Functional Description

V1.2, 2009-07
Table 19 shows the Flash data retention and endurance targets.
3.3.1
Flash Bank Sectorization
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)
and Data Flash (D-Flash) bank(s) with different sectorization shown in Figure 11. Both
types can be used for code and data storage. The label “Data” 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 32-Kbyte Flash device consists of 6 P-Flash and 2 D-Flash banks, while the 24-
Kbyte Flash device consists of also of 6 P-Flash banks but with the upper 2 banks only
2 Kbytes each, and only 1 D-Flash bank. The XC886/888 ROM devices offer a single 4-
Kbyte D-Flash bank.
The P-Flash banks are always grouped in pairs. As such, the P-Flash banks are also
sometimes referred to as P-Flash bank pair. Each sector in a P-Flash bank is grouped
with the corresponding sector from the other bank within a bank pair to form a P-Flash
bank pair sector.
Table 19
Flash Data Retention and Endurance (Operating Conditions apply)
Retention
Endurance1)
1) One cycle refers to the programming of all wordlines in a sector and erasing of sector. The Flash endurance
data specified in Table 19 is valid only if the following conditions are fulfilled:
- 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.

2) 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.
