Datasheet

Connect Vcc to the power supply, 3V or 5V is fine. Use the same voltage that the

microcontroller logic is based off of. For most Arduinos, that is 5V

Connect GND to common power/data ground

Connect the SCL pin to the I2C clock SCL pin on your Arduino. On an UNO & '328

based Arduino, this is also known as A5, on a Mega it is also known as digital 21 and

on a Leonardo/Micro, digital 3

Connect the SDA pin to the I2C data SDA pin on your Arduino. On an UNO & '328

based Arduino, this is also known as A4, on a Mega it is also known as digital 20 and

on a Leonardo/Micro, digital 2

The I2C FRAM has a default I2C address of 0x50 but you can set the address to any of 8

values between 0x50 and 0x57 so you can have up to 8 of these chips all sharing the same

SCL/SDA pins. We suggest just connecting up the power and SDA/SCL pins for now. Once

you have things working, change up the address as desired.

Download Adafruit_FRAM_I2C

To begin reading and writing data to the chip, you will need to download Adafruit_FRAM_I2C

from our github repository (http://adafru.it/dtq). You can do that by visiting the github repo

and manually downloading or, easier, just click this button to download the zip
