SPI Flash IC

I'm looking for a storage IC to use in a project. There used to be one that Adafruit sold, but I see that it's discontinued, and I can't find one anywhere online.

Is there a common, go-to SPI Flash chip that people use?

Thanks!

You mean like a non volatile memory chip?
Why not use an EEPROM ? Does it have to be SPI? Why not I2C?

You can use any EEPROM chip or flash you find/like. Note however, that the write cycles are not infinite.

Some kind of easy-to-use serial interface like twi or spi is beneficial as they do not consume as much output pins.

D'oh! You're absolutely right! Didn't think of EEPROM. Thank you!
