The eKM6251 is standard RF Mouse Receiver (Rx) Controller for USB and PS/2 compatible interface. It’s receives the RF packet data from RF Rx module (circuits). And decode the RF packet data and transmitting the data to PC by USB or PS/2 interface. The eKM6251 have internal EEPROM to storage the Device ID, do not need the external storage device like 93C46. It’s have built-in RF signal sampling and noise immunity function to improve the RF data decode efficiency.
