USB characteristics (Vcc = 2.7V to 5.5V, USBVcc = 3.0V to 3.6V, Vss = 0V, Ta = - 40C to + 85C) Parameter Symbol Pin name Conditions Value Unit Remarks MIN MAX Input charact- eristics Input High level voltage VIH UDP0, UDM0 - 2.0 USBVcc + 0.3 V *1 Input Low level voltage VIL - Vss - 0.3 0.8 V *1 Differential input sensitivity VDI - 0.2 - V *2 Different common mode input voltage VCM - 0.8 2.5 V *2 Output charact- erstics Output High level voltage VOH External pull-down resistance = 15kΩ 2.8 3.6 V *3 Output Low level voltage VOL External pull-up resistance = 1.5kΩ 0.0 0.3 V *3 Crossover voltage VCRS - 1.3 2.0 V *4 Rise time tFR Full Speed 4 20 ns *5 Fall time tFF Full Speed 4 20 ns *5 Rise/ fall time matching tFRFM Full Speed 90 111.11 % *5 Output impedance ZDRV Full Speed 28 44 Ω *6 Rise time tLR Low Speed 75 300 ns *7 Fall time tLF Low Speed 75 300 ns *7 Rise/ fall time matching tLRFM Low Speed 80 125 % *7 *1 : The switching threshold voltage of Single-End-Receiver of USB I/O buffer is set as within VIL (Max) = 0.8V, VIH (Min) = 2.0 V (TTL input standard). There are some hystereses to lower noise sensitivity. *2 : Use differential-Receiver to receive USB differential data signal. Differential-Receiver has 200 mV of differential input sensitivity when the differential data input is within 0.8 V to 2.5 V to the local ground reference level. Above voltage range is the common mode input voltage range. 0.2 0.8 1.0 2.5 Common mode input voltage [V] |
