high and low byte when the device is in x8 mode. This
address is latched during a x8 program cycle. Not used in x16 mode (i.e., the A0 input buffer is
turned off when BYTE# is high).
ADDRESS INPUTS: Inputs for addresses during read and program operations. Addresses are
internally latched during a program cycle:
32-Mbit — A[21:1]
64-Mbit— A[22:1]
128-Mbit — A[23:1]
256-Mbit — A[24:1] A24 acts as a virtual CE for the two devices. A24 at V
and A24 at V
LOW-BYTE DATA BUS: Inputs data during buffer writes and programming, and inputs commands
during CUI writes. Outputs array, CFI, identifier, or status data in the appropriate read mode. Data
is internally latched during write operations.
