STM32 F-2 Family from STMicroelectronics is Cortex-M3 that runs as 120MHz

http://microcontroller.com/news/STM32_F-2.asp

The STM32 F-2 runs out of Flash at 120MHz. Has two USB 2.0B OTG ports, Ethernet, 528 
bytes OTP memory (who remembers what OTP means?) and plenty of peripherals.

The STM32 F-2 is from STMicroelectronics

Article contains a block diagram and a family roadmap.

Why do they make use of OTP instead of EEPROM? Does the lack of flexbility
is worth the silicon area?

It's not to save silicon area (probably uses more) but to store things like 
unique ID or MAC address which once assigned to a piece of equipment should 
never be changed.

One of the features seems to be a built-in cryptograpy accelerator.  The
OTP memory might be used for a unique crypto key for that piece of gear.

Article is updated with more detailed data on the ADC. It has three independent ADC that 
share 24 inputs:
