3.3.1
The SAA-XC866 product family offers four Flash devices with either 8 Kbytes or
16 Kbytes of embedded Flash memory. These Flash memory sizes are made up of two
or four 4-Kbyte Flash banks, respectively. Each Flash device consists of Program Flash
(P-Flash) bank(s) and a single Data Flash (D-Flash) bank with different sectorization
shown in
neither implies that the D-Flash is mapped to the data memory region, nor that it can only
be used for data storage. It is used to distinguish the different Flash bank sectorizations.
Figure 11
The internal structure of each Flash bank represents a sector architecture for flexible
erase capability. The minimum erase width is always a complete sector, and sectors can
be erased separately or in parallel. Contrary to standard EPROMs, erased Flash
memory cells contain 0s.
The D-Flash bank is divided into more physical sectors for extended erasing and
reprogramming capability; even numbers for each sector size are provided to allow
greater flexibility and the ability to adapt to a wide range of application requirements.
