EKM6251 datasheet

Description :

The EKM6251 is standard RF Mouse Receiver (Rx) Controller for USB and PS/2 compatible

It’sreceives the RF packet data fromRF 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’shave built-in RF signal sampling and noise immunity function to improve the RF data decode efficiency.

Features : 

1. Operating voltage: 2.5V~5.5V

2. Built-in regulator to generate 3.3V

3. Operating frequency: 6.00Mhz

4.  Built-in USB Device Controller and Interface.

5. Support USB and PS/2 detect mode and compatible interface.

6. Built-in EEPROM to storage 1 byte Device ID (255 sets)


7. Built-in RF signal sampling and noise immunity function.

Applications : 

1. USB RF Mouse Rx

2. PS/2 RF Mouse Rx
