Nobody listed the LPC2103 yet, definitely fits your bill, is lower cost than the STM32 and more mature. I admit, the STM32 is more sexy but you get a lot of performance out of the LPC2103 as well and it has the fast I/O feature which offers single cycle I/O. At Digikey the 2103 is approx. 10% lower cost than the smallest STM32. May be an additional advantage, the LPC2102 could fit your requirements as well and is another 10% less. Drop-in compatible to the LPC2103. Besides the NXP website, you can also find information on the LPC2000 devices on this web site http://www.lpc2000.com/ Robert Robert

Hi thanks again to all for suggestions I have some experience with luminary, but there are 3 missing things - no onchip osc - no option with usb - no qfn packages the AVR32 with 60mhz GPIO access is truly nice, but need pricing to be good as well for the moment the STM32 looks like its getting selected Antti

Production parts of the AVR32 AT32uC3B064 should have 60 MHz operation and 60 MHz I/O toggle. Should be around 75 MIPS. 28 I/O pins in the 48 pin package. Smallest devices is 64 kB flash/16 kB SRAM which will of course affect price.

You shouldn't see the wait states because of the caching (I don't remember what they call it, but it is a cache in effect). You definitely do NOT want to run out of RAM - the STM32 is not optimized for this and the speed is much slower. But it runs very nice from flash. Eric

The Luminary LM3S600-IQN50 is a good candidate: 32K single cycle Flash, 50MHz core, max 28 GPIOs. Only the internal high-speed oscillator is missing. Suggested resale is USD 2.01 @ 1K pieces. The advantage of Luminary is that their core is really running at 50MHz, while executing from Flash. No wait states necessary. Also, the Luminary parts are all available in production quantities, and have even more SRAM than their ST counterparts. Also no multiplexing of peripherals: all peripherals have their own pins (although muxed with GPIOs). Mark

40 "mips" depend of the definition of "Mips" With full speed USB, the following Freescale devices can fit your needs at 3-4 USD: 8 bits microcontrolleur : MC9S08JM60 32 bits microcontrolleur : MCF52212 Consider also the cost of the developpement tools (IDE, Debugger), very low for freescale devices thierry

yep, my opinion STM32 is current state of art for small high speed/ cheap micro, ...32 bits,tiny, runs down to 2 volts, low active AND standby power, internal high/low speed clocks, hardware division, lots of RAM, 12 bit a/d, DMA blah blah blah...next month it will be something different. Small QFN went active a few weeks ago, also a smaller package (less then 5x5mm) may be coming next year

I think USD$1.8 is for 10K of the 36MHz parts, but you need the 72MHz for USB anyway.

eh, thanks another time for clarification, yes with 2,8 avnet online pricing i did assume 1.8 for 10k volume it defenetly fits the bill, actually the usb version maybe even better already ordered tqfp48 samples, hoping that the qfn would also be available JAN2008 ;) eh, the STM32 outperforms my needs even as it has nice DMA engine so the cpu performance could be even lower it looks that the DMA engine can handle most of the protocol needs Antti

it's 10K distributor pricing, not retail (digikey) price, since you didn't mention quantities, I had to guess 18Mhz GPIO is running from FLASH at 72Mhz, 2 wait states, maybe run your code from zero wait state ram the smallest package was added later, it now seems active, guess digikey/mouser should see it soon
