Function
Chip select
A low on CS selects the chip. Always return CS high temporarily before
executing instructions.
Clock input
The data on DI is latched by a rising edge of CLK . Data is output to DO by a falling
edge of CLK . CLK is effective when CS is low.
Serial data input
This pin is used to enter addresses, commands, and data into the chip.
Serial data output
This pin outputs data from the chip.
Reset input
A low on this input resets the chip.
No connection (not connected internally)
1.8 V~5.5 V (for reading)
2.3~5.5 V (for writing)
0 V (GND)
