5 / 296 page © 7/99 Microchip Technology Inc. Preliminary DS39026B-page 5 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 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.
