Feature
PIC16F722 to PIC16F720
This device has been designed to perform
to the parameters of its data sheet. It has
been tested to an electrical specification
designed to determine its conformance
with these parameters. Due to process dif-
ferences in the manufacture of this device,
this device may have different perfor-
mance characteristics than its earlier ver-
sion. These differences may cause this
device to perform differently in your appli-
cation than the earlier version of this
device.
The user should verify that the device
oscillator
expected. Adjusting the loading capacitor
values and/or the oscillator mode may be
required.
