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 * This specification are subject to be changed without notice. 1 2003/12/3 Preliminary eKM6711 Optical RF Mouse Tx Controller PIN ASSIGNMENT U16 1 2 3 4 5 6 7 8 9 SCLK RFC SDIO RFD OSCI NC /RESET OSCO VDD VSS PD L Connect R Z1 M Z2 E 18 17 16 15 14 13 12 11 10 eKM6711 PIN DESCRIPTOR Pin No. Symbol I/O Function 1 RFC O Power control for RF Tx module, It’s high active. 2 RFD O data output for RF Tx module. 3 NC - NC I Input pin with Schmitt trigger.
