Flash Memory
The products in the Z8 Encore! F0830 Series features either 1 KB (1024 bytes with
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 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 eight rows
of 64 bytes.
For program/data protection, 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 Flash program memory is used as Flash option bits. For more infor-
mation, see the Flash Option Bits chapter on page 124.
Table 69 lists the Flash memory configuration for each device in the Z8 Encore! F0830
Series. Figures 14 through 18 display the memory arrangements for each Flash memory
size.
