PIC10F220/222

MEMORY ORGANIZATION
The PIC10F220/222 memories are organized into pro-
gram memory and data memory. Data memory banks
are accessed using the File Select Register (FSR).
4.1
Program Memory Organization for
the PIC10F220
The PIC10F220 devices have a 9-bit Program Counter
(PC) capable of addressing a 512 x 12 program
memory space.
Only the first 256 x 12 (0000h-00FFh) for the
PIC10F220
are
physically
implemented
(see
Figure 4-1). Accessing a location above these
boundaries will cause a wrap-around within the first
256 x 12 space (PIC10F220). The effective Reset
vector is at 0000h, (see Figure 4-1). Location 00FFh
(PIC10F220) contains the internal clock oscillator
calibration value. This value should never be
overwritten.

4.2
Program Memory Organization for
the PIC10F222
The PIC10F222 devices have a 10-bit Program
Counter (PC) capable of addressing a 1024 x 12
program memory space.
Only the first 512 x 12 (0000h-01FFh) for the Mem-
High are physically implemented (see Figure 4-2).
Accessing a location above these boundaries will
cause a wrap-around within the first 512 x 12 space
(PIC10F222). The effective Reset vector is at 0000h,
(see Figure 4-2). Location 01FFh (PIC10F222) con-
tains the internal clock oscillator calibration value.
This value should never be overwritten.
