description: |
|
||
|
|
The Ocelot ethernet switch family contains chips that have an internal CPU
|
||
|
|
(VSC7513, VSC7514) and chips that don't (VSC7511, VSC7512). All switches have
|
||
|
|
the option to be controlled externally via external interfaces like SPI or
|
||
|
|
PCIe.
|
||
|
|
|
||
|
|
The switch family is a multi-port networking switch that supports many
|
||
|
|
interfaces. Additionally, the device can perform pin control, MDIO buses, and
|
||
|
|
external GPIO expanders.
