Identification Code
A10 - A15 = V IL
Notes:
1. X can be V IL or V IH.
2. Read, output disable, and standby modes require 3.0V ≤ V CC ≤ 3.6V, or 4.5V ≤ V CC ≤ 5.5V.
3. Refer to Programming Characteristics.
4. V H = 12.0 ± 0.5V.
5. Two identifier bytes may be selected. All A8 - A15 inputs are held low (V IL ), except A9 which is set to V H and A8 which is
toggled low (V IL ) to select the Manufacturer’s Identification byte and high (V IH ) to select the Device Code byte.
