REVISION SUMMARY FOR Am29F800
Distinctive Characteristics:
High Performance: The fastest speed option available
is now 70 ns.
Enhanced power management for standby mode:
Changed typical standby current to 1 A.
General Description:
Added 70 ns speed option.
Product Selector Guide:
Added -70 column.
Pin Configuration:
Added -70 speed option.
Ordering Information, Standard Products:
The -70 speed option is now listed in the example.
Valid Combinations: Added combinations for the -70
speed option.
Table 7, Command Definitions:
Corrected byte addresses for unlock and command cy-
cles from “2AA” to “AAA”.
In the previous data sheet revision, the addresses for
command definitions were shortened from four hexa-
decimal digits to three. The more accurately represents
the actual address bits required, A10–A0. The remain-
ing upper address bits are don’t cares.
The new address is compatible with the previous four-
digit definition of “AAAA”; the only difference is that the
highest-order hexadecimal digit “A” is now “don’t care”.

In fact, software programs written using the previous
four-digit definitions do not require any changes; they
remain completely compatible with the new three-digit
definitions.
The addresses for the byte-mode read cycles (fourth
cycle) in the autoselect mode are corrected from 01h to
02h for device ID, and from SAX02h to SAX04h for
sector protect verification.
