Flash Memory
The products in the Z8 Encore! XP F64xx Series feature up to 64 KB (65,536 bytes) of
non-volatile Flash memory with read/write/erase capability. The Flash memory can be
programmed and erased in-circuit by either user code or through the On-Chip Debugger.
The Flash memory array is arranged in 512 byte per page. The 512 byte page is the mini-
mum Flash block size that can be erased. The Flash memory is also divided into 8 sectors
which can be protected from programming and erase operations on a per sector basis.
Table 90 describes the Flash memory configuration for each device in the Z8 Encore! XP
F64xx Series. Table 91 lists the sector address ranges. Figure 35 displays the Flash mem-
ory arrangement.
