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).
