3.3.1
The XC886/888 product family offers Flash devices with either 24 Kbytes or 32 Kbytes
of embedded Flash memory. Each Flash device consists of Program Flash (P-Flash)
bank(s) and a single Data Flash (D-Flash) bank with different sectorization shown in
Figure
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.
The XC886/888 ROM devices offer a single 4-Kbyte D-Flash bank.
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.
