Sector/Sector Block Protection and
Unprotection
(Note: For the following discussion, the term “sector”
applies to both sectors and sector blocks. A sector
block consists of two or more adjacent sectors that are
protected or unprotected at the same time (see Tables
8 and 9).
The hardware sector protection feature disables both
program and erase operations in any sector. The hard-
ware sector unprotection feature re-enables both pro-
gram and erase operations in previously protected
sectors. Sector protection/unprotection can be imple-
mented via two methods.
Table 8.
Top Boot Sector/Sector Block Addresses
for Protection/Unprotection
Table 9.
Addresses for Protection/Unprotection
Bottom Boot Sector/Sector Block
Sector protection/unprotection requires V
ID
on the RE-
SET# pin only, and can be implemented either in-sys-
tem or via programming equipment. Figure 2 shows
the algorithms and Figure 25 shows the timing dia-
gram. This method uses standard microprocessor bus
cycle timing. For sector unprotect, all unprotected sec-
tors must first be protected prior to the first sector un-
protect write cycle.
The sector unprotect algorithm unprotects all sectors
in parallel. All previously protected sectors must be in-
dividually re-protected. To change data in protected
sectors efficiently, the temporary sector unprotect
function is available. See “Temporary Sector Unpro-
tect”.
The device is shipped with all sectors unprotected.
AMD offers the option of programming and protecting
sectors at its factory prior to shipping the device
through AMD’s ExpressFlash Service. Contact an
AMD representative for details.
