ETC EKM6711

Preliminary
eKM6711
Optical RF Mouse Tx Controller
GENERAL DESCRIPTOR
The eKM6711 is a transmitter (Tx) controller of optical RF mouse. The eKM6711 is reading
movement data of X axis and Y axis from optical mouse sensor using the serial data interface. Then,
encode the mouse status and 3-D, 4 buttons data to RF data packets. It ‘s requires the external RF
Tx module to transmit the RF data packets. The eKM6711 is to match with RF Mouse Rx controller
for eKM6211 series (PS/2) or eKM6251 (USB+PS2).
FEATURE
Operating voltage range: 2.2V~5.5V
Available in temperature range: 0℃~70℃
Operating frequency: 4.00Mhz
Support the 3D, 4 buttons and mechanical scrolling of z axis.
Support the serial data interface of optical mouse sensor. (Agilent ADNS-2030, ADNS-2051)
Efficient encoding algorithm for RF data packets.
Device ID
Power-on is default ID.
Using the push button to random generate the 255 sets ID.
Support 3 Operation Mode to saving power.
Operating mode
Standby mode : after 2 sec
Sleep mode : after 7 sec.
To match with RF Mouse Rx controller
eKM6211: PS/2 only
eKM6251: USB and PS/2
Package type: 18 pins DIP and SOP(300mil)
APPLICATION
3D, 4 buttons optical RF mouse
