Product Details

The MAX7314 evaluation kit (EV kit) is a fully assembled and tested surface-mount, 16-output LED driver printed-circuit board (PCB). The circuit uses the MAX7314 IC, an 18-port GPIO with LED intensity control, interrupt, and hot-insertion protection. The EV kit includes four RGB LEDs and four white LEDs (WLEDs) that can be controlled simultaneously by the MAX7314. The EV kit demonstrates the MAX7314 IC’s 8-bit PWM LED intensity control, two-phase LED blinking, reset, interrupt output, and unique single-pin, one-of-four I²C or 2-wire address features.

The MAX7314 EV kit also demonstrates the BLINK feature and includes a configurable oscillator circuit. The EV kit can also be reconfigured for evaluating a relay.

The MAX7314 EV kit provides PCB pads for the MAX7314 2-wire serial interface signals. A Windows 2000/XP/Vista®-compatible software is provided to access the MAX7314 IC. The MAX7314 EV kit can also be directly interfaced to a user-provided 2-wire system.
