16x2 I2C Character LCD
Part Number: CFA533-TMI-KC
I2C LCD With Keypad – White On Blue
The CFA533-***-KC series is a 16x2 I2C LCD with keypad. The I2C interface allows you to use just two lines (SDA & SCL) to have bi-directional communication with the I2C LCD. Other devices can also share those two I2C control lines with the LCD. Only 4 wires are needed to connect this I2C LCD: power, ground, SDA (I2C Serial DAta) and SCL (I2C Serial CLock).
The CFA533 can run on 3.3v to 5.0v directly, with no changes needed, so you do not need to do any level translation between your embedded processor and the I2C LCD. Simply power the CFA533 from the same supply as your processor and the I2C signal levels will match up.
Using only one address on your I2C bus, you can add all the elements that you need for your front panel. The CFA533 I2C LCD can also read up to 32 DS18B20 digital temperature sensors, giving you an easy way to integrate temperature sensing over the I2C bus. No additional firmware or pins are needed on the host system.
The CFA533-TMI display style has sharp white characters against a deep blue background. The keypad is backlit in a complementary blue. This I2C LCD is a backlit negative STN. The CFA533-TMI I2C LCD is viewable in any lighting condition from darkness to normal, bright office light. The CFA533-TMI negative STN is not recommended for use in full sunlight conditions. The CFA533 I2C LCD series is also available in dark-blue-on-white CFA533-TFH-KC and dark-on-yellow-green CFA533-YYH-KC color variants.
