Overview

The TCA984649-EVM is used to evaluate the performance of the TCA9846 and TCA9849. The evaluation module (EVM) does not come with a soldered unit. A sample can be ordered online at the bottom of the product page. The EVM allows for engineers to evaluate the TCA9846 and TCA9849 I2C signaling capabilities. The EVM has a USB2ANY male connecter to send I2C signals through the DUT. The USB2ANY microcontroller has to be acquired separately and does not come with this EVM. If a USB2ANY is used for the communication, then the cable has to be connected with the notch facing up. A test point for each pin is present with many ground points for ease of use. Other features like load capacitor footprints and pull up resistors are for simplifying evaluation and testing.

Features
  • External power supply with decoupling capacitors from V_External to ground (2x 1μF 0603).
  • VDD1 and VDD2 test points for a second power supply connection option with decoupling capacitors (2x 100nF 0603, 2x 100pF 0603).
  • VDD1 and VDD2 banana jack plug ins for a third power supply connection option with the same decoupling capacitors (2x 100nF 0603, 2x 100pF 0603).
  • Two GND banana jack plug ins.
  • Ten test points for the I/Os.
  • A RESET test point and two additional ones for the addresses.
  • Eight GND test points for probing.
  • USB2ANY male connector for I2C signaling source from a microcontroller.
