The 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.
The XC866 ROM devices offer a single 4-Kbyte D-Flash bank.
Data Sheet
One cycle refers to the programming of all wordlines in a sector and erasing of sector. The Flash endurance
data specified in
- the maximum number of erase cycles per Flash sector must not exceed 100,000 cycles.
- the maximum number of erase cycles per Flash bank must not exceed 300,000 cycles.
- the maximum number of program cycles per Flash bank must not exceed 2,500,000 cycles.
If no Flash is used for data, the Program Flash size can be up to the maximum Flash size available in the
device variant. Having more Data Flash will mean less Flash is available for Program Flash.
