eKK6111
RF KEYBOARD DECODER
Preliminary
GENERAL DESCRIPTION
In RF keyboard system, that is divided into two parts (the transmitter and the receiver). The eKK6111
micro-controller is dedicated to RF keyboard decoder for single channel RF Rx module. The eKK6111 is decode the
data from RF Rx module, control all scan codes, three LEDs status and communication with PC. That is specially
designed for IBM PC AT and all compatible machines.
