Identification Code
Notes: 1. X can be VIL or VIH.
2. Non-Linear and Linear Access Cycles, and standby modes require, 3.0V VCC 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 words 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 word and high (VIH) to select the Device Code word.

Notes: 1. The Input Timing Reference is 0.8V for VIL and 2.0V for VIH.
2. tCS and tDFP are characteristics of the device but must accompanied by the programmer.
3. When programming the AT27LV1026 a 0.1 µF capacitor is required across VPP and ground to suppress spurious voltage
transients.
