PIC18LC242T-I/JW301 Datasheet - Microchip Technology

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.

High Performance RISC CPU:
