sector protect verify. Added note 3 to explain sector
protect codes. In Note 8, changed A13 to A11, added
“unless otherwise noted”; is now new Note 6.
DATA SHEET REVISION SUMMARY FOR
AM29LV008
Distinctive Characteristics:
RESET: Hardware Reset Pin:
Rearranged bullets. Renamed “2.7 to 3.6 volt, ex-
tended voltage range...” to “Single power supply opera-
tion.” Under “Single power supply operation” and “High
performance” bullets, defined standard and extended
voltage ranges and added 90 ns speed option. Com-
bined “Advanced power management” and “Low cur-
rent consumption” bullets into new “Ultra low power
consumption” bullet. Under that bullet, revised the typ-
ical standby and automatic sleep mode current specifi-
cations from 1 µA to 200 nA; revised read current
specification from 10 mA to 2 mA/MHz. Combined
“Sector protection” and “Flexible sector architecture”
bullets. Under flexible sector architecture bullet, added
temporary sector unprotect feature description. Com-
bined Embedded Program and Embedded Erase bul-
lets 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.
Fourth paragraph: Revised standby mode specification
to 200 nA.
Operating Ranges:
V
Supply Voltages: Added 3.0 to 3.6 V voltage range
CC
and -90R speed option.
DC Characteristics:
CMOS Compatible: Changed I
from 30 mA maxi-
CC1
mum at 6 MHz to 16 mA maximum at 5 MHz and 4 mA
maximum at 1 MHz. Changed I from 35 mA to 30
CC2
mA maximum. In the V specification, changed the
OL
I
test condition from 5.8 to 4.0 mA. In Note 1,
OL
changed 6 MHz to 5 MHz. In Note 3, changed address
stable time from 300 ns to 200 ns; changed typical au-
tomatic sleep mode current from 1 µA to 200 nA.
Figure 8A, I Current vs.Time, and Figure 8B, I
CC
CC
vs. Frequency:
Figure 8A illustrates current draw during the Automatic
Sleep Mode after the addresses are stable. Figure 8B
shows how frequency affects the current draw curves
for both voltage ranges.
General Description:
Added text on new speed option and voltage range to
the second paragraph.
Product Selector Guide:
AC Characteristics:
Added -90R voltage range and speed option.
Read Only Operations Characteristics: Added -90R
column.
Pin Configuration:
Added new voltage range for -90R to V specification.
Test Conditions, Figure 9:
CC
Ordering Information, Standard Products:
Added 90 ns speed to C note.
L
The -90R speed option is now listed in the example.
Revised “Speed Option” section to indicate both volt-
age ranges.
AC Characteristics:
Write/Erase/Program Operations: Added the -90R col-
umn.
Valid Combinations: Added -90R speed option and
voltage range.
Figure 13, AC Waveforms for Program Operations:
Changed 5555H to 555H in addresses waveform to
match command definitions (Table 5).
Automatic Sleep Mode:
Revised addresses stable time to 200 ns and current
draw to 200 nA.
Figure 14, AC Waveforms for Chip/Sector Erase
Operations:
Table 5, Command Definitions:
Changed 5555H to 555H in addresses waveform to
match command definitions (Table 5).
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 new Notes
4 and 5. Expanded autoselect section to show each
function separately: manufacturer ID, device ID, and
Figure 19,Temporary Sector Unprotect Diagram:
Corrected callouts on RESET waveform to “0 V or 3 V”.
AC Characteristics:
Alternate CE Controlled Writes: Added the -90R col-
umn. Changed t from 45 to 50 ns for -100, from 50 to
AH
65 ns for -150. Changed t from 50 to 65 ns for -150.
DS
Changed t from 45 to 50 ns for -100, from 50 to 65
CP
ns for -150. Changed t
from 20 to 30 ns for -100, -
CPH
120; from 20 to 35 ns for -150.
