Command Definitions
Revision D (February 22, 2000)
Table 14, Command Definitions: The SecSi Sector In-
dicator Bit values have changed from 80h and 00h to
81h and 01h, respectively.
Global
The Am29DL16x family has migrated to a new 0.23
µm process technology, which is indicated by a “D” in
the ordering part number. All references in this docu-
ment have been changed to reflect the new process.
AC Characteristics
Read-only Operations table: Changed parameter tDF to
16 ns for all speed options. Added Note 3.
Distinctive Characteristics
Revision D+2 (September 4, 2000)
Under “Performance Characteristics,” the typical accel-
erated programming time was changed to match the
AC tables.
Deleted remaining references to 80 ns speed option,
which was officially removed in Revision D+1. Cor-
rected references to Am29DL16xC, which officially
changed to Am29DL16xD in Revision D.
AC Characteristics
Figure 17, Program Operations Timing; Figure 19,
Chip/Sector Erase Operations: Deleted tGHWL and
changed OE# waveform to start at high.
Revision D+3 (November 22, 2000)
Global
Erase and Program Operations table; Alternate CE#
Controlled Erase and Program Operations table:
Changed the typical and maximum specifications for
programming time.
Deleted Preliminary status from document. Added
table of contents.
Revision E (July 2, 2001)
Erase and Programming Performance
Added Am29DL161D device to data sheet. Deleted
extended temperature range devices.
In the table, changed the typical and maximum specifi-
cations for programming time. The typical and maxi-
mum chip programming times in both byte and word
modes are reduced.
Sector/Sector Block Protection and Unprotection
Noted that sectors are unprotected in parallel.
Physical Dimensions
SecSi‰ (Secured Silicon) Sector Flash
Memory Region
Replaced figures with more detailed illustrations.
Noted changes for upcoming versions of these de-
vices: reduced SecSi Sector size and deletion of
SecSi Sector erase functionality. Current versions of
these devices remain unaffected.
Revision D+1 (June 21, 2000)
Global
Data sheet designation has changed from “Advance
Information” to “Preliminary.”
Revision E+1 (July 29, 2002)
Deleted references to the 56-pin SSOP and the corre-
sponding 70R speed option.
Global
Added 64-ball Fortified BGA package.
Ordering Information
Command Definitions
Added valid combinations for the Am29DL164D device
in TSOP. Added valid combinations for the
Am29DL162D devices in TSOP and FBGA packages.
Deleted valid combinations for the 80 ns
Am29DL164D device in FBGA package.
Modified caution to state that incorrect command/se-
quences may place device in unknown state, upon
which device must be reset.
Unlock Bypass Command Sequence; Command
Definitions table
Device Bus Operations
Table 3, Sector Addresses for Top Boot Sector De-
vices: In note below table, corrected last device part
number to top boot.
Corrected table and description to indicated that bank
address is not required for unlock bypass reset.
Package Capacitance
Table 7, Autoselect Codes: The SecSi Sector Indicator
Bit values have changed from 80h and 00h to 81h and
01h, respectively.
Added BGA capacitance specifications.
