The maximum operating frequency given in 

 is limited by the embedded Flash access time when the processor 

is fetching code out of it. 

 gives the device maximum operating frequency depending on the field FWS of the 

MC_FMR register. This field defines the number of wait states required to access the embedded Flash memory.
The embedded Flash is fully tested during production test. The Flash contents are not set to a known state prior to 

shipment. Therefore, the Flash contents should be erased prior to programming an application. 

Notes: 1. Only the read operation is characterized between -40°C and +105°C. 

Other operations are characterized between -40°C and +85°C.

2. All bits in the word(s) are set to 0.
