Description
supply voltage for digital I/O pins (1.65 V to 3.6 V); when V
the DP and DM pins are in 3-state; this supply pin is totally independent of
V

Connect a 1 F-to-10 F decoupling capacitor (4.7 F capacitor is used on the
ISP1102 evaluation board)

positive USB data bus connection (analog, differential)

not connected
internal regulator option: regulated supply voltage output (3.0 V to 3.6 V) during
5 V operation; a decoupling capacitor of at least 0.1 F is required
regulator bypass option: used as a supply voltage input (3.3 V
operation
internal regulator option: supply voltage input (4.0 V to 5.5 V); can directly be
connected to USB line V
regulator bypass option: connect to VREG3V3
pull-up supply voltage (3.3 V
(full-speed)
This pin function is controlled by the SOFTCON input:
SOFTCON = LOW — VPU3V3 floating (high-Z); ensures zero pull-up current
SOFTCON = HIGH — VPU3V3 = 3.3 V; internally connected to VREG3V3
software controlled USB connection input; a HIGH level applies 3.3 V to
pin VPU3V3, which is connected to an external 1.5 k pull-up resistor; this allows
USB connect or disconnect signaling to be controlled by software
