Product Overview

781964-02 is an USB-8452 3.3MHz I²C, 50MHz SPI I2C/SPI interface device. The NI USB‑8452 is a host interface for connecting to and communicating with inter-integrated circuit (I2C) and serial peripheral interface (SPI) devices. With plug‑and‑play USB connectivity, the USB‑8452 is a bus-powered, portable solution to communicate with consumer electronics and integrated circuits. It also includes eight general-purpose digital I/O lines for a variety of applications, such as configuring the address of I²C devices, toggling LEDs, or strobing convert and data ready lines common to analogue converter chips. User can physically place the USB‑8452 more closely than PCI interfaces to I2C/SPI devices, which reduces I²C bus length and minimizes noise problems. Additionally, the interface provides +5V and GND to power circuits with no external power supply.
