The 1.8 Volt Intel®Wireless Flash Memory with 3 Volt I/O combines state-of-the-art Intel® Flash technology with
low power SRAM to provide the most versatile and compact memory solution for high performance, low power,
board constraint memory applications.
The 1.8 Volt Intel Wireless Flash Memory with 3 Volt I/O offers a multi-partition, dual-operation flash
architecture that enables the 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
as compared to single partition devices and it allows two processors to interleave code execution because
program and erase operations can now occur as background processes.
The 1.8 Volt Intel Wireless Flash Memory with 3 Volt I/O incorporates a new Enhanced Factory Programming
(EFP) mode to improve 12 V factory programming performance. This new feature helps eliminate manufacturing
bottlenecks associated with programming high density flash devices. Compare the EFP program time of 3.5 µs
per word to the standard factory program time of 8.0 µs per word and save significant factory programming time
for improved factory efficiency.
Additionally, the 1.8 Volt Intel Wireless Flash Memory with 3 Volt I/O includes block lock-down, programmable
WAIT signal polarity and is supported by an array of software tools. All these features make this product a perfect
solution for any demanding memory application.
