Instructions for Use:
- Power Supply: Ensure the supply voltage is within the specified range of 1.7V to 5.5V.
- Pin Configuration: Refer to the datasheet for pin configuration and connect VCC and GND appropriately.
- SPI Communication: Initialize SPI communication using the correct clock speed (up to 20MHz). Ensure proper settings for master/slave mode, clock polarity, and phase.
- Write Operations: Before writing data, check if the Write Enable Latch (WEL) is set. Use the Write Enable (WREN) command to set it. After writing, use the Write Disable (WRDI) command.
- Read Operations: Initiate read commands by selecting the device with the Chip Select (CS) pin and sending the read address followed by reading the data bytes.
- Addressing: Use the appropriate addressing scheme based on the memory organization (16K x 8 bit).
- Endurance and Retention: Be mindful of the write cycle endurance limit (1,000,000 cycles) and data retention period (200 years).
- Temperature Considerations: Operate within the temperature range of -40°C to +85°C to ensure reliable performance.
For detailed specifications and further instructions, refer to the official CAT25128VI-GT3 datasheet provided by ON Semiconductor.
