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 t
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.
