40+ MIPS low cost MCU

Hi

I am looking for simple cheap thumb MCU requirements

1 40+ MIPS
2 16 + IO pins
3 single cycle GPIO port
4 16+ KB flash (32k if mcu is 32 bit one)
5 optionally FS USB device
6 preffered onchip high speed oscillator

low cost < 2.0 usd (little more if usb is present)

SAM7 have slow GPIO
the microchips new MIPS based one, dont have pricing and gpio speed
info

any chip that fits the profile?

Antti would be real glad for any hints

TMS320F2401 or the small DSPs from FreeScale come to mind.
What are you trying to build?

STM32 $1.80 without FS USB, a little more with

wau you have nice prices for for STM32 if you did give real prices
(not advertied 1Mio/year pricing or something)

digikey price indicator for them is around 3.5 usd, even more then
luminary stuff

i was almost thinking STM32 myself but assumed it to be out of price
range

the smallest STM32 look pretty neat in QFN36 package
but this package not available on digikey yet :(

anyway nice to see that STM32 claims 18mhz SPI master-serial and 18
mhz GPIO toggle rates,
similar info is not always easy to find by first look

ah, about the function needed - its custom 8 bit parallel interfaces
clocked at 4MHz

so about 40 MIPS is required as minimum (assumed 1 clock GPIO access)


thansk for suggestions, but eh maybe there some more that fit the
bill ?

PIC32 GPIO speed is very good,  at 72 Mhz you can toggle i/o pins.
see:

http://forum.microchip.com/tm.aspx?m=293191&mpage=4

for now no USB..

yes looked PIC32 too, but
1) NO SILICON offered by digikey.. this is good-bad indicator of
availability
2) I assume the pricing be outside 2 usd range too much

even the STM32 doesnt seem to have the QFN36 variants shipping yet :(
avnet pricing for smallest STM32 is 2.8 USD qty 1 what is damn good
already
sure i want the pricing below that, but 2.8 qty pricing is good sign
that target
price can met for STM32

for PIC32 i bet it takes another 3 to 6 month to get any silicon and
somewhat correct pricing
(I maybe wrong, maybe the PIC32 pricing will be known and wonderful
for this christmas already)


Antti who is still looking for more alternatives

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

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

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

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
