Autoselect Mode
IL
IH
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
must be as shown in
on the appropriate highest order address bits.
When all necessary bits have been set as required, the programming equipment may then read the
corresponding identifier code on DQ7–DQ0. However, the autoselect codes can also be accessed in-system
through the command register, for instances when the S29JL032J is erased or programmed in a system
without access to high voltage on the A9 pin. The command sequence is illustrated in
Note that if a Bank Address (BA) on address bits A20, A19 and A18 is asserted during the third write cycle of
the autoselect command, the host system can read autoselect data from that bank and then immediately read
array data from another bank, without exiting the autoselect mode.
To access the autoselect codes in-system, the host system can issue the autoselect command via the
command register, as shown in
