Flash Memory
PS026308-1207
The products in the Z8 Encore! F083A Series features either 4 KB (4096 bytes with
NVDS) or 8 KB (8192 bytes with NVDS) of non volatile Flash memory with read/write/
erase capability. The Flash memory is 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 is 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! F083A Series, each sector maps to one page (for 4 KB device), two pages (8 KB
device).
The first two bytes of the Flash program memory are used as Flash option bits. For more
