3 / 13 page 3 0015P–EPROM–10/11 Atmel AT27C512R 4. Absolute maximum ratings* Note: 1. Minimum voltage is -0.6V DC, which may undershoot to -2.0V for pulses of less than 20ns. Maximum output pin voltage is V CC + 0.75V DC, which may overshoot to +7.0V for pulses of less than 20ns. 5. DC and AC characteristics Table 5-1. Operating modes Notes: 1. X can be V IL or VIH. 2. Refer to programming characteristics. 3. V H = 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 tog- gled low (V IL) to select the manufacturer’s identification byte and high (VIH) to select the device code byte.
