General Description
The DS4520 is a 9-bit nonvolatile (NV) I/O expander with
64 bytes of NV user memory controlled by an I2C-
compatible serial interface. The DS4520 offers users a
digitally programmable alternative to hardware jumpers
and mechanical switches that are being used to control
digital logic nodes. Furthermore, the digital state of each
pin can be read through the serial interface. Each I/O
pin is independently configurable. The outputs are open
drain with selectable pullups. Each output has the ability
to sink up to 12mA. Since the device is NV, it powers up
in the desired state allowing it to control digital logic
inputs immediately on power-up without having to wait
for the host CPU to initiate control.
