A random, secure ESN only within the Factor SecSi Sector
Customer code within the Customer SecSi Sector through the Spansion
TM
pro-
gramming service
Both a random, secure ESN and customer code through the Spansion
TM
pro-
gramming service.
Customers may opt to have their code programmed by Spansion through the
Spansion
TM
programming services. Spansion programs the customer’s code, with
or without the random ESN. The devices are then shipped from Spansion’s factory
with the Factory SecSi Sector and Customer SecSi Sector permanently locked.
Contact your local representative for details on using Spansion
TM
programming
services.
Customer SecSi Sector
If the security feature is not required, the Customer SecSi Sector can be treated
as an additional Flash memory space. The Customer SecSi Sector can be read
any number of times, but can be programmed and locked only once. Note that
the accelerated programming (ACC) and unlock bypass functions are not avail-
able when programming the Customer SecSi Sector, but reading in Banks 1
through 15 is available. The Customer SecSi Sector is located at addresses
000080h–0000FFh.
The Customer SecSi Sector area can be protected by writing the SecSi Sector
Protection Bit Lock command sequence.
Once the Customer SecSi Sector is locked and verified, the system must write the
Exit SecSi Sector Region command sequence to return to reading and writing the
remainder of the array.
The Customer SecSi Sector lock must be used with caution since, once locked,
there is no procedure available for unlocking the Customer SecSi Sector area and
none of the bits in the Customer SecSi Sector memory space can be modified in
any way.
SecSi Sector Protection Bit
The Customer SecSi Sector Protection Bit prevents programming of the Customer
SecSi Sector memory area. Once set, the Customer SecSi Sector memory area
contents are non-modifiable.
Common Flash Memory Interface (CFI)
The Common Flash Interface (CFI) specification outlines device and host system
software interrogation handshake, which allows specific vendor-specified soft-
ware algorithms to be used for entire families of devices. Software support can
then be device-independent, JEDEC ID-independent, and forward- and back-
ward-compatible for the specified flash device families. Flash vendors can
standardize their existing interfaces for long-term compatibility.
This device enters the CFI Query mode when the system writes the CFI Query
command, 98h, to address (BA)555h any time the device is ready to read array
data. The system can read CFI information at the addresses given in
