are valid. Likewise, the device has a wake time

(tPHWL) from RP#-high until writes to the CUI are

recognized. With RP# at GND, the WSM is reset

and the status register is cleared.

The Intel StrataFlash memory devices are

available in several package types. The 64-Mbit is

available in 56-lead SSOP (Shrink Small Outline

Package) and µBGA* package (micro Ball Grid

Array). The 32-Mbit is available in 56-lead TSOP

(Thin Small Outline Package), 56-lead SSOP, and

56-bump µBGA packages. Figures 2, 3, and 4

show the pinouts.
