PIC18CXX2
1.0 DEVICE OVERVIEW
This document contains device specific information for
the following four devices:
1. PIC18C242
2. PIC18C252
3. PIC18C442
4. PIC18C452
These devices come in 28-pin and 40-pin packages.
The 28-pin devices do not have a Parallel Slave Port
(PSP) implemented and the number of Analog-to-
Digital (A/D) converter input channels is reduced to 5.
An overview of features is shown in Table 1-1.
The following two figures are device block diagrams
sorted by pin count: 28-pin for Figure 1-1 and 40-pin for
Figure 1-2. The 28-pin and 40-pin pinouts are listed in
Table 1-2 and Table 1-3, respectively.
