3 REGISTER & MEMORY MAP
As shown in Figure 11, the MCU is capable of ad-
dressing 64 Kbytes of memories and I/O registers.
The available memory locations consist of 80
bytes of register locations, up to 5 Kbytes of RAM
and up to 32 Kbytes of user program memory. The
RAM space includes up to 256 bytes for the stack
from 0100h to 01FFh.
The highest address bytes contain the user reset
and interrupt vectors.
IMPORTANT:
Memory
locations
noted
“Re-
served” must never be accessed. Accessing a re-
served area can have unpredictable effects on the
device.

* Program memory and RAM sizes are product dependent (see Table –)
** The ST7 core is not able to read or write in the USB data buffer if the ST7265x is running at 6Mz in stan-
dalone mode.
