Description
Signal Data Output: Transfers data serially out of the device on the falling edge of SCK.
Serial Data Input: Transfers data serially into the device. Device latches commands, addresses,
and program data on SI on the rising edge of SCK.
Serial Clock: Provides serial interface timing. Latches commands, addresses, and data on SI on
rising edge of SCK. Triggers output on SO after the falling edge of SCK.
Chip Select: Places device in active power mode when driven low. Deselects device and places
SO at high impedance when high. After power-up, device requires a falling edge on CS# before any
command is written. Device is in standby mode when a program, erase, or Write Status Register
operation is not in progress.
Hold: Pauses any serial communication with the device without deselecting it. When driven low,
SO is at high impedance, and all input at SI and SCK are ignored. Requires that CS# also be driven
low.
Write Protect: Protects the memory area specified by Status Register bits BP2:BP0. When driven
low, prevents any program or erase command from altering the data in the protected memory area.
