USB PD SPECIFIC PARAMETERS Symbol Parameter TA = −40 to +855C TA = −40 to +1055C (Note 11) TJ = −40 to +1255C Unit Min Typ Max tHardReset If a Soft Reset message fails, a Hard Reset is sent after tHardReset of CRCReceiveTimer expiring − − 5 ms tHardReset Complete If the FUSB302B cannot send a Hard Reset within tHardResetComplete time because of a busy line, then a I_HARDFAIL interrupt is triggered − − 5 ms tReceive This is the value for which the CRCReceiveTimer expires. The CRCReceiveTimer is started upon the last bit of the EOP of the transmitted packet 0.9 − 1.1 ms tRetry Once the CRCReceiveTimer expires, a retry packet has to be sent out within tRetry time. This time is hard to separate externally from tReceive since they both happen sequentially with no visible difference in the CC output − − 75 ms tSoftReset If a GoodCRC packet is not received within tReceive for NRETRIES then a Soft Reset packet is sent within tSoftReset time. − − 5 ms tTransmit From receiving a packet, we have to send a GoodCRC in response within tTransmit time. It is measured from the last bit of the EOP of the received packet to the first bit sent of the preamble of the GoodCRC packet − − 195 ms Table 13.
