Flash Memory
PS025111-1207
The products in the Z8 Encore!
NVDS), 2 KB (2048 bytes with NVDS), 4 KB (4096 bytes with NVDS), 8 KB (8192
bytes with NVDS) or 12 KB (12288 bytes with no NVDS) of non volatile Flash memory
with read/write/erase capability. The 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 eight rows
of 64 bytes.
For program/data protection, the Flash memory is also divided into sectors. In the Z8
Encore! F0830 Series, each sector maps to one page (for 1 KB, 2 KB and 4 KB devices),
two pages (8 KB device) or three pages (12 KB device).
The first two bytes of the Flash program memory is used as Flash option bits. For more
information, see
Table 66
F0830 Series.
