STR750 for General purpose and Vector drive 
The STR750 is the latest series in the STR7 family. It brings the best integration with a balanced peripheral set, USB, CAN and some key innovations like a clock failure detection and the advanced motor control timer. It is the only one to support both 3.3V and 5V, and it is also available in an extended temperature range (-40 to +105°C). This makes it a genuine general purpose microcontroller, suitable for a wide range of applications:
appliance, brushless motor drive
USB peripheral, UPS, alarm systems
programmable logic controller, circuit breaker, inverters
medical and portable equipment
