Note:
The sum of t
and t
must be equal to or greater than t

RPH.
The differences in power-on timing should not present a migration challenge for most applications where the
flash interfaces directly with a Host that requires oscillator and PLL lock prior to initiating the first boot read
access to the flash. In applications which may access the flash within 300 µs of power application, some
circuit modification will be required to accommodate migration to GL-S flash.
To initiate the first read or write cycle after power on, the GL-S requires CE# or OE# to transition from High to
Low no sooner than t
after V
exceeds V
and V
exceeds V
. CE# or OE# must be High at
VCS

least t
= 20 ns prior to CE# or OE# falling edge which initiates the first access.
CEH
CE# is ignored during Warm Reset; however, to initiate the first read or write cycle after warm reset, the GL-S
requires CE# to transition from High to Low no sooner than t
after RESET# transitions from Low to High.
RH
CE# must be high at least t
= 20 ns prior to CE# falling edge, which initiates first access. These were not
CEH
requirements for the GL-P so designs that have CE# fixed low cannot migrate to GL-S without modification to
enable active CE# control.
The GL-S allows V
to ramp concurrently with or after V
with no restriction on time or voltage differential.
IO
CC
During power ramp no input is allowed to exceed V
. The GL-S data sheet provides enhanced direction on
IO
power management and control to design a robust and reliable system.
