Datasheet
Product Features
The Intel
Wireless Flash Memory (W30) device combines state-of-the-art Intel Flash technology to
provide a versatile memory solution for high performance, low power, board constraint memory
applications. The
W30 flash memory device offers a multi-partition, dual-operation flash architecture
that enables the flash device to read from one partition while programming or erasing in another partition.
This Read-While-Write or Read-While-Erase capability makes it possible to achieve higher data
throughput rates compared to single partition devices. Two processors can interleave code execution,
because program and erase operations can now occur as background processes.
The
W30 flash memory device incorporates an Enhanced Factory Programming (EFP) mode to improve
12 V factory programming performance. This feature helps eliminate manufacturing bottlenecks associated
with programming high-density flash memory devices. The EFP program time is 3.5 s per word,
compared to the standard factory program time of 8.0 s per word, so EFP mode saves significant factory
programming time for improved factory efficiency.
The
W30 flash memory device also includes block lock-down and programmable WAIT signal polarity,
and is supported by an array of software tools.
