10-Port I/O Expander with LED Intensity

Control, Interrupt, and Hot-Insertion Protection

General Description

The MAX7316 I

C/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 I

C addresses.
