POWER SUPPLY
Power Up
The memory Command Interface is reset on power
up to Read Array. Either E or W must be tied to VIH
during Power Up to allow maximum security and
the possibility to write a command on the first rising
edge of E and W. Any write cycle initiation is
blocked when Vcc is below VLKO.
Supply Rails
Normal precautions must be taken for supply volt-
age decoupling; each device in a system should
have the VCC rail decoupled with a 0.1µF capacitor
close to the VCC and VSS pins. The PCB trace
widths should be sufficient to carry the VCC pro-
gram and erase currents required.
