A8 = VIH or VIL
A10 - A15 = VIL
Notes:
1. X can be VIL or VIH.
2. Read, output disable, and standby modes require 3.0V ≤VCC ≤3.6V, or 4.5V ≤VCC ≤5.5V.
3. Refer to Programming Characteristics.

Identification Code
4. VH = 12.0 ± 0.5V.
5. Two identifier bytes may be selected. All A8 - A15 inputs are held low (VIL), except A9 which is set to VH and A8 which is
toggled low (VIL) to select the Manufacturer’s Identification byte and high (VIH) to select the Device Code byte.
