Specifications of MAX7314EVKIT+

Operating Supply Voltage
2 V to 3.6 V
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 I
The MAX7314 EV kit also demonstrates the BLINK fea-
ture 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
access the MAX7314 IC. The MAX7314 EV kit can also
be directly interfaced to a user-provided 2-wire system.
