General Description
The MAX7316 I2C/SMBus-compatible serial interfaced
peripheral provides microprocessors with eight additional
I/O ports plus 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. Additionally each out-
put 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 supports hot insertion. All port pins, the
INT output, SDA, SCL, RST, BLINK, and the slave
address input ADO remain high impedance in power-
down (V+ = 0V) with up to 6V asserted upon them.
The MAX7316 is controlled through a 2-wire serial inter-
face, and can be set to one of four I2C addresses.
