MAXIM MAX7316 Manual
Update: 30 September, 2023
The MAX7316 is an I2C/SMBus™-compatible serial interfaced peripheral from Texas Instruments. It provides microprocessors with eight additional I/O ports, as well as one output-only port and one input-only port. Each I/O port can be individually configured as either an open-drain current-sinking output rated to 50mA at 5.5V or as a logic input with transition detection. The output-only port can also be assigned as an interrupt out- put for transition detection. The outputs are capable of driving LEDs, or can provide logic outputs with external resistive pullup up to 5.5V. Eight-bit PWM current control is available for all nine out- put ports. Four bits are global control and apply to all LED outputs to provide coarse adjustment of current from fully off to fully on in 14 intensity steps. Additionaly 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. LEDs can be individually set to be on or off dur- ing either blink phase or to ignore the blink control. The blink period is controlled by an external clock input (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. The MAX7316 is controlled through a 2-wire serial inter- face, and can be set t
