28/40/44-Pin, Enhanced Flash-Based 8-Bit CMOS Microcontrollers with nanoWatt Technology

DEVICE OVERVIEW

The PIC16F882/883/884/886/887 is covered by this data sheet. The PIC16F882/883/886 is available in 28- pin PDIP, SOIC, SSOP and QFN packages. The PIC16F884/887 is available in a 40-pin PDIP and 44- pin QFN and TQFP packages. Figure 1-1 shows the block diagram of PIC16F882/883/886 and Figure 1-2 shows a block diagram of the PIC16F884/887 device. Table 1-1 and Table 1-2 show the corresponding pinout descriptions.

Program Memory Organization

The PIC16F882/883/884/886/887 has 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 wraparound 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).
