    DEVICE OVERVIEW
    This document contains device specific information for
    the following devices:
    PIC18F248
    PIC18F258
    PIC18F448
    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
    program 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.
