I would rate this as a MICROPROCESSOR for the uPs/uCs/Peripheral ICs type. As a whole, there are 42 terminations. A 1.9V voltage supply should be used to turn on and run the cpu microprocessor. A maximum supply current of 3.6V can be achieved by the microprocessor. Be sure not to miss the following additional features of this microprocessor: ALSO WORKING TWO CELL MODE AT 2.4V NOM. SUPPLY.. There should be a value over -40°C in the operating environment.
