Detailed Description
The MAX7302 9-port, general-purpose port expander
operates from a 1.62V to 3.6V power supply. Port P1
can be configured as an input and an open-drain out-
put. Port P1 can also be configured to function as an
INT output. Ports P2–P9 can be configured as inputs,
push-pull outputs, and open-drain outputs. Ports P2–P9
can be used as simple configurable logic arrays
(CLAs) to form user-defined logic gates.
Each port configured as an open-drain or push-pull
output can sink up to 25mA. Push-pull outputs also
have a 5mA source drive capability. The MAX7302 is
rated to sink a total of 100mA into any combination of
its output ports. Output ports have PWM and blink
capabilities, as well as logic drive.
Initial Power-Up
On power-up, the MAX7302 default configuration has all
9 ports, P1–P9, configured as input ports with logic lev-
els referenced to V LA . 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, and PWM/blink
oscillator options, global blink period, and reset options
(see Tables 3 and 4).
