Getting Started

To interface with this EEPROM, configure your microcontroller SPI peripheral for Mode 0 or Mode 3. Ensure the Write Protect and Hold pins are tied to VCC if not actively used to prevent accidental write inhibition or bus suspension. Hardware implementation is straightforward as the device requires only a standard SPI bus and a decoupling capacitor near the VCC pin.
