eKM6211
RF Mouse Rx Controller
1 General Descriptor
The eKM6211 is standard RF Mouse Receiver (Rx) Controller for 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 PS/2 interface. The eKM6211
have two way to set device ID, it’s DIP switch select and EEPROM(93C46) to storage.
It’s have built-in RF signal sampling and noise immunity function to improve the RF
data decode efficiency.
2 Feature
Operating voltage: 2.5V~5.5V
Built-in regulator to generate 3.3V
Operating frequency: 4.00Mhz
Support PS/2 compatible interface.
Device ID:
www.DataSheet4U.com
DIP switch to select 8 sets ID
EEPROM interface to storage 255 sets Device ID
Support a LED to display RF packet receive status and ID set mode.
Using jump connect to set Device ID into default ID.
To match with RF Mouse Tx controller:
eKM6611 series : RF Mouse Tx
eKM6711 : Optical RF Mouse Tx
Package:
16 pin DIP and SOP (300mil)
3 Application
PS/2 RF Mouse Rx

6.1.5.2 Resend (FE)
A Any time eKM6211 receives an invalid command, it returns a Resend command to
the system.
B When eKM6211 receives a Resend command, it retransmits its last packet of data.
If the last packet was a Resend command, it transmits the packet just prior to the
Resend command.
C In stream mode, if a Resend command is received by eKM6211 immediately
following a 3-byte data packet transmission to the system.
6.1.5.3 Set Default (F6)
The command reinitializes all conditions to the power-on defaults.
6.1.5.4 Disable (F5)
This command is used in the stream mode to stop transmissions from eKM6211.
6.1.5.5 Enable (F4)
Begins transmissions, if in stream mode.
6.1.5.6 Set Sampling Rate (F3, XX)
In the stream mode, this command set the sampling rate to the value indicated by byte
hex XX, shown in following:
Second byte XX
Sample Rate
0A 10/sec
14 20/sec
28 40/sec
3c 60/sec
50 80/sec
64 100/sec
C9 200/sec
6.1.5.7 Read Device Type (F2)
eKM6211 always echoes " FA, 00" following this command.
6.1.5.8 Set Remote Mode (F0)
Data values are reported only in response to a Read Data command.
6.1.5.9 Set Wrap Mode (EE)
Wrap mode remains until Reset (FF) or Reset Wrap Mode (EC) is received.
6.1.5.10 Reset Wrap Mode (EC)
eKM6211 returns to the previous mode of operation after receiving this command.
