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.

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.

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

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
