Detailed Pin Configuration

The N25Q128A23B1240E has a total of 8 pins: 1. Chip Select (/CS): Enables communication with the chip when pulled low. 2. Serial Clock (SCLK): Provides the clock signal for data transfer. 3. Serial Data Input (SI): Receives data from the host device. 4. Serial Data Output (SO): Transmits data to the host device. 5. Hold (/HOLD): Pauses ongoing operations when pulled low. 6. Write Protect (/WP): Protects the memory from accidental writes when pulled high. 7. Ground (GND): Connects to the ground reference. 8. Power Supply (VCC): Provides the required power to the chip.

Functional Features

• High-speed data transfer: The SPI interface allows for fast read and write operations.
• Reliable data retention: The non-volatile nature of flash memory ensures data integrity even without power.
• Low power consumption: The chip operates efficiently, minimizing power usage.
• Sector-based erasure: Allows for selective erasure of specific memory sectors.
• Flexible write protection: The /WP pin can be used to prevent accidental writes.

Advantages

• Large storage capacity: The 128 Megabit capacity is suitable for various applications.
