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 ;)

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. Best regards, Spehro Pefhany -- "it's the network..."

Claims $4.99/10K, so likely to be at the cheaper end of your price. http://www.asix.com.tw/products.php?op=pItemdetail&PItemID=91;72;103 http://www.eeproductcenter.com/micro/review/showArticle.jhtml?articleID=189401458 -jg

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.

Try the Freescale MCF52234 32 bits 256k flash, 32K ram, a/d i2c, spi, uarts, timers anethernet MAC and PHY. Paul

"The Journey is the reward" > s...@interlog.com Info for manufacturers:http://www.trexon.com > Embedded software/hardware/analog Info for designers: http://www.speff.comHi, 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 :-) Robert

ADM7001X? I guess the availability is a good match anyhow. Best regards, Spehro Pefhany -- "it's the network..."
