PIC16F882/883/884/886/887

2.0 MEMORY ORGANIZATION

2.1 Program Memory Organization

The PIC16F882/883/884/886/887 devices have a 13-bit

program counter capable of addressing a 2K x 14

(0000h-07FFh) for the PIC16F882, 4K x 14 (0000h-

0FFFh) for the PIC16F883/PIC16F884, and 8K x 14

(0000h-1FFFh) for the PIC16F886/PIC16F887 program

memory space. Accessing a location above these

boundaries will cause a wrap-around within the first 8K x

14 space. The Reset vector is at 0000h and the interrupt

vector is at 0004h (see Figures 2-2 and 2-3).
