The STM32 F4 series is the world�s highest performance Cortex�-M microcontroller � 168 MHz (Cortex-M4 with FPU) CPU, 210 DMIPS, 363 Coremark score;

The STM32 F4 is available now and ST will be distributing STM32 F4 Discovery Kits at the Embedded Systems Conference in Boston, Sept 27-28;

The STM32 F4 series extends the STM32 portfolio and now has 250+ compatible devices already in production, including the F1 series, F2 series and ultra-low-power L1 series

The STM32 F4 reinforces ST�s leadership in Cortex-M microcontrollers, with 45% world market share by units (cumulated 2007-Q1 2011 period according to ARM Cortex-M unit shipments reporting)

Continue Releasing your Creativity with our STM32 !

Cheers,

STOne-32.

Awesome - Cortex-M4 is coming. We've been waiting for that.

STM-one, can you tell the web people their website appears broken? I followed the links to request a STM32 F4 Discovery board. On this page:

http://www.samplecomponents.com/scripts/samplecenter.dll

it keeps throwing up an error message at the top of the page:

Additional Engineer Email: Invalid email address

There's no field on the page for an additional email. The page just has a few fields asking about project information (project name, application, quantity, preferred distributor, etc). Looks like someone made a copy&paste error.

Thanks.

Hello,

1 - Are they 100% pin to pin comptable with STM32F2xx?

2 - Are LQFP64 engineering samples available yet?

Where can I find more information about the FPU (number of clock cycles for each operation, operations supported, etc)?

Thomas.

PS : And price increase compared to the STM32F2 series (same flash size, same package size).

Hello,

Core STM32F4xx is interesting thanks to presence fpu which descriptions unfortunately are not present on site ST

For ARM documentation, try the ARM site, the ST implementation details are periphery to the core.

Thanks clive1.

Thought that there will be a clone PM0056 for STM32F4xx

I really like the STM32F (particularly the STM32F100 parts as a viable replacement for 8/16 parts) but the FreeScale Kinetis offers better value, features and variety compared to the STM32F4xxx.

Like RM0090? I posted these over in the STM32F4 forum, try these

''Continue Releasing your Creativity with our STM32 !''

 

 

But only, apparently, if you're in North America!

:(

I note that free Discovery kits are available - but only to

North America!

:(

 

 

Come on, ST - there's more to the world than just North America!
