Additional preview pages of the LM8322 datasheet.

The LM8322 Mobile I/O Companion is a dedicated device to unburden a host processor from scanning a matrix-addressed keypad.

Key Features.
Supports keypad matrices of up to 8 × 12 keys plus 8 special-function (SF) keys for a total of 104 keys. SF keys pull keypad scan inputs directly to ground, rather than connecting to a keypad scan output.
Supports I2C-compatible ACCESS. bus interface in slave mode up to 400 kHz (Fast-mode). 3.0.
