1.3 Specification

The TCA984748-EVM is used for evaluating TCA9847 and TCA9848. The EVM has four 3-pin headers and two headers for VDD1 and VDD2 supplies that can be connected to an external source or to the board ground. Two headers for setting the addresses A0 and A1 pins high or low. An additional nineteen 3-lane 3-pin headers for the option to pull up the bus to VDD1 through a 1k, 4.7k, or 10k resistor using a jumper.

The EVM has test points on each I/O (for a total of eighteen), and two test points for both supplies and two test points for the two address pins. Eight ground test points allow for more connection flexibility on the board.
