Flash Memory
Overview
The products in the Z8 Encore!^® 64K Series feature up to 64KB (65,536 bytes) of non-
volatile Flash memory with read/write/erase capability. The Flash memory can be pro-
grammed 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 88 describes the Flash memory configuration for each device in the 64K Series.
Table 89 lists the sector address ranges. Figure 35 illustrates the Flash memory arrange-
ment.
