A/D channels (12 for PIC18F6X20 devices,
16 for PIC18F8X20)
I/O pins (52 on PIC18F6X20 devices, 68 on
PIC18F8X20)
External program memory interface (present
only on PIC18F8X20 devices)
The PIC18FXX20 devices are available in 64-pin and
80-pin packages. They are differentiated from each
other in five ways:
1.
FLASH program memory (32 Kbytes for
PIC18FX520 devices, 64 Kbytes for
PIC18FX620 devices, and 128 Kbytes for
PIC18FX720 devices)
Data RAM (2048 bytes for PIC18FX520
devices, 3840 bytes for PIC18FX620 and
PIC18FX720 devices)
All other features for devices in the PIC18FXX20 family
are identical. These are summarized in Table 1-1.
Block diagrams of the PIC18F6X20 and PIC18F8X20
devices are provided in Figure 1-1 and Figure 1-2,
respectively. The pinouts for these device families are
listed in Table 1-2.
