Pinout
1. CS# (Chip Select): This active-low pin enables communication between the host and the memory chip.
2. DO (Data Out): This pin outputs data from the chip to the host during read operations.
3. WP# (Write Protect): This active-low pin can be used to protect certain sections of the memory from being erased or programmed.
4. GND: Ground reference for the chip.
5. DI (Data In): This pin is used to input data into the chip or to receive commands from the host.
6. CLK (Clock): Provides the clock signal required for synchronizing data transfers.
7. HOLD#: This active-low pin pauses any serial communication, allowing the interface to be held in a suspended state.
8. VCC: Supplies the power to the chip, typically 2.7V to 3.6V.
These pins enable the W25X40CLSNIG to interface with a microcontroller through the SPI (Serial Peripheral Interface) protocol, allowing operations such as reading, writing, and erasing data.
