.DThe 1.8 Volt Intel® Wireless Flash memory with flexible multi-partition dual-operation provides high-
performance asynchronous and synchronous burst reads. It is an ideal memory for low-voltage burst CPUs.
wCombining high read performance with flash memory’s intrinsic non-volatility, 1.8 Volt Intel Wireless Flash
memory eliminates the traditional system-performance paradigm of shadowing redundant code memory from
slow nonvolatile storage to faster execution memory. It reduces the total memory requirement that increases
wreliability and reduces overall system power consumption and cost.
mThe 1.8 Volt Intel Wireless Flash memory’s flexible multi-partition architecture allows programming or erasing to
woccur in one partition while reading from another partition. This allows for higher data write throughput
ocompared to single partition architectures. The dual-operation architecture also allows two processors to
.cinterleave code operations while program and erase operations take place in the background. The designer can
also choose the size of the code and data partitions via the flexible multi-partition architecture.
t4UThe 1.8 Volt Intel Wireless Flash memory is manufactured on Intel’s 0.18 µm ETOX™ VII process technology. It
is available in µBGA and VF BGA packages which are ideal for board-constrained applications.
