Pinout
The CAT25640VI-GT3 is a 64-Kb SPI Serial CMOS EEPROM, produced by ON Semiconductor. It typically comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here is a brief overview of its pin functions:
1. CS (Chip Select): Activates the device when low, allowing it to process commands.
2. SO (Serial Data Output): Outputs data from the EEPROM during a read operation.
3. WP (Write Protect): Disables write operations when tied to Vcc, offering hardware data protection.
4. VSS: Ground connection, 0V reference.
5. SI (Serial Data Input): Inputs data and instructions to the device.
6. SCK (Serial Clock): Synchronizes the communication between the microcontroller and the EEPROM.
7. HOLD: Pauses communication without resetting the serial sequence, allowing the microcontroller to perform other tasks.
8. VCC: Power supply input for the device.
This configuration allows the EEPROM to interface with microcontrollers using the SPI protocol, providing non-volatile memory storage that retains data even when power is removed.
