PIC16F723A-I/SO is a 28-Pin Flash Microcontroller with XLP Technology. The PIC16F723A-I/SO has a 13-bit program counter capable of addressing a 2K x 14 program memory space for the PIC16F723A-I/SO and a 4K x 14 program memory space for the PIC16(L)F723A (0000h-0FFFh). Accessing a location above the memory boundaries for the PIC16(L)F722A will cause a wrap-around within the first 2K x 14 program memory space. Accessing a location above the memory boundaries for the PIC16(L)F723A will cause a wrap-around within the first 4K x 14 program memory space. The Reset vector is at 0000h and the interrupt vector is at 0004h.
