AND9106/D GU6701-E DSP Programmer Guide Description The DSP Programmer (GU6701−E) is a programming unit that http://onsemi.com interfaces between a computer and a hearing aid with ON Semiconductor DSP hybrid and can be used as a fast speed alternative to the Hi-Pro. Software in conjunction with the DSP APPLICATION NOTE Programmer makes up the whole programming unit. The DSP Programmer sends and receives data to/from the hearing aid to program the correct end-user configuration. The connection between the DSP Programmer and the PC The ON Semiconductor DSP Programmer is intended to is a USB specific cable supplied by ON Semiconductor. The be used in a production environment for high-speed connection between the DSP Programmer and the hearing communication with ON Semiconductor DSP hybrids and aid is a cable identical to the one used in HiPro applications. is intended for faster calibration and configuration of these These connections are located on the front panel with a pin products (see Figure 1). This unit does not have galvanic configuration as shown in Figure 3. The front panel also isolation. To program DSP hybrids, this system requires a provides power, as well as left and right communication DSP Programmer box, installation of an ARKt component LEDs. with a USB port available on the computer and the Software and drivers for the DSP Programmer are appropriate connecting cables (see Figure 2). included in the ARKbase distribution package. 80 70 Seconds 60 50 FRONTWAVE® 40 Calibration 30 Configuration 20 10 0 HiPro DSP Programmer Figure 1.

Hi−Pro/ON Semiconductor’s DSP Programmer Pin−out 4. To communicate with a hearing aid, ensure that the hearing aid cable is firmly inserted in the left or right port on the programmer. Sonion (http://www.sonion.com) and Knowles Electronics (http://www.knowles.com) offer several types of Hi-Pro compatible cables. Please refer to their catalogues for details. ON Semiconductor DSP Programmer adheres to the Hi-Pro socket configuration standard. Additional Notes for Windows XP 1. After running the executable and connecting the programmer, a series of dialog boxes will appear. In the Found New Hardware Wizard screen, ensure that the Install software automatically option is selected and then click Next. 2. If the Windows Logo Testing warning appears, click Continue Anyway. NOTE: The Found New Hardware Wizard may appear again, in which case repeat the above procedure. Software Installation The ARKbaset installation program installs the USB Controller Component DLL and the DSP Programmer drivers to the default locations on the computer and registers the Controller Component for immediate use with ARK-based applications. System Requirements The DSP Programmer is compatible with Windows versions 2000 and higher. The DSP Programmer requires ARKbase version 5.4.0 or higher. DSP Programmer Specification The ON Semiconductor DSP Programmer connects to the computer over full speed (12 Mbits) USB. The unit is capable of communicating with ON Semiconductor’s DSP hybrids at speeds up to 42 kbit/s (SDA) or 400 kbit/s (I2C). Communication with legacy analog parts is unsupported because the programmer is unable to provide a high voltage programming pulse. Two connections are provided for connection to hearing aids: left and right 6-pin Mini DIN sockets (similar to Hi-Pro). The programmer is approximately 5 in (127 mm) long, 3.75 in (95.3 mm) wide, and 1.65 in (41.9 mm) tall. Installing GenUSB on a Windows System 1. Download ARKbase to a known location on the hard drive. The installation file, along with the release notes, is located at http://ark.onsemi.com/support_Downloads.php 2. Run the executable by double-clicking on the icon. Accept all default options. 3. After the installation has finished, connect the DSP Programmer to the computer’s USB port and wait for the system to set up the device. The power light will turn on when the device is ready for use. http://onsemi.com 2 AND9106/D Electrical Specifications Pin 1: Fixed Supply Table 1. PIN 1 DESCRIPTION Parameter Min Output Voltage @ 100 mA Typical Max 1.28 Units V Output Current (Total sum of left and right ports) 100 mA Pin 4: SDA Data / I2C Data Pin 2: Analog Ground This pin is the bidirectional data line in both SDA and I2C mode. This pin is low impedance Ground. Pin 3: I2C Clock This pin is the I2C clock line (SCK) in I2C mode. It is unused in SDA mode. Table 2. PIN 4 DESCRIPTION (SDA mode) Min Typical Max Unit Output Voltage Low: [Vol] @ 2.5 mA Parameter - - 0.14 V Output Voltage High: [Voh] @ 2.5 mA 1.0 - - V Input Threshold (Rising Edge) - 0.56 - mV Input Threshold (Falling Edge) - 0.37 - mV Sync. Pulldown Resistor - 3 - kW Communication Pulldown Resistor - 562 - kW Pin 5: Floating Pin 6: Reserved Do not connect to this pin. Cable Capacitance The maximum cable capacitance recommended for use with the ON Semiconductor DSP Programmer is 500 pF. This refers to capacitance from the communication pin to any other pin or to the shield. The limitation is that the hearing aid is not capable of a fast enough slew rate to run at high speed while driving a capacitance larger than 500 pF.
