The products in the Z8 Encore! XP F082A Series feature a nonvolatile Flash memory of
8 KB (8192), 4 KB (4096), 2 KB (2048 bytes), or 1 KB (1024) with read/write/erase capa-
bility. The Flash Memory can be programmed and erased in-circuit by user code or
through the On-Chip Debugger. The features include:
•
•
•
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 or data protection, the Flash memory is also divided into sectors. In the Z8
Encore! XP F082A Series, these sectors are either 1024 bytes (in the 8 KB devices) or 512
bytes (all other memory sizes) in size. Page and sector sizes are not generally equal.
The first 2 bytes of Flash Program memory are used as Flash option bits. For more infor-
mation about their operation, see the
Table 78 describes the Flash memory configuration for each device in the Z8 Encore! XP
F082A Series. Figure 21 displays the Flash memory arrangement.
