REVISION SUMMARY FOR AM29LV800
Distinctive Characteristics:
Rearranged bullets. Renamed “Extended voltage
range...” bullet to “Single power supply operation.”
Under “Single power supply operation” and “High per-
formance” bullets, defined standard and extended volt-
age ranges and added 90 ns speed option. Combined
“Advanced power management” and “Low current con-
sumption” bullets into new “Ultra low power consump-
tion” bullet. Under that bullet, revised the typical
standby and automatic sleep mode current specifica-
tions from 1
μ
A to 200 nA; revised read current specifi-
cation from 10 mA to 2 mA/MHz. Combined “Sector
protection” and “Flexible sector architecture” bullets.
Under flexible sector architecture bullet, added tempo-
rary sector unprotect feature description. Combined
Embedded Program and Embedded Erase bullets
under new “Embedded Algorithms” bullet; removed
designations. Clarified descriptions of sector protec-
tion, erase suspend/resume, hardware reset pin,
ready/busy pin, and data polling and toggle bits.
General Description:
Added text on -90R speed option and voltage range to
the second paragraph.
Product Selector Guide:
Added -90R voltage range and speed option.
Connection Diagrams
Corrected pinouts on pins 13 and 14 for the standard
TSOP drawing. (Revision C)
Corrected pinouts on pins 33 and 32 for the reverse
TSOP drawing. (Revision C)
Corrected pinouts for pins 13, 14, 17, and 18 on stan-
dard TSOP package. (Revision D)
Pin Configuration:
Added new voltage range to V
CC
specification.
Ordering Information, Standard Products:
The -90R speed option is now listed in the example.
Revised “Speed Option” section to indicate both volt-
age ranges.
Valid Combinations:Added -90R speed option and
voltage range.
Automatic Sleep Mode:
Revised addresses stable time to 200 ns and typical
current draw to 200 nA.
Autoselect:
Fourth paragraph, last sentence: Corrected to “...DQ9
and DQ13 are equal to ‘1’...”
Table 4, Sector Address Table:
Corrected SA12, x8 starting address from D0000 to
C0000.
Table 6, Command Definitions:
Grouped address designators PA, PD, RA, RD, and SA
under the legend heading. Modified SA definition to ac-
commodate the sector protect verify command. Since
unlock addresses only require address bits A0–A10 to
be valid, the number of hexadecimal digits in the unlock
addresses were changed from four to three. The re-
maining upper address bits are don’t care. Removed
“H” designation from hexadecimal values in table and
replaced with new Note 1. Revised Notes 5 and 6 to in-
dicate when commands are valid; are now Notes 4 and
5. Expanded autoselect section to show each function
separately: manufacturer ID, device ID, and sector pro-
tect verify. Added Note 3 to explain sector protect
codes. Deleted Note 7. Added Note 6 to indicate which
addresses are don’t care. Corrected unlock and com-
mand addresses for byte mode from “2AA” to “AAA”.
Corrected byte-mode read cycle (fourth cycle) ad-
dresses from 01h to 02h for device ID, and from SAX02
to SAX04 for sector protect verification.
RESET: Hardware Reset Pin:
Fourth paragraph: Revised standby mode specification
to 200 nA.

period from within the A-1 data flow
to the start of A-1 data flow.
Operating Ranges:
V
CC
Supply Voltages:Expanded into two voltage
ranges; added -90R speed option.
DC Characteristics:
CMOS Compatible:Changed I
CC1
from 30 mA maxi-
mum at 6 MHz to 16 mA maximum at 5 MHz and 4 mA
maximum at 1 MHz. Changed I
CC2
from 35 mA to 30
mA maximum. In Note 1, changed 6 MHz to 5 MHz. In
Note 3, changed address stable time from 300 ns to
200 ns; changed typical sleep mode current from 1
μ
A
to 200 nA.

Sleep Mode after the addresses are stable. Figure 8B
shows how frequency affects the current draw curves
for both voltage ranges.
AC Characteristics:
Read Only Operations Characteristics:Added -90R
