9 / 108 page PIC16C712/716 © 1999 Microchip Technology Inc. Preliminary DS41106A-page 9 2.0 MEMORY ORGANIZATION There are two memory blocks in each of these PICmicro® microcontroller devices. Each block (Pro- gram Memory and Data Memory) has its own bus so that concurrent access can occur. Additional information on device memory may be found in the PICmicro ™ Mid-Range Reference Manual, (DS33023). 2.1 Program Memory Organization The PIC16C712/716 has a 13-bit program counter capable of addressing an 8K x 14 program memory space. PIC16C712 has 1K x 14 words of program memory and PIC16C716 has 2K x 14 words of program memory. Accessing a location above the physically implemented address will cause a wraparound. The reset vector is at 0000h and the interrupt vector is at 0004h.
