The SPI bus is used to control the AmP device and program both AmP and flash memory. The I2C bus provides control and monitoring of the power supply functions of the AmP device. GPIO is used for evaluation board configuration and to support functions on the SPI interface. All pins use 3.3V logic except where otherwise stated.

This enables the application to have a smaller footprint with fewer connections. Three Standard Interface pinouts are recommended and supported as defined follows: Standard Interface Total Pins AmPLink12 12 AmPLink12 Basic 6 AmPLink12 Basic Edge 6 SPI yes yes yes I2C yes no no pin pitch 0.1 inch 0.1 inch 0.1 inch cable length 4 inches 4 inches 4 inches AmPLink Pinouts AmPLink Images Copyright © 2020, AnDAPT, Inc. 3 02/01/2020 AmPLink USB Adapter AmPLink Electrical Characteristics Description VBUS (5V) output maximum current 3.3V output maximum current Inputs and outputs GPIO pin maximum output current Adapter supply current Condition current limit with foldback current limiting current limit with constant current limiting logic levels Assuming negligible current drawn from the IO connector Min 500 Typ Max 700 500 3.3 80 8 100 Unit mA mA V mA mA Precautions for Use The AmPLink USB Adapter features ESD protection, however, damage may occur at high ESD levels. Therefore, it is recommended that static handling precautions be followed at all times. Software AmPLink software is only intended for use with AnDAPT products. It can be downloaded from https://www.andapt.com/ WebAmP AmPLink download. Windows Driver Installation The AmPLink Adapter drivers will normally be installed automatically when an Adapter is plugged into a USB port on a PC. If this does not happen use the driver setup executable available from the FTDI website at http://www.ftdichip.com/Drivers/D2XX.htm. Choose the latest version based on your operating system. Windows AmPLink Control Installation The control software is available at https://www.andapt.com/ WebAmP tools download page. Download the zip file to your PC and unzip the AmPLink.zip folder onto your hard disk. Click on the executable to run the Windows control interface.
