1 - STM32F405RE / RC

2 - Analog comparator with DAC reference.

3 - Embedded ethernet phyter.

4 - PGA.

I would add also (from the point of view of a SW developer):

14. More alternate streams for peripherals using DMA, some peripherals don't have alternate streams at all. The F2/F4 implement this new flexible remapping mechanism, use all the gaps in those tables and let each peripheral have 2 or 3 alternatives.

15. Remove shared IRQs, it makes harder to write elegant code.

16. Increase the number of priorities in the CMx core to 32 or 64. This would increase the priority space to effectively use sub priorities.

17. If possible avoid differences among similar resources, lots of different timers, different U(S)ARTs etc, arrays of uniform resources make writing and maintaining support code easier.

18) Improved I2C peripheral, the current one requires polling in order to wait the end of STOP in master mode, not nice.

The nice thing about working with ARM MCUs today is the huge variety of devices available (from different manufacturers) that you do not need to use anything else.  Everything from stuff to replace cost-sensitive 8-bit apps (eg. LPC111x and STM32F100) to devices that nip at the the heels of ARM9/11 and Cortex-A application processors (such as the dual-core LPC43XX at 200+ MHz with support for external FLASH, SRAM, SDRAM etc.).  I use devices from Energy Micro (for extreme low-power apps), FreeScale Kinetis (which has recently announced a dual-core device with a Cortex-M4 and a Cortex-A4 AP), NXP and ST.  By not limiting myself to one brand/maker, there is always some available part that makes it the most cost-effective and efficient solution to the application at hand.

How about something like NXP's new Serial GPIO?

''...to 

interface to any non-standard serial interface or to mimic multiple standard serial interfaces.''

''...

combine general-purpose I/O with a timer/shift register and can be used to create orcapture multiple real-time serial data streams. Thiseliminates the need for code loops that manipulateGPIO in real time, and provides an easy-to-use alternative to CPU-intensive “bit banging�?. SGPIO 

can also be configured to provide designers an extra standard serial interface (UART, I2S, I2C, etc.).

''

I have not bothered to see how it's implemented, but it sounds interesting, however.

Here the wishlist from germany:

We hope some STM developers read it :)

SMO>> Do you have a web-link (news item ,datasheet, link to Freescale website) for this part? It sounds interesting but my search has proven fruitless.

Many thanks,

Probably a matter of search word combination ...

How about that:

Or that:

But seems it isn't so new after all.

Wholeheartedly agree.

And possibly add some FAQ section, so to not answer the same questions over and over.
