Clarifications/Corrections to the Data Sheet:
In the Device Data Sheet (DS30605A), the following clar-
ifications and corrections should be noted:
1. Figure 3 and Figure 4 are additions to the data
sheet to show the area of operation. These figures
replace the Cross Reference of Device Specs for
Oscillator Modes Table in the Electrical Specifica-
tion section.
Figure 3 shows the voltage vs. frequency operation
for the PIC16CXXX devices. Devices marked with a
"-04" operate up to 4 MHz, while devices marked with
a "-20" operate up to 20 MHz. The entire shaded
region is the valid operating region.
Figure 4 shows the voltage vs. frequency operation
for the PIC16LCXXX devices. The devices marked
with a "-04" operate up to 4 MHz at the minimum sup-
plied voltage. The devices also operate at a higher
frequency (10 MHz) and at a higher voltage (3V). The
entire shaded region is the valid operating region.
2. The supply voltages and power-down currents
have been improved to the values shown in Table
1.
