AT27C512R
Notes:
1. X can be V
IL or VIH.
2. Refer to Programming Characteristics.
3. VH = 12.0 ± 0.5V.
4. Two identifier bytes may be selected. All Ai inputs are held low (V
IL), except A9 which is set to VH and A0 which is toggled
low (VIL) to select the Manufacturer’s Identification byte and high (VIH) to select the Device Code byte.
Note:
1. VCC must be applied simultaneously with or before OE/VPP, and removed simultaneously with or after OE/VPP..
