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 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.
