Key Encoder IC can monitor up to 8x8 matrix (64 keys), which means to be adaptable to Qwerty keyboard.

We adopt the architecture that the information of the only key which status is changed, like push or release, is encoded into the 8 bits data.

This can greatly reduce the CPU load which tends to become heavier as the number of keys increase.
