The PIC16F688 is covered by this data sheet. It is available in 14-pin PDIP, SOIC, TSSOP and QFN packages. The PIC16F688 has a 13-bit program counter capable of addressing a 4K x 14 program memory space. Only the first 4K x 14 (0000h-01FFF) for the PIC16F688 is physically implemented. Accessing a location above these boundaries will cause a wrap-around within the first 4K x 14 space.
