The MAX6965 I²C-compatible serial interfaced peripheral provides microprocessors with nine additional output ports. Each output is an open-drain current-sinking output rated to 50mA at 7V. All outputs are capable of driving LEDs, or providing logic outputs with external resistive pullup up to 7V. Eight-bit PWM current control is also integrated. Four of the bits are global control and apply to all LED outputs to provide coarse adjustment of current from fully off to fully on with 14 intensity steps. Additionally each output then has an individual 4-bit control, which further divides the globally set current into 16 more steps. Alternatively, the current control can be configured as a single 8-bit control that sets all outputs at once. Each output has independent blink timing with two blink phases. LEDs can be individually set to be either on or off during either blink phase, or to ignore the blink control. The blink period is controlled by an external clock (up to 1kHz) on BLINK or by a register. The BLINK input can also be used as a logic control to turn the LEDs on and off, or as a general-purpose input (GPI). The MAX6965 supports hot insertion. The SDA, SCL, active-low RST, BLINK, and the slave address input AD0 remain high impedance in power-down (V+ = 0V) with up to 6V asserted upon them. The output ports remain high impedance with up to 8V asserted upon them. The MAX6965 is controlled through a 2-wire I²C serial interface, and can be configured to one of four I²C addresses.
