SMART 5 BOOT BLOCK MEMORY FAMILY

1.0 INTRODUCTION

•

A delay is required if the part is reset during an

in-progress program or erase operation.

This datasheet contains specifications for 2-, 4-,

and 8-Mbit Smart 5 boot block flash memories.

Section 1.0 provides a feature overview. Sections

2.0, 3.0, and 4.0 describe the product and

functionality. Section 5.0 details the electrical and

timing specifications for both commercial and

extended temperature operation. Finally, Sections

6.0 and 7.0 provide ordering and reference

information.

On the fly word-byte mode switching is no

longer supported. Word-byte mode must be

configured at power-up and remain stable

during operation.

•

Write operations are no longer specified as

WE#- or CE#-controlled in favor of a simpler

“unified” write method, which is compatible

with either of the old methods.

Product Overview

The Smart 5 boot block 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.

The Smart 5 boot block flash memory family offers

identical features with the BV/CV/BE/CE

SmartVoltage products, except the Smart 5 boot

block -B5 parts only support 5 V V_CCread voltage.

The following differences distinguish the Smart 5

boot block products from their predecessors:
