Brand: Winbond Electronics Part Number: W25X20CLSNIG Memory Type: Serial Flash Memory Capacity: 2 Megabit (256KB) Interface: SPI (Serial Peripheral Interface) Package: SOP-8 or similar small-outline packagePin Function Specifications:
The exact pin configuration depends on the package type, which in the case of the W25X20CLSNIG is 8 pins (SOP-8). Here’s a breakdown of the pinout for the SOP-8 package:
Pin Number Pin Name Pin Function Description 1 CS# Chip Select. Active low signal to select the chip for communication. 2 SO Serial Output (Data Out). SPI data output pin from the memory. 3 WP# Write Protect. Active low signal to enable or disable write protection. 4 VSS Ground. Common ground reference for Power . 5 VCC Supply Voltage. Power pin, typically 2.7V to 3.6V. 6 SI Serial Input (Data In). SPI data input pin to the memory. 7 SCK Serial Clock . Clock pin for synchronizing SPI communication. 8 NC No Connection. Reserved pin, not connected to the internal circuit.Pinout Function Detail (for SOP-8):
This package has 8 pins, each with a specific function. Let's go deeper into each pin function:
CS# (Chip Select): This is a critical pin used in SPI communication. The device will only respond to commands when this pin is pulled low (active low). If not selected, the device ignores SPI signals. SO (Serial Output): This pin outputs data from the memory to the microcontroller or external device. It's used for data transmission when the memory is reading or transferring data. WP# (Write Protect): When low, it disables the write capability, ensuring the data cannot be modified. If left high, the memory can be written to normally. VSS (Ground): This pin must be connected to the ground of the system, providing a common reference for voltage levels in the chip. VCC (Supply Voltage): The pin that connects the power supply to the chip. The recommended operating voltage is typically between 2.7V and 3.6V. SI (Serial Input): The input pin for the data coming from the microcontroller or external device. SPI data is sent on this pin to write data into the memory. SCK (Serial Clock): The clock signal pin used to synchronize SPI data transmission. It determines the timing for data sampling on the SI and SO pins. NC (No Connection): This pin is not internally connected to the circuit and does not have any electrical function within the device.FAQs (20 Frequently Asked Questions):
