2.13 GHz is the frequency of the CPU. 775 pin functions are described in the datasheets. Injecting pins into the embedded microprocessor body results in 775 pins. In many applications, this CPU is mounted with a Surface Mount bus. A voltage higher than 1.5 V shouldn't be used in a normal situation. It is recommended that the lowest voltage be fed to the micro processor is 1.14 V.
