Detailed Description
The MAX7306/MAX7307 4-port, general-purpose port
expanders operate from a 1.62V to 3.6V power supply.
Ports P2 through P4 can be configured as inputs, push-
pull outputs, and open-drain outputs. Port P1 can be
configured as an input and an open-drain output; P1
can also be configured to function as an ( INT ) output.
Each port configured as an open-drain or push-pull
output can sink up to 25mA. Push-pull outputs also
have a 10mA source drive capability. The MAX7306/
MAX7307 are rated to sink a total of 100mA into any
combination of the output ports. Output ports have
PWM and blink capabilities, as well as logic drive.
Initial Power-Up
On power-up, the MAX7307 default configuration has
all ports configured as input ports with logic levels ref-
erenced to V LA . The MAX7306 default configuration
has all ports configured as input ports with logic levels
referenced to V DD . The transition detection interrupt
status flag resets and stays high (see Tables 1 and 2).
Device Configuration Registers
The device configuration registers set up the interrupt
function, serial-interface bus timeout, PWM/blink, oscil-
lator options, global blink period, and reset options
(see Tables 3 and 4).
