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.

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.
