XC87xCLM
Functional Description
3.3.1
Flash Bank Pagination
The XC87x product family offers Flash devices with either 64 Kbytes or 52 Kbytes of
embedded Flash memory. Each Flash device consists of a Program Flash (P-Flash) and
a single Data Flash (D-Flash) bank. P-Flash has 120 pages of 8 wordlines per page with
64 bytes per wordline. D-Flash has 64 pages of 2 wordlines per page with 32 bytes per
wordline. 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 page width and wordline of
each Flash bank.
The internal structure of each Flash bank represents a page architecture for flexible
erase capability. The minimum erase width is always a complete page. The D-Flash
bank is divided into smaller size for extended erasing and reprogramming capability;
even numbers for each page size are provided to allow greater flexibility and the ability
to adapt to a wide range of application requirements.
