SLG4KPDSC-DMO

The SLG4KPDSC-DMO is a keypad scanner demonstration board.

Using a microcontroller (MCU) or system-on-chip (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™ programmable mixed-signal matrix IC 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.
