Software Data Protection (SDP)
The A49LF004 provides the JEDEC approved Software
Data Protection scheme for all data alteration operation, i.e.,
Program and Erase. Any Program operation requires the
inclusion of a series of three-byte sequences. The three-byte
load sequence is used to initiate the Program operation,
providing
optimal
protection
operations, e.g., during the system power-up or power-down.
Any Erase operation requires the inclusion of a six-byte load
sequence. The A49LF004 device is shipped with the
Software Data Protection permanently enabled. See Table 8
for the specific software command codes. During SDP
command sequence, invalid commands will abort the device
to Read mode, within T
RC
.
