... General System Overview The SPIO-4 board is controlled via the Atmel SAM3U micro-controller that is based on an ARM M3, 32-bit embedded core. It provides the interface to the computer via a USB interface. The DUT board interfaces to the SPIO-4 via J6, the GPSI-16/32 connector. The GPSI-16/32 interface provides control, data and power to the DUT board ...

... There are several LED indicators on the SPIO4 board. the ones described bleow are driven directly by separate power rails on the SPIO4 board but as those rails can only be controlled by the processor they not only indicate a particular rails is on, they also show a state of the SPIO4 firmware as discussed below. Led D# ...

... GPSI connector could be connected to VDDIO on the DUT board. The level shifters are uni-directional. If VDDIO is not provided, the level shifters enter a shutdown state with all input pins tri- stated. The state passed along to the processor in this case would be logic low.

... Dev_INT~/SDRDY_A~ In certain applications, if required, this pin serves as the DRDY~ signal from the DUT to the SPIO-4. In other cases, this pin may be a general interrupt pin from the device to the SPIO-4. On the SPIO-4 board this signal connects to an interrupt pin on the microcontroller. ...

... VDDIO Interface Supply always provided by the DUT board. Both the DUT board and the SPIO-4 board power their I/O drivers with this supply (except the I2C bus – which is always +3.3V). Only the SPI_A related signals on the GPSI-16 subset are affected by this I/O supply. Voltage Range: 1 ...

... Power Requirements The SPIO-4 Data Capture Board can be solely powered via the USB interface power but can also be powered by external power supply. The SPIO-4 Data Capture Board consumes up to 500 mA of current depending on the DUT load. ADC evaluation boards differ widely in their power consumption – please consult the manual that came with your evaluation board, and verify if an external supply is required for your DUT board ...
