The USB system specifies that a pull-up resistor be connected
on the D– pin of low-speed peripherals as shown in
Figure 6-24. To meet the USB 1.1 spec (section 7.1.6), which
states that the termination must charge the D– line from 0 to
2.0V in 2.5 µs, the total load capacitance on the D+/D– lines
of the low-speed USB device (Cypress device capacitance +

PCB trace capacitance + integrated cable capacitance) must
be less than 250 pF. As Cypress D+/D– transceiver input
capacitance is 20 pF max, up to 230 pF of capacitance is
allowed for in the low speed device’s integrated cable and
PCB. If the cable + PCB capacitance on the D+/D– lines will
be greater than approximately 230 pF, an external 3.3V
regulator must be used as shown in Figure 6-25.
