1.1

Product Overview

The 5 Volt Boot Block Flash memory family

provides pinout-compatible flash memories at the

2-, 4-, and 8-Mbit densities. The 28F200B5,

28F400B5, and 28F800B5 can be configured to

operate either in 16-bit or 8-bit bus mode, with the

data divided into individually erasable blocks. The

28F004B5 provides 8-bit operation in a compact

package.

NOTE:

1.

As of the publication date of this document, not all 28F200B5 –60 devices meet the 55 ns read specification. Please refer

to the 5 Volt Boot Block Flash Memory Family 28F200B5, 28F004/400B5, 28F800B5 Specification Update to determine

the specific 28F200B5 –T/B60 material that is capable of 55 ns read access times. All other 28F200B5 T/B60 devices are

capable of 60 ns read access times when VCC = 5 V ± 5% and 30 pF load.

2.

Automotive versions of this product are only available as 28F200B5, 28F400B5 and 28F800B5 and are only offered in the

44-Lead PSOP package.
