Technology
Intel’s 28F016SA 16-Mbit FlashFile™ memory is a revolutionary architecture which is the ideal choice for
designing embedded direct-execute code and mass storage data/file flash memory systems. With innovative
capabilities, low-power, extended temperature operation and high read/program performance, the 28F016SA
enables the design of truly mobile, high-performance communications and computing products.
The 28F016SA is the highest density, highest performance nonvolatile read/program solution for solid-state
storage applications. Its symmetrically-blocked architecture (100% compatible with the 28F008SA 8-Mbit
FlashFile memory), extended cycling, extended temperature operation, flexible VCC, fast program and read
performance and selective block locking provide highly flexible memory components suitable for Resident
Flash Arrays, high-density memory cards and PCMCIA-ATA flash drives. The 28F016SA dual read voltage
enables the design of memory cards which can be interchangeably read/written in 3.3V and 5.0V systems. Its
x8/x16 architecture allows optimization of the memory-to-processor interface. Its high read performance and
flexible block locking enable both storage and execution of operating systems and application software.
Manufactured on Intel’s 0.6 µm ETOX IV process technology, the 28F016SA is the most cost-effective,
highest density monolithic 3.3V FlashFile memory.

1.0 INTRODUCTION
The documentation of the Intel 28F016SA memory
device includes this datasheet, a detailed user’s
manual, and a number of application notes, all of
which are referenced at the end of this datasheet.
The datasheet is intended to give an overview of the
chip feature-set and of the operating AC/DC
specifications. The 16-Mbit Flash Product Family
User’s Manual provides complete descriptions of
the user modes, system interface examples and
detailed descriptions of all principles of operation. It
also contains the full list of software algorithm
flowcharts, and a brief section on compatibility with
Intel 28F008SA.
1.1 Product Overview
The 28F016SA is a high-performance 16-Mbit
(16,777,216 bit) block erasable nonvolatile random
access memory organized as either 1 Mword x
16 or 2 Mbyte x 8. The 28F016SA includes thirty-
two 64-KB (65,536) blocks or thirty-two 32-KW
(32,768) blocks. A chip memory map is shown in
Figure 4.
The implementation of a new architecture, with
many enhanced features, will improve the device
operating characteristics and results in greater
product reliability and ease-of-use.
Among the significant enhancements on the
28F016SA:
3.3V Low Power Capability
Improved Program Performance
Dedicated Block Program/Erase Protection
A 3/5# input pin reconfigures the device internally
for optimized 3.3V or 5.0V read/program operation.
The 28F016SA will be available in a 56-lead,
1.2 mm thick, 14 mm x 20 mm TSOP type I
package or a 56-lead, 1.8 mm thick, 16 mm x
23.7 mm SSOP package. The TSOP form factor
and pinout allow for very high board layout
densities. SSOP packaging provides relaxed lead
spacing dimensions.
A Command User Interface (CUI) serves as the
system interface between the microprocessor or
microcontroller and the internal memory operation.
Internal algorithm automation allows word/byte
programs and block erase operations to be
executed using a two-write command sequence to
the CUI in the same way as the 28F008SA 8-Mbit
FlashFile memory.
A superset of commands have been added to the
basic 28F008SA command-set to achieve higher
program performance and provide additional
capabilities. These new commands and features
include:
Page Buffer Writes to Flash
Command Queueing Capability
Automatic Data Programs during Erase
Software Locking of Memory Blocks
Two-Byte Successive Programs in 8-bit
Systems
Erase All Unlocked Blocks
Writing of memory data is performed in either byte
or word increments typically within 6 µs, a 33%
improvement over the 28F008SA. A block erase
operation erases one of the 32 blocks in typically
0.6 sec, independent of the other blocks, which is a
65% improvement over the 28F008SA.
Each block can be written and erased a minimum of
100,000 cycles. Systems can achieve typically one-
million block erase cycles by providing wear-leveling
algorithms and graceful block retirement. These
techniques have already been employed in many
flash file systems. Additionally, wear leveling of
block erase cycles can be used to minimize the
program/erase performance differences across
blocks.
The 28F016SA incorporates two Page Buffers of
256 bytes (128 words) each to allow page data
writes. This feature can improve a system write
performance by up to 4.8 times over previous flash
memory devices.
All operations are started by a sequence of
command writes to the device. Three Status
Registers (described in detail later) and a RY/BY#
output pin provide information on the progress of
the requested operation.
While the 28F008SA requires an operation to
complete before the next operation can be
requested, the 28F016SA allows queueing of the
next operation while the memory executes the
current operation. This eliminates system overhead
