DEVICE OVERVIEW
This document contains device-specific information for
the following four devices:
1.
2.
3.
4.
PIC18C242
PIC18C252
PIC18C442
PIC18C452
The following two figures are device block diagrams
sorted by pin count; 28-pin for Figure 1-1 and 40-pin for
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.
