Frequently asked questions
How do I wire this EEPROM to a microcontroller?
Connect CS, SCK, SI (MOSI), SO (MISO), VCC and GND. WP and HOLD are normally held high when unused. Confirm pin functions and the WP/HOLD requirements in the datasheet before wiring.
Can I replace it with other 32 Kbit SPI EEPROMs?
Other 32 Kbit SPI EEPROMs in the same 25-series family use similar command sets, but check pinout, voltage range and clock speed in both datasheets before substituting.
