Most versions of the KL SN102 layout utilize a standard parallel or synchronous serial configuration to communicate with host microcontrollers (such as legacy Sanyo, Koyo, or modern industrial PLCs). Below is the standard physical pin mapping found across common industrial variations: Ground connection (0V). VDD (Pin 2): +5V Power supply for logic circuits.
