Low cost TCP enabled devices

Started by rowebits August 16, 2007
I noted that others were looking at and commenting on low cost solutions
for TCP and related services as network controllers.

One of the best solutions today is the Microchip dsPIC and PIC 24.  They
are not 8 bits but 16 bits and share lots of great pic features.  This is
what you get:

- low cost hardware
- support for just about all interconnect you can imagine (no firewire
though)
- cots software
- low cost development 
- off the shelf rtos products 
- tiny footprints
- dsp libraries
- complete integration

These are great devices, but the lack of iternal Ethernet makes them less suitable as TCP or network controllers. I've heard they're work on this, though, and may have an Ethernet member of the family next year. For now you'd need a separate Ethernet chip to use this family in that role. Eric

Pairing a PIC24F and an ENC27J60 is pretty painless, though.

IMHO the best features/cost solution for Ethernet embedded support are Luminary Stellaris family (LM3S6xxx). Fast, flash-based, ARM compatible, MAC+PHY *on chip*, all the libraries are free, and the prices start from 10$ for sampling quantities. -- emboliaschizoide.splinder.com

So do the rabbit and realtek;-) ali

I would guess the new T2 from Sun is probably overkill? :-)

Do they provide source as well? ali

Are the Luminary devices with built in Ethernet actually available yet? It seemed a little unclear from their website last time I looked (a few weeks ago). Martin

The Freescale MCF52230CAF60 costs $8,50&#4294967295; and has on-chip FLASH, SRAM, and Ethernet PHY. I'm using gcc for cross development under Linux.

The best solution I've seen so far is the PIC18F97J60 - 128KB Flash device 40Mhz clock, integrated Ethernet MAC+PHY and under $6 for 1K quantity. Microchip TCP-IP stack is the most sophisticated stack available royality free and with completely open source code. DHCP, FTP, SNMP, SMTP, HTTP, UDP, TCP, IP, PPP, SLIP, dynamic CGI scripts, Java scripts, once you fit the stack components inside your device you can do only web programming and no need to bother with the low level layers, all device resources are avaialble to you as dynamic %xx variables, so you can manipulate them. we have several boards based on the Microchip's stack (on the link in my signature), and I've never seen easier way to Internet enable something like with the free Microchip TCP-IP stack! you can program when push the button on your embedded devices to send e-mail with the measured ADC value, etc etc with two rows of web page html code - no need to dig in C nor assembly!
