• Manufacturer Part Number: lh28f160bg-tl
• Description: M-bit Smart Flash Memories
• Manufacturer: Sharp Microelectronics of the Americas

The CUI does not occupy an addressable memory
location. It is written when WE# and CE# are
active. The address and data needed to execute a
command are latched on the rising edge of WE# or
CE# (whichever goes high first). Standard
microprocessor write timings are used. Fig. 10 and
Fig. 11 illustrate WE# and CE# controlled write
operations.

Device operations are selected by writing specific
commands into the CUI. Table 2 defines these
commands.
