11. Power supply
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
CC
(pin 56) can be
connected to the 5 V power supply. An application with a 5 V power supply input is
shown in
Figure 29
. The ISP1160 has an internal DC/DC regulator to provide 3.3 V
for its internal core. This internal 3.3 V can also be obtained from V
REG(3V3)
(pin 58).
When using 3.3 V as the power supply input, the internal DC/DC regulator will be
bypassed. All four power supply pins (V
CC
, V
REG(3V3)
, V
HOLD1
and V
HOLD2
) can be
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
Figure 30
. If, however, you have board space (routing area)
constraints, you must connect at least V
CC
and V
REG(3V3)
to the 3.3 V power supply.
For both 3.3 V and 5 V operation, all four power supply pins should be connected to a
decoupling capacitor.
12. Crystal oscillator
The ISP1160 has a crystal oscillator designed for a 6 MHz parallel-resonant crystal
(fundamental). A typical circuit is shown in
Figure 31
. Alternatively, an external clock
signal of 6 MHz can be applied to input XTAL1, while leaving output XTAL2 open. See
Figure 32
. The 6 MHz oscillator frequency is multiplied to 48 MHz by an internal PLL.
