- Capacity: 128M-bit (16M-byte)
- Interface: SPI (Serial Peripheral Interface), which is a simple, efficient serial communication protocol for memory devices.
- Operating Voltage: Typically 2.7V to 3.6V
- Speed: Can support high-speed SPI (up to 104 MHz)
- Modes: Supports various modes of SPI such as Single, Dual, and Quad SPI.
Pin Functions:- ~CS (Pin 1): Chip Select input. This pin selects the chip for SPI communication.
- D1 (Pin 2): Data Input/Output (dual and quad mode).
- WP (Pin 3): Write Protect pin. This pin can be used to protect sectors of the memory.
- GND (Pin 4): Ground.
- D0 (Pin 5): Serial Data (MISO) or Data Input/Output (dual and quad mode).
- CLK (Pin 6): Serial Clock. This pin clocks the SPI data.
- HOLD (Pin 7): Hold input. Pauses operation.
- VCC (Pin 8): Power Supply.
- EP (Pin 9): Exposed pad (often connected to ground for heat dissipation).
Primary Functions:- Data Storage: It stores data non-volatilely, which means the data remains even when power is removed.
- Data Transfer: Facilitates high-speed data transfer via SPI. It can also operate in dual or quad modes for even faster data rates.
- Sector Erase/Write: Allows erasing and writing data in sectors or pages.
- Security Features: Write protection and other security features to prevent unintended writes or erases.
