1.4 External connections
The following figure shows the recommended ex-
ternal connections for the device.
The VPP pin is only used for programming OTP
and EPROM devices and must be tied to ground in
user mode.
The 10 nF and 0.1 F decoupling capacitors on
the power supply lines are a suggested EMC per-
formance/cost tradeoff.
The external reset network (including the manda-
tory 1K serial resistor) is intended to protect the
device against parasitic resets, especially in noisy
environments.
Unused I/Os should be tied high to avoid any un-
necessary power consumption on floating lines.
An alternative solution is to program the unused
ports as inputs with pull-up.
