Technology
Intel’s byte-wide SmartVoltage FlashFile™ memory family renders a variety of density offerings in the same
package. The 4-, 8-, and 16-Mbit byte-wide FlashFile memories provide high-density, low-cost, nonvolatile,
read/write storage solutions for a wide range of applications. Their symmetrically-blocked architecture, flexible
voltage, and extended cycling provide highly flexible components suitable for resident flash arrays, SIMMs,
and memory cards. Enhanced suspend capabilities provide an ideal solution for code or data storage
applications. For secure code storage applications, such as networking, where code is either directly
executed out of flash or downloaded to DRAM, the 4-, 8-, and 16-Mbit FlashFile memories offer three levels
of protection: absolute protection with VPP at GND, selective hardware block locking, or flexible software
block locking. These alternatives give designers ultimate control of their code security needs.
This family of products is manufactured on Intel’s 0.4 µm ETOX™ V process technology. They come in
industry-standard packages: the 40-lead TSOP, ideal for board-constrained applications, and the rugged
44-lead PSOP. Based on the 28F008SA architecture, the byte-wide SmartVoltage FlashFile memory family
enables quick and easy upgrades for designs that demand state-of-the-art technology.

BYTE-WIDE SmartVoltage FlashFile™ MEMORY FAMILY
1.0 INTRODUCTION
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.
1.1 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.
VPPLK has been lowered from 6.5 V to 1.5 V to
support low VPP voltages during block erase,
program, and lock-bit configuration operations.
Designs that switch VPP off during read
operations should transition VPP to GND.
To take advantage of SmartVoltage tech-
nology, allow VPP connection to 3.3 V or 5 V.
For more details see application note AP-625,
28F008SC Compatibility with 28F008SA (order
number 292180).
1.2 Product Overview
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 VCC and block erase and
program operations at 3.3 V, 5 V, and 12 V VPP.
The 12 V VPP option renders the fastest program
and erase performance which will increase your
factory throughput. With the 3.3 V and 5 V VPP
option, VCC and VPP 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 VPP pin gives complete data protection
when VPP VPPLK.

NOTE:
1. Block erase, program, and lock-bit configuration
operation with VCC, 3.0 V are not supported.
Internal VCC and VPP 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.
