概要

The SLG4KPDSC-DMO is a keypad scanner demonstration board.

Using an MCU or SoC to scan a keypad is a less than ideal solution for human input. It often makes sense to offload keypad scanning to a dedicated IC to reduce the power and I/O burden on larger, less efficient, and more expensive devices. Using a GreenPAK™ as a keypad scanner provides a flexible, reliable solution that won't kill your power budget or your BOM cost. While GreenPAK with I2C can perform this function, using GreenPAK's Asynchronous State Machine (ASM) unlocks the full potential and enables up to 54 key scanning.
