There are four devices (PIC16F873, PIC16F874, PIC16F876 and PIC16F877) covered by this datasheet. The PIC16F876/873 devices come in 28-pin packages and the PIC16F877/874 devices come in 40-pin packages. The Parallel Slave Port is not implemented on the 28-pin devices.

The following device block diagrams are sorted by pin number; 28-pin for Figure 1-1 and 40-pin for Figure 1-2.

The 28-pin and 40-pin pinouts are listed in Table 1-1 and Table 1-2, respectively.
