The USB system specifies that a pull-up resistor be connected
on the D– pin of low-speed peripherals as shown in Figure 6-
27. To meet the USB 1.1 spec (section 7.1.6), which states that
the termination must charge the D– line from 0 to 2.0 V in
2.5 s, 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 capac-
itance is 20pF 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 6-28.
