4 / 9 page 4 0015O–EPROM–12/07 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.. 6. Operating Modes Mode/Pin CE OE/V PP Ai Outputs Read V IL V IL Ai D OUT Output Disable VIL VIH X(1) High Z Standby V IH X(1) X High Z Rapid Program(2) VIL VPP Ai DIN PGM Inhibit VIH VPP X(1) High Z Product Identification(4) VIL VIL A9 =V H (3) A0 = VIH or VIL A1 - A15 = VIL Identification Code 7.
