The LM8323 key-scan controller is a dedicated device to unburden a host from scanning a matrixaddressed keypad.

1.
2 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).
Three Host-programmable PWM Outputs Useful for Smooth LED Brightness Modulation.
Supports General-purpose I/O Expansion on Pins Not Otherwise U.
