New Features
The 3 Volt FlashFile memory family maintains basic
compatibility with Intel’s 28F016SA and 28F016SV.
Key enhancements include:
Common Flash Interface (CFI) Support
Scaleable Command Set (SCS) Support
Low Voltage Technology
Enhanced Suspend Capabilities
They share a compatible status register, basic
software commands, and pinout. These similarities
enable a clean migration from the 28F016SA or
28F016SV. When upgrading, it is important to note
the following differences:
Because of new feature and density options,
the devices have different manufacturer and
device identifier codes. This allows for software
optimization.
New software commands.

Product Overview
The 3 Volt FlashFile memory family provides
density upgrades with pinout compatibility for the
16- and 32-Mbit densities. They are high-
performance memories arranged as 1 Mword and
2 Mwords of 16 bits or 2 Mbyte and 4 Mbyte of
8 bits. This data is grouped in thirty-two and sixty-
four 64-Kbyte blocks that can be erased, locked
and unlocked in-system. Figure 1 shows the block
diagram, and Figure 4 illustrates the memory
organization.
This family of products are optimized for fast factory
programming and low power designs. Specifically
designed for 3 V systems, the 28F160S3 and
28F320S3 support read operations at 2.7 V–3.6 V

A Command User Interface (CUI) serves as the
interface between the system processor and
internal device operation. 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.
A block erase operation erases one of the device’s

commercial temperature range (0 °C to +70 °C) and
10,000 times in the extended temperature range
(–40 °C to +85 °C). Block erase suspend mode
allows system software to suspend block erase to
read or write data from any other block.
Data is programmed in byte, word or page
increments. Program suspend mode enables the
