MAX7313AEG+ by Analog Devices

16-Port I/O Expander with LED Intensity Control, Interrupt, and Hot-Insertion Protection


The MAX7313 I²C-compatible serial interfaced peripheral provides microprocessors with 16 I/O ports. Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA and 5.5V, or a logic input with transition detection. A 17th port can be used for transition detection interrupt, or as a general-purpose output. The outputs are capable of driving LEDs, or providing logic outputs with external resistive pullup up to 5.5V. PWM current drive is integrated with 8 bits of control. Four 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. Each output then has 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. All LEDs can be individually set to be on or off during either blink phase, or to ignore the blink control. The blink period is controlled by a register. The MAX7313 supports hot insertion. All port pins, the active-low INT output, SDA, SCL, and the slave-address inputs AD0-2 remain high impedance in power-down (V+ = 0V) with up to 6V asserted upon them. The MAX7313 is controlled through the 2-wire I²C/SMBus serial interface, and can be configured to any one of 64 I²C addresses.
