Hi, I need low power industrial grade( operating temp -40 to 105C) controller with two 10/100 FE Ethernet MAC. Kindly suggest appropriate parts.
Hi
If you need to use Kinetis there are a couple of possibilities:
- add extra SPI (or parallel) connected Ethernet controllers - eg. https://community.nxp.com/message/504096
- use a Micrel KSZ8863 PHY and use its tail-tagging mode to create two independent Ethernet interfaces from a single Ethernet controller in a Kinetis part https://community.nxp.com/message/445668?commentID=445668#comment-445668
Both of these modes, and multi-homed networking, are fully integrated into the uTasker Kinetis project in case you also need a proven and immediately operational software solution to go with the hardware.... (also with integrated low power support of Kinetis part during operation).

Hi Arun,
You can check the following page for dual Ethernet MAC support.
MCF5441X|32 Bit Microcontroller (MCU)|NXP or VF5xx MPUs with ARM Cortex-A5 Core|Vybrid|NXP
Or if you insist using Kinetis, you can choose ARM Cortex-M4|Kinetis K64 120 MHz 32-bit MCUs|NXP and use Flexbus module to connect DM9000 for adding one more Ethernet interface.

As Fang said, there are no Kinetis parts with 2 Ethernet ports. Do you really need 2 separate networks, or could you put an ethernet switch chip on your board to give you the ports you need?
Hi,
Sorry, for Kinetis and LPC family, there has no parts with 2 Ethernet MAC. And we have I.MX parts has two ethernets, but it is not low power nor industrial grade( operating temp -40 to 105C). Sorry.
