Function Descriptor
There are two types of EKM6611 series : EKM6611A and EKM6611B. The Table 1.1 summarizes the features of each type in EKM6611 series.
No. EKM6611A EKM6611B Osc. Freq. 4.00Mhz 4.00Mhz Z axis type XY scan rate Buttons Mechanica Photo 10.0KHz 6.6KHz 5 3 2-diode z axis photo comment
6.1 Oscillator Frequency
The external oscillator frequency is 4.00MHz, it's have higher movement scan rate (up to 10KHz).
6.2 Device ID
When EKM6611 is power-on, it initial to default ID (0xFF), first. EKM6611 is using the connect button to generate a random ID. After the button is pushed and released, the controller will generate a new ID (from 0x01 to 0xFF) and transmit the new ID to the receiver consecutively at least 10sec. Each power on time, the Device ID will set to 0xFF automatically. Only when the conflict occurs, user is needs to set ID manually.
6.3 Z-axis Type
The wheel of 3D mouse, which we used to call it Z-axis, it's detected by mechanical device or photo-couples. EKM6611_A, and EKM6611_B is support the latter. The noise immunity of photo-couples is better than the mechanical device. However, the photo-couples is more expensive.
6.4 Operation Mode
The EKM6611 have three operation modes, that's Operating Mode, Standby Mode and Sleep Mode. While the mouse is moving, the controller is working under the Operating Mode, sending the data to RF module for transmitting. If the mouse stops over 0.5 seconds, the EKM6611 will enter the Standby mode to reduce the consumption of power. Once the movement is detected or buttons are pushed, the controller will return to Operating mode. After working under the Standby Mode for an interval, it will enter Sleep Mode automatically. In Sleep Mode, the controller saves at least 95% consumption of power in Operating Mode.
