PRELIMINARY

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

µA 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 VCC 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.

Figure 6, Timing Diagram for Byte Mode

Conﬁguration:

Moved end of tFLQZ period from within the A-1 data ﬂow

to the start of A-1 data ﬂow.

Operating Ranges:

VCC Supply Voltages: Expanded into two voltage

ranges; added -90R speed option.

DC Characteristics:

CMOS Compatible: Changed ICC1 from 30 mA maxi-

mum at 6 MHz to 16 mA maximum at 5 MHz and 4 mA

maximum at 1 MHz. Changed ICC2 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

µA

to 200 nA.

Figure 13A, ICC Current vs. Time, and Figure 13B,

ICC 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.

AC Characteristics:

Read Only Operations Characteristics: Added -90R

column.

Test Conditions, Figure 13:

Added 90 ns speed to CL note.

AC Characteristics:

Write/Erase/Program Operations: Added the -90R col-

umn. Corrected tWAX to tWLAX.
