Flash Memory
The products in Z8 Encore! XP F0823 Series features either 8 KB (8192), 4 KB (4096),
2 KB (2048) or 1 KB (1024) of nonvolatile Flash memory with read/write/erase capability.
Flash Memory can be programmed and erased in-circuit by either user code or through the
On-Chip Debugger.
The Flash Memory array is arranged in pages with 512 bytes per page. The 512-byte page
is the minimum Flash block size that can be erased. Each page is divided into 8 rows of 64
bytes.
For program/data protection, the Flash memory is also divided into sectors. In the Z8
Encore! XP F0823 Series, these sectors are either 1024 bytes (in the 8 KB devices) or 512
bytes in size (all other memory sizes); each sector maps to a page. Page and sector sizes
are not generally equal.
The first two bytes of the Flash program memory are used as Flash Option bits. For more
information about their operation, see the Flash Option Bits chapter on page 146.
Table 79 describes the Flash memory configuration for each device in the Z8 Encore! XP
F0823 Series. Figure 20 displays the Flash memory arrangement.
