AM29LL800B

8 Megabit (1 M x 8-Bit/512 K x 16-Bit) CMOS 2.2 Volt-only Boot Sector Flash Memory

Advanced Micro Devices 

ADVANCE INFORMATION

REVISION SUMMARY FOR AM29LL800B

Revision A+1

Distinctive Characteristics

Ultra low power consumption bullet: The typical Auto-

matic Sleep Mode and standby mode currents are both

75 nA.

DC Characteristics, CMOS Compatible

The typical current for ICC3, ICC4, and ICC5 is 75 nA.

Revision A+2

Reset Command

Deleted last paragraph in section, which applied to RE-

SET#, not the reset command.

Revision A+3

Figure 2, In-System Sector Protect/Unprotect

Algorithms

In the sector protect algorithm, added a “PLSCNT=1”

box in the path from “Protect another sector?” back to

setting up the next sector address.

DC Characteristics

Changed Note 1 to indicate that OE# is at VIH for the

listed current.

Erase and Program Operations; Alternate CE#

Controlled Erase/Program Operations

Corrected the notes reference for tWHWH1 and tWHWH2.

These parameters are 100% tested. Corrected the

note reference for tVCS. This parameter is not 100%

tested. Removed tOEH parameters from CE# Con-

trolled Erase/Program Operations table for consistency

with other data sheets.

Temporary Sector Unprotect Table

Added note reference for tVIDR. This parameter is not

100% tested.

Figure 23, Temporary Sector Unprotect Timing

Diagram

Changed the high voltage (VID) on the RESET# wave-

form to 10 V.

Figure 24, Sector Protect/Unprotect Timing

Diagram

A valid address is not required for the first write cycle;

only the data 60h.

Erase and Programming Performance

In Note 2, the worst case endurance is now 1 million cy-

cles.
