Pinouts

The FRAM chip is the little guy in the middle. On the bottom we have the power and interface

pins

Power Pins:

VCC - this is the power pin. Since the chip uses 3-5VDC you should pick whatever the

logic voltage you're using. For most Arduino's that's 5V.

GND - common ground for power and logic

I2C Logic pins:

WP - Write Protect pin. This is used to force write protection so you cannot write to

the FRAM. It has an internal pulldown. Bring to a high voltage (VCC) to turn on WP

SCL - I2C clock pin, connect to your microcontrollers I2C clock line.
