Pinout

The M25P64-VME6G is a 64 Mbit (8 MB) serial Flash memory device that uses an SPI (Serial Peripheral Interface) for communication. It typically comes in an 8-pin package with the following pin functions:
1. CS# (Chip Select): This pin is used to select the device. It must be driven low to enable the device for communication.
2. SCK (Serial Clock): This pin provides the clock signal for the SPI interface. Data is driven on the falling edge and sampled on the rising edge.
3. SI (Serial Input)/MOSI (Master Out Slave In): This pin is used to input instructions, addresses, or data to the memory.
4. SO (Serial Output)/MISO (Master In Slave Out): This pin outputs data from the memory to the master device.
5. WP# (Write Protect): This pin is used to protect against inadvertent write operations. It must be driven low to prevent writes.
6. HOLD#: This pin is used to pause communications with the device without deselecting it.
7. VCC: This is the power supply pin for the device.
8. VSS: This is the ground pin.
These pins together facilitate various operations such as read, write, erase, and more within the device.
