ISP1161A can operate at either 5 V or 3.3 V.
When using 5 V as ISP1161A’s power supply input, only V
connected to the 5 V power supply. An application with a 5 V power supply input is
shown in
its internal core. This internal 3.3 V can also be obtained from V
supply the 1.5 kΩ pull-up resistor of the DC side upstream port signal D_DP. The
signal D_DP is connected to the standard USB upstream port connector’s pin D+.
When using 3.3 V as the power supply input, the internal DC/DC regulator will be
bypassed. All four power supply pins (V
power supply input.
It is recommended that you connect all four power supply pins to the 3.3 V power
supply, as shown in
constraints, you must connect at least the V
supply.
For both 3.3 V and 5 V operation, all four power supply pins should be connected to a
decoupling capacitor.
