PIC18FXX8
1.0 DEVICE OVERVIEW
This document contains device specific information for
the following devices:
1. PIC18F248
2. PIC18F258
3. PIC18F448
4. PIC18F458
These devices are available in 28-pin, 40-pin and
44-pin packages. They are differentiated from each
other in four ways:
1. PIC18FX58 devices have twice the FLASH pro-
gram memory and data RAM of PIC18FX48
devices (32 Kbytes and 1536 bytes vs.
16 Kbytes and 768 bytes, respectively).
2. PIC18F2X8 devices implement 5 A/D channels,
as opposed to 8 for PIC18F4X8 devices.
3. PIC18F2X8 devices implement 3 I/O ports,
while PIC18F4X8 devices implement 5.
4. Only PIC18F4X8 devices implement the
Enhanced CCP module, analog comparators
and the Parallel Slave Port.
All other features for devices in the PIC18FXX8 family,
including the serial communications modules, are
identical. These are summarized in Table 1-1.
Block diagrams of the PIC18F2X8 and PIC18F4X8
devices are provided in Figure 1-1 and Figure 1-2,
respectively. The pinouts for these device families are
listed in Table 1-2.
