MEMORY ORGANIZATION
3.1
Program Memory Organization
The PIC16F62X has a 13-bit program counter capable
of addressing an 8K x 14 program memory space. Only
the first 1K x 14 (0000h - 03FFh) for the PIC16F627
and 2K x 14 (0000h - 07FFh) for the PIC16F628 are
physically implemented. Accessing a location above
these boundaries will cause a wrap-around within the
first 1K x 14 space (PIC16F627) or 2K x 14 space
(PIC16F628). The RESET vector is at 0000h and the
interrupt vector is at 0004h (Figure 3-1).

AND STACK
3.2
Data Memory Organization
The data memory (Figure 3-2) is partitioned into four
banks, which contain the general purpose registers and
the Special Function Registers (SFR). The SFR’s are
located in the first 32 locations of each Bank. Register
locations 20-7Fh, A0h-FFh, 120h-14Fh, 170h-17Fh
and 1F0h-1FFh are general purpose registers
implemented as static RAM.
The Table below lists how to access the four banks of
registers:
Addresses F0h-FFh, 170h-17Fh and 1F0h-1FFh are
implemented as common RAM and mapped back to
addresses 70h-7Fh.
3.2.1
GENERAL PURPOSE REGISTER
FILE
The register file is organized as 224 x 8 in the
PIC16F62X. Each is accessed either directly or
indirectly through the File Select Register FSR (See
Section 3.4).
