Low cost uC with built-in Ethernet MAC + PHY

Not built in, but R8C/24 (16bit, 48k flash, 52-LQFP, $3.60 qty100) plus a CP2200 (48-TQFP, $5.62 qty100) fits your other specs. The R8C is available in various flash/package combinations, if you want to fine-tune the cost/flash balance.

Alternately, the M16C/30P - 16bit, 96K flash, 100-LQFP, $3.78 qty100.

If you allow microchip peripherals, the ENC28J is $3.54 qty100.

To save even more money, you can build gcc et al for the r8c/m16c/m32c platform and not have to pay any license fees for development tools. The r8c/m16c/m32c platform has a number of other development tool packages available also, like NC30 and IAR, and the gcc tools are supported via the FSF's mailing lists and two commercial support companies. (just in case anyone was wondering ;)

Also, CP2201 is cheaper - $4.77 qty100 - if you don't mind leadless packages (28-QFN).

Hi, all.

What current low-cost (USD $5-$10 in 1K) options do I have for a flash microcontroller (8/16/32 bit) with a built-in 10-base-T ethernet MAC+PHY, and reasonable program memory (say 32K or 64K minimum)?? Other than Microchip.

There are also 32-bit Renesas H8/300 parts (3062B "value series") with 128K of flash that come it at about $4.00 in low quantities.

Try the ASIX AX11015 - that's quite a capable 8 bit (100Mips) CPU with the ethernet 10/100Mbps MAC+PHY, and 128-512K Flash.

Claims $4.99/10K, so likely to be at the cheaper end of your price.

BTW: did you intentionally not set a Followup-To?

Maybe some new Coldfire derivatives, I'm not sure as IO don't need Ethernet. Atmel AT91SAM7X128 IIRC not "with MAC+PHY".

Thanks, Jim. I've run into that one in an IP camera, but didn't know the source. It even has the core regulator on chip.

I've also found an HC12 with the peripherals. Thanks, guys.

Hmm... Make sure that the NE64 is available as long as your product will be produced.

And consider broadcast messages - they can create much load for small micros.

Try the Freescale MCF52234

Hi,

there is nothing that beats the LPC2364 in price / performance. The only catch right now, limited availability. No on-chip PHY but an ARM7 with 128k Flash 34k SRAM with Ethernet and USB for $3.99 @ 10k. Have a look at Digikey although they are out of this device but the pricing is there for smaller quantities. You might get a 128k Flash ARM7 cheaper than a 64k PIC althoung it has more than 10 times the performance :-)

It's attractive. What's the best deal for a PHY (only need 10-base-T)? ADM7001X? I guess the availability is a good match anyhow.
