SMART 5 BOOT BLOCK MEMORY FAMILY
•
•
A delay is required if the part is reset during an
in-progress program or erase operation.
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.
INTRODUCTION
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.

Product Overview
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
CC
read voltage.
The following differences distinguish the Smart 5
boot block products from their predecessors:
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.
