Autoselect Mode
The autoselect mode provides manufacturer and device identification, and sector
protection verification, through identifier codes output on DQ7–DQ0. This mode
is primarily intended for programming equipment to automatically match a device
to be programmed with its corresponding programming algorithm. However, the
autoselect codes can also be accessed in-system through the command register.
When using programming equipment, the autoselect mode requires V
dress pin A9. Address pins must be as shown in Table
when verifying sector protection, the sector address must appear on the appro-
priate highest order address bits (see Table 3). Table
remaining address bits that are don’t care. When all necessary bits have been set
as required, the programming equipment may then read the corresponding iden-
tifier code on DQ7–DQ0. However, the autoselect codes can also be accessed in-
system through the command register, for instances when the device is erased
or programmed in a system without access to high voltage on the A9 pin. The
command sequence is illustrated in Table 17. Note that if a Bank Address (BA)
(on address bits PL127J: A22–A20, PL064J: A21–A19, PL032J: A20–A18) is as-
serted during the third write cycle of the autoselect command, the host system
can read autoselect data that bank and then immediately read array data from
the other bank, without exiting the autoselect mode.
To access the autoselect codes in-system, the host system can issue the autose-
lect command via the command register, as shown in Table 17. This method does
not require V
information.
