It is important to let you know that the E28F200B5T80 and the rest of the Intel(R) 5 Volt Boot BlockFlash Memories have been ended of life since the 8 / 1 / 2001, also the mentioned site is related to our obsolete products dealer as you can confirm at the Intel® Authorized Distributors of Embedded Products page.
By the way, all the Flash Memories have been acquired by Micron Technology, Inc. as you may confirm as a reference at the following websites:
Due to this fact, any Flash Memory questions should be addressed to Micron.
On the other hand, the BL440ZX questions should be addressed to the Forum: Desktop Boards |Intel Communities.
