i've been following the updates to USB3 (10 gigabit speeds now with<br>
USB 3.1). in combination with:<br>
<br>
* the development of both the tablet and the laptop not having room<br>
for an ethernet port<br>
* the development of lower-cost SoCs not really having ethernet<br>
* the fact that the ethernet components cost around $2 when the SoCs<br>
themselves are around $2 to $4<br>
<br>
... i'm coming to the conclusion that Ethernet should be removed, and<br>
the 9 lines used to<br>
<br>
* increase the USB3.0 allocation (4 wires) to USB 3.1 (8 wires)<br>
* this would leave 5 spare pins for GPIO.<br>
* at least two of those should be EINT-capable GPIOs<br>
<br>
this would make it possible to redesign the tablet PCB to a more<br>
"standard" one - removing the need for the I2C GPIO chip for example.<br>
<br>
if there are any products that need ethernet, it can be done as a USB2<br>
or USB3 compliant external IC.<br>
<br>
the IC3128 PCB can be reduced down to around a $12 BOM, the EOMA68-A20<br>
PCB can be reduced by a further $2.50.<br>
<br>
any thoughts or objections, much appreciated the input.<br>
