PIC18F6525/6621/8525/8621
1.2 Details on Individual Family
Members
The PIC18F6525/6621/8525/8621 devices are avail-
able in 64-pin (PIC18F6525/6621) and 80-pin
(PIC18F8525/8621) packages. They are differentiated
from each other in four ways:
1. Flash program memory (48 Kbytes for
PIC18F6525/8525 devices; 64 Kbytes for
PIC18F6621/8621 devices).
2. A/D channels (12 for PIC18F6525/6621
devices; 16 for PIC18F8525/8621 devices).
3. I/O ports (7 on PIC18F6525/6621 devices; 9 on
PIC18F8525/8621 devices).
4. External program memory interface (present
only on PIC18F8525/8621 devices)
All other features for devices in the PIC18F6525/6621/
8525/8621 family are identical. These are summarized
in Table 1-1.
Block diagrams of the PIC18F6525/6621 and
PIC18F8525/8621 devices are provided in Figure 1-1
and Figure 1-2, respectively. The pinouts for these
device families are listed in Table 1-2.
