General Description
The MAX7313 I
2
C-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 global-
ly set current into 16 more steps. Alternatively, the cur-
rent control can be configured as a single 8-bit control
that sets all outputs at once.
The MAX7313 is pin and software compatible with the
MAX7311, PCA9535, and PCA9555.
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
INT
output, SDA, SCL, and the slave-address inputs
ADO-2 remain high impedance in power-down (V+ =0V)
with up to 6V asserted upon them.
The MAX7313 is controlled through the 2-wire
I
2
C/SMBus serial interface, and can be configured to
any one of 64 I
2
C addresses.
