TCA8424: The first HID over I2C keyboard controller
The TCA8424 is the first fixed logic keyboard scanner that is fully compatible with the new HID over I2C specification from Microsoft. In 2012, Microsoft introduced the HID over I2C specification, to interface HID class of devices over I2C. The system benefit is due to a simpler protocol that can operate at a lower operating voltage and consume less power. The TCA8424 has smaller package options, lower power consumption and no firmware development and can be more cost effective than other solutions.
