PRELIMINARY

REVISION SUMMARY FOR AM29F002/AM29F002N

Revision C

Global

Made formatting and layout consistent with other data

sheets. Used updated common tables and diagrams.

Combined Am29F002 and Am29F002N into a single

data sheet.

Revision C+1

Figure 17, Alternate CE# Controlled Write

Operations Timings

Removed the RY/BY# waverform and tBUSY parameter.

The RY/BY# pin is not available on this device.

Revision C+2

Block Diagram

Corrected diagram by adding paths from the timer to

the PGM and Erase Voltage Generators.

Table 3, Bottom Boot Block Sector Addresses

Corrected adddress bit A15 for sector SA2 to “0.”

Table 5, Command Definitions

Deleted the lower row of addresses in the Sector Pro-

tect Verify command definitions.

In the legend, corrected the definition for SA to indicate

that address bits A17–A13 uniquely select a sector.

Deleted Note 4.

DC Characteristics

Added Note 4 reference to ILIT. Corrected maximum

currents for ICC1 and ICC2, typical currents for ICC3 and

ICC4, test conditions for ICC4 and VOL.

In TTL/NMOS table, deleted Note 5.

In CMOS table, corrected IOH current for VOH.

AC Characteristics

Read Operations: Corrected tDF specifications for -55

speed option.

Erase/Program Operations: Corrected the notes refer-

ence for tWHWH1 and tWHWH2. These parameters are

100% tested. Corrected the note reference for tVCS.

This parameter is not 100% tested. Removed -150

specifications. Corrected tDS and tWP for -55 speed op-

tion, tAH for -90 speed option.

Alternate CE# Controlled Erase/Program Operations:

Corrected the notes reference for tWHWH1 and tWHWH2.

These parameters are 100% tested. This parameter is

not 100% tested. Removed -150 specifications. Cor-

rected tDS and tCP for -55 speed option.

Temporary Sector Unprotect Table

Added note reference for tVIDR. This parameter is not

100% tested.
