Members
Members
Devices in the PIC18F8722 family are available in
64-pin and 80-pin packages. Block diagrams for the
two groups are shown in Figure 1-1 and Figure 1-2.
64-pin and 80-pin packages. Block diagrams for the
two groups are shown in Figure 1-1 and Figure 1-2.
The devices are differentiated from each other in five
ways:
ways:
1.
Flash program memory (48 Kbytes for
PIC18F6527/8527 devices, 64 Kbytes for
PIC18F6622/8622 devices, 96 Kbytes for
PIC18F6627/8627 devices and 128 Kbytes for
PIC18F6722/8722).

3.
I/O ports (7 bidirectional ports on 64-pin devices,
9 bidirectional ports on 80-pin devices).
9 bidirectional ports on 80-pin devices).
4.
External Memory Bus, configurable for 8 and
16-bit operation, is available on PIC18F8527/
8622/8627/8722 devices.
16-bit operation, is available on PIC18F8527/
8622/8627/8722 devices.
All other features for devices in this family are identical.
These are summarized in Table 1-2 and Table 1-2.
These are summarized in Table 1-2 and Table 1-2.
Like all Microchip PIC18 devices, members of the
PIC18F8722 family are available as both standard and
low-voltage devices. Standard devices with Enhanced
Flash memory, designated with an “F” in the part
number (such as PIC18F6627), accommodate an
