EKM6251

Preliminary GENERAL DESCRIPTOR eKM6251 U+P RF Mouse Rx Controller 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. FEATURE Operating voltage: 2.5V~5.5V Built-in regulator to generate 3.3V Operating frequency: 6.00Mhz Built-in USB Device Controller and Interface. Support USB and PS/2 detect mode and compatible interface. Built-in EEPROM to storage 1 byte Device ID (255 sets) Built-in RF signal sampling and noise immunity function. Support a LED to display RF packet receive status and ID set mode. Using jump connect to set Device ID into default ID. Support RF monitor pin to check RF packet receive situation.
