National Instruments 781964-03 I2C and SPI Interface Device .
The part number 781964-03 from National Instruments is the identifying part number for the USB-8452 I2C and SPI Interface Device. This model features both master and slave modes for I2C communication with clock rates ranging from standard to high speed modes. The I2C Standard Mode ranges from 16 kHz to 100 kHz, I2C Fast Mode ranges from 125 kHz to 400 kHz, I2C Fast Mode Plus ranges from 500 kHz to 1 MHz and the I2C high speed mode ranges from 1.11 MHz to 3.33 MHz while for the slave mode, the supported clock rates are up to 3.4 MHz with an output driver type of Open Drain and absolute voltage range -0.5 V to +5.5 V with respect to GND requiring an absolute input current of 40 mA max.
For SPI communication, it offers a wide range of supported clock rates ranging from 25 kHz to 50 MHz and configurable parameters, including bit order and transfer size of 4 bits to 64 bits, software selectable. It has an output driver type of Push-pull (active drive) and Absolute voltage range -0.5 V to +5.5 V with respect to GND.
The 781964-03 model is made with 8 digital input output lines supporting various voltage levels and with an output driver type of Push-pull (active drive) or open-drain, software selectable. This model is deigned to operate at an ambient temperature of 0 to 45 degrees Celsius with an operating humidity of 10% to 90% RH, noncondensing. It has an storage temperature -40 to 85 degrees Celsius and storage humidity of 5% to 90% RH, noncondensing. It requires to be installed at an maximum altitude of 2,000 m (at 25 °C ambient temperature) and a pollution degree of 2.
This model is compact and lightweight with physical dimensions of 7.26 cm × 9.19 cm × 2.03 cm (2.86 in. × 3.62 in. × 0.8 in.) and weighs 79 grams and with Input and output connectors of 1 × right angle USB series B receptacle, 1 × right angle male IDE cable receptacle. The 781964-03requires a bus interface of USB 2.0 High-Speed (480 Mb/s) that requires an Input voltage of 4.5 V min, 5.25 V max with a working mode current 500 mA maximum, 250 mA typical.
