A29L040 Series  
Autoselect Mode  
The autoselect mode provides manufacturer and device  
identification, and sector protection verification, through  
identifier codes output on I/O7 - I/O0. This mode is primarily  
intended for programming equipment to automatically match  
appropriate highest order address bits. Refer to the  
corresponding Sector Address Tables. The Command  
Definitions table shows the 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 identifier code on I/O7 - I/O0.To access the  
autoselect codes in-system, the host system can issue the  
autoselect command via the command register, as shown in  
the Command Definitions table. This method does not  
require VID. See "Command Definitions" for details on using  
the autoselect mode.  
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 VID (11.5V to 12.5 V) on address pinA9. Address  
pins A6, A1, and AO must be as shown in Autoselect Codes  
(High Voltage Method) table. In addition, when verifying  
sector protection, the sector address must appear on the

Sector Protection/Unprotection  
Write Pulse "Glitch" Protection  
The hardware sector protection feature disables both  
program and erase operations in any sector. The hardware  
sector unprotection feature re-enables both program and  
erase operations in previously protected sectors.  
Noise pulses of less than 5ns (typical) on  
do not initiate a write cycle.

Logical Inhibit  
Sector protection/unprotection must be implemented using  
programming equipment. The procedure requires a high  
voltage (VID) on address pin A9 and the control pins.  
The device is shipped with all sectors unprotected.  
Write cycles are inhibited by holding any one of

Hardware Data Protection  
CE  
The requirement of command unlocking sequence for  
programming or erasing provides data protection against  
inadvertent writes (refer to the Command Definitions table).  
In addition, the following hardware data protection measures  
prevent accidental erasure or programming, which might  
otherwise be caused by spurious system level signals during  
VCC power-up transitions, or from system noise. The device  
is powered up to read array data to avoid accidentally writing  
data to the array.
