Черт посмотрел сейчас на даташит там не 72 а 70, а UM 60, Интересно теперь, где правда написана? кто больше 60 делал?
Да всяко 70, и в еррате про 70

Vdd.1Device may not work properly under increased power consumption conditions
Introduction: From the Vdd1V8 pin to the ARM7 core, there is a voltage drop. This voltage drop increases with higher currents (or higher power consumption). Higher system frequency and/or faster peripherals increase power consumption thereby increasing the voltage drop from the Vdd1V8 pin to the core.
Problem: Under increased power consumption conditions, the device may not work properly. The likelihood of the problem showing up increases if the device is run at higher speeds (approaching 70MHz) and/or if the peripherals are running at close to system frequency speed (i.e If the APBDIV register is set to a value lower than 4 which would imply that the peripherals are run faster than 1/4 of the system frequency).
Also, having a lower voltage on Vdd1V8 pin (e.g. below 1.8V) can cause this issue to surface.
Work-around: Increase the voltage on Vdd1V8 to 1.95V. It is not harmful to the device if this voltage reaches 2V.
