Am29DL16xD
February 14, 2003
Revision D (February 22, 2000)
Global
The Am29DL16x family has migrated to a new 0.23
m 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.
Distinctive Characteristics
Under “Performance Characteristics,” the typical ac-
celerated programming time was changed to match
the AC tables.
AC Characteristics
Chip/Sector Erase Operations: Deleted t
GHWL and
changed OE# waveform to start at high.
Erase and Program Operations table; Alternate CE#
Controlled Erase and Program Operations table:
Changed the typical and maximum specifications for
programming time.
Erase and Programming Performance
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.
Physical Dimensions
Replaced figures with more detailed illustrations.
Revision D+1 (June 21, 2000)
Global
Data sheet designation has changed from “Advance
Information” to “Preliminary.”
Deleted references to the 56-pin SSOP and the corre-
sponding 70R speed option.
Ordering Information
Added valid combinations for the Am29DL164D de-
vice in TSOP. Added valid combinations for the
Am29DL162D devices in TSOP and FBGA packages.
D e let ed va lid comb inat ions f o r th e 80 ns
Am29DL164D device in FBGA package.
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.
Table 7, Autoselect Codes: The SecSi Sector Indicator
Bit values have changed from 80h and 00h to 81h and
01h, respectively.
Command Definitions
Table 14, Command Definitions: The SecSi Sector In-
dicator Bit values have changed from 80h and 00h to
81h and 01h, respectively.
AC Characteristics
Read-only Operations table: Changed parameter t
DF to
16 ns for all speed options. Added Note 3.
Revision D+2 (September 4, 2000)
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.
Revision D+3 (November 22, 2000)
Global
Deleted Preliminary status from document. Added
table of contents.
Revision E (July 2, 2001)
Added Am29DL161D device to data sheet. Deleted
extended temperature range devices.
Noted that sectors are unprotected in parallel.
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 E+1 (July 29, 2002)
Global
Added 64-ball Fortified BGA package.
Command Definitions
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
Corrected table and description to indicated that bank
address is not required for unlock bypass reset.
Package Capacitance
Added BGA capacitance specifications.
