3 / 9 page AT27LV020A 3 Block Diagram Absolute Maximum Ratings* *NOTICE: Stresses beyond those listed under “Absolute Maxi- mum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Expo- sure to absolute maximum rating conditions for extended peri- ods may affect device reliability. Note: 1. Minimum voltage is -0.6V dc which may undershoot to -2.0V for pulses of less than 20 ns. Maximum out- put pin voltage is VCC + 0.75V dc which may be exceeded if certain precautions are observed (con- sult application notes) and which may overshoot to +7.0 volts for pulses of less than 20 ns. Operating Modes Notes: 1. X can be VIL or VIH. 2. Read, output disable, and standby modes require, 3.0V ≤ V CC ≤ 3.6V, or 4.5V ≤ VCC ≤ 5.5V. 3. Refer to Programming Characteristics. Programming modes require VCC = 6.5V. 4. VH = 12.0 ± 0.5V. 5. Two identifier bytes may be selected. All Ai inputs are held low (VIL), 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.
