General Description

Third paragraph: Added 45 ns to access times.

Product Selector Guide

Added the -45 speed option for VCC = 5.0 V ± 5% and

the -55 speed option for VCC = 5.0 V ± 10%.

Ordering Information

Added “Special Designation” to “Optional Processing”

heading; added “0” for 55 ns 10% VCC, deleted burn-in.

Burn-in is available by contacting an AMD representative.

Added -55 ± 10% and -45 speed options to the list of

valid combinations. Added extended temperature

ratings to -55 ±5% valid combinations.

Table 1, Device Bus Operations

Changed the BYTE#=VIL input for DQ8–DQ15 during

temporary sector unprotect to “don’t care” (X).

Figure 6. Maximum Negative Undershoot

Waveform

Corrected figure title.

Table 7, Test Specifications

Test load capacitance: Removed 55 ns speed option

from and added -45 speed option to the 30 pF.

DC Characteristics
