99 / 109 page  ST7263 99/109 7.8 COMMUNICATION INTERFACE CHARACTERISTICS The values given in the specifications of dedicated functions are generally not applicable for chips. Therefore, only the limits listed below are valid for the product. T = 0... +70°C, VDD - VSS = 5 V unless otherwise specified . 7.8.1 USB - Universal Bus Interface (Operating conditions T A = 0 to +70°C, V DD = 4.0 to 5.25V unless otherwise specified) Note 1: RL is the load connected on the USB drivers. Note 2: All the voltages are measured from the local ground potential. USB DC Electrical Characteristics Parameter Symbol Conditions Min. Max.
