Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector protection verification,
through identifier codes output on DQ7–DQ0. This
mode is primarily intended for programming equip-
ment to automatically match a device to be pro-
grammed 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
ID
(8.5 V to 12.5 V) on address A9.
Addresses A6, A1, and A0 must be as shown in
Table 4, on page 19
. In addition, when verifying sector
protection, the sector address must appear on the ap-
propriate highest order address bits (see
Table 2, on
page 11
and
Table 3, on page 15
).
Table 4
shows the
remaining address bits that are don’t care. When all
necessary bits have been set as required, the pro-
gramming equipment may then read the correspond-
ing identifier code on DQ7–DQ0.
To access the autoselect codes in-system, the host
system can issue the autoselect command via the
command register, as shown in
Table 10, on page 30
.
This method does not require V
ID
. Refer to the
“Au-
toselect Command Sequence” on page 26
section for
more information.
Table 4.
Am29LV652D Autoselect Codes, (High Voltage Method)
Legend:
L = Logic Low = V
IL
, H = Logic High = V
IH
, SA = Sector Address, X = Don’t care.
Notes:
1. CE# can be replaced with CE2# when referring to the second die in the package.
2. The device ID’s used for the Am29LV652 are the same as the Am29LV065, because the Am29LV652 uses two Am29LV065
dice and appears to the system as two Am29LV065 devices.
