Pin Function
CE: CE is used to select the device. The status returns to the standby at the rising edge of CE in the reading
operation. However, the status does not return to the standby at the rising edge of CE in the busy state in
programming and erase operation.
OE: Memory data and status register data can be read, when OE is V
WE: Commands and address are latched at the rising edge of WE.
SC: Programming and reading data is latched at the rising edge of SC.
RES: RES pin must be kept at the V
in the memory is protected against unintentional erase and programming. RES must be kept at the V
± 0.2 V) level during any operations such as programming, erase and read.
CDE: Commands and data are latched when CDE is V
RDY/Busy: The RDY/Busy indicates the program/erase status of the flash memory. The RDY/Busy signal
is initially at a high impedance state. It turns to a V
operation or the (B0H) command in erase operation. After the erase or programming operation finishes, the
RDY/Busy signal turns back to the high impedance state.
I/O0 to I/O7: The I/O pins are used to input data, address and command, and are used to output memory data
and status register data.
