MEMORY ORGANIZATION
FIGURE 2-2:
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).

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.
