Pin Description:
| PIN | Functional description |
| IO0 ~ IO7 | Multiplexed input / output The bidirectional I/Os transfer address, data, and command information. When C(-)E(-) pin is high,the I/Os is High impedance. |
| CLE | Command Latch Enable When CLE is high, the command is latched into the command register through the IO port on the rising edge of the signal. |
| ALE | Address Latch Enable When ALE is high,the address is latched into the address register through the IO port on the rising edge of the signal. |
| C(-)E(-) | Chip Enable Enables or disables the chip. |
| R(-)E(-) | Read Enable Control the output of serial data. When the signal is low, the data is driven to the IO port. Data is valid after tREA time on the falling edge of R(-)E(-), and the internal column address counter is incremented automatically. |
| W(-)E(-) | Write Enable Control the input of serial data,command, address and data is latched on the W(-)E(-) Rising edge. |
| R/B(-) | Ready/Busy output Indicates the device operating state. When low, indicates that programming, erase, or random read operation is in progress, when high, indicates that no operation or operation is finished. It is recommended to connect a pull-up resistor (4.7K~10K) to the pin. |
