The ISP1160 can operate at either 5 V or 3.3 V.
When using 5 V as the ISP1160’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
for its internal core. This internal 3.3 V can also be obtained from V
When using 3.3 V as the power supply input, the internal DC/DC regulator will be
bypassed. All four power supply pins (V
used as 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 V
For both 3.3 V and 5 V operation, all four power supply pins should be connected to a
decoupling capacitor.
The ISP1160 has a crystal oscillator designed for a 6 MHz parallel-resonant crystal
(fundamental). A typical circuit is shown in
signal of 6 MHz can be applied to input XTAL1, while leaving output XTAL2 open. See
