Notes: 1. X can be VIL or VIH.
2. Refer to Programming Characteristics.

A0 = VIH or VIL
VCC
Identification Code
A1 - A14 = VIL
3. VH = 12.0 ± 0.5V.
4. 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.
5. Standby VCC current (ISB) is specified with VPP = VCC. VCC > VPP will cause a slight increase in ISB.

1. VCC must be applied simultaneously with or before VPP, and removed simultaneously with or after VPP.
2. VPP may be connected directly to VCC, except during programming. The supply current would then be the sum of ICC and IPP.
