BYTE-WIDE SmartVoltage FlashFile™ MEMORY FAMILY
INTRODUCTION

Product Overview
This datasheet contains 4-, 8-, and 16-Mbit
SmartVoltage FlashFile memory specifications.
Section 1.0 provides a flash memory overview.
Sections 2.0, through 5.0 describe the memory
organization and functionality. Section 6.0 covers
electrical specifications for commercial and
extended temperature product offerings. Section
7.0 contains ordering information. Finally, the byte-
wide SmartVoltage FlashFile memory family
documentation also includes application notes and
design tools which are referenced in Section 8.0.
The byte-wide SmartVoltage FlashFile memory
family provides density upgrades with pinout
compatibility for the 4-, 8-, and 16-Mbit densities.
The 28F004SC, 28F008SC, and 28F016SC are
high-performance
memories
arranged
as
512 Kbyte, 1 Mbyte, and 2 Mbyte of 8 bits. This
data is grouped in eight, sixteen, and thirty-two
64-Kbyte blocks which are individually erasable,
lockable, and unlockable in-system. Figure 4
illustrates the memory organization.
SmartVoltage technology enables fast factory
programming and low-power designs. These
components support read operations at 2.7 V (read-
only), 3.3 V, and 5 V V
CC
and block erase and
program operations at 3.3 V, 5 V, and 12 V V
PP
.
The 12 V V
PP
option renders the fastest program
and erase performance which will increase your
factory throughput. With the 3.3 V and 5 V V
PP
option, V
CC
and V
PP
can be tied together for a
simple and voltage flexible design. This voltage
flexibility is key for removable media that need to
operate in a 3 V to 5 V system. In addition, the
dedicated V
PP
pin gives complete data protection
when V
PP
≤
V
PPLK
.

New Features
The byte-wide SmartVoltage FlashFile memory
family maintains backwards-compatibility with
Intel’s
28F008SA
and
28F008SA-L.
Key
enhancements include:
•
•
•
SmartVoltage Technology
Enhanced Suspend Capabilities
In-System Block Locking
They share a compatible status register, software
commands, and pinouts. These similarities enable
a clean upgrade from the 28F008SA and
28F008SA-L to byte-wide SmartVoltage FlashFile
products. When upgrading, it is important to note
the following differences:
•
Because of new feature and density options,
the devices have different device identifier
codes. This allows for software optimization.
V
PPLK
has been lowered from 6.5 V to 1.5 V to
support low V
PP
voltages during block erase,
program, and lock-bit configuration operations.
Designs that switch V
PP
off during read
operations should transition V
PP
to GND.
To take advantage of SmartVoltage tech-
nology, allow V
PP
connection to 3.3 V or 5 V.
•
NOTE:
1. Block erase, program, and lock-bit configuration
operation with V
CC
, 3.0 V are not supported.
•
Internal V
CC
and V
PP
detection circuitry
automatically configures the device for optimum
performance.
A Command User Interface (CUI) serves as the
interface between the system processor and
internal operation of the device. A valid command
sequence written to the CUI initiates device
automation. An internal Write State Machine (WSM)
automatically executes the algorithms and timings
necessary for block erase, program, and lock-bit
configuration operations.
