Notice On Data Sheet Designations
Spansion Inc. issues data sheets with Advance Information or Preliminary designations to advise readers of
product information or intended specifications throughout the product life cycle, including development,
qualification, initial production, and full production. In all cases, however, readers are encouraged to verify
that they have the latest information before finalizing their design. The following descriptions of Spansion data
sheet designations are presented here to highlight their presence and definitions.
Advance Information
The Advance Information designation indicates that Spansion Inc. is developing one or more specific
products, but has not committed any design to production. Information presented in a document with this
designation is likely to change, and in some cases, development on the product may discontinue. Spansion
Inc. therefore places the following conditions upon Advance Information content:
“This document contains information on one or more products under development at Spansion Inc.
The information is intended to help you evaluate this product. Do not design in this product without
contacting the factory. Spansion Inc. reserves the right to change or discontinue work on this proposed
product without notice.”
Preliminary
The Preliminary designation indicates that the product development has progressed such that a commitment

Data
Sheet
(Pre limin ar y)
General Description
The S29CD-G Flash Family is a burst mode, Dual Boot, Simultaneous Read/Write family of Flash Memory
with VersatileI/O™ manufactured on 170 nm Process Technology.
The S29CD032G is a 32 Megabit, 2.6 Volt-only (2.50 V - 2.75 V) single power supply burst mode flash
memory device that can be configured for 1,048,576 double words.
The S29CD016G is a 16 Megabit, 2.6 Volt-only (2.50 V - 2.75 V) single power supply burst mode flash
memory device that can be configured for 524,288 double words.
To eliminate bus contention, each device has separate chip enable (CE#), write enable (WE#) and output
enable (OE#) controls. Additional control inputs are required for synchronous burst operations: Load Burst
Address Valid (ADV#), and Clock (CLK).
Each device requires only a single 2.6 Volt-only (2.50 V – 2.75 V) for both read and write functions. A 12.0-
volt V
PP
is not required for program or erase operations, although an acceleration pin is available if faster
programming performance is required.
The device is entirely command set compatible with the JEDEC single-power-supply Flash standard. The
software command set is compatible with the command sets of the 5 V Am29F or MBM29F and 3 V Am29LV
or MBM29LV Flash families. Commands are written to the command register using standard microprocessor
write timing. Register contents serve as inputs to an internal state-machine that controls the erase and
programming circuitry. Write cycles also internally latch addresses and data needed for the programming and
erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices.
The
Unlock Bypass
mode facilitates faster programming times by requiring only two write cycles to program
data instead of four.
The
Simultaneous Read/Write architecture
provides simultaneous operation by dividing the memory space
into two banks. The device can begin programming or erasing in one bank, and then simultaneously read
from the other bank, with zero latency. This releases the system from waiting for the completion of program or
erase operations. See
Simultaneous Read/Write Operations Overview
on page 23.
The device provides a 256-byte
Secured Silicon Sector
that contains Electronic Marking Information for
easy device traceability.
In addition, the device features several levels of sector protection, which can disable both the program and
erase operations in certain sectors or sector groups:
Persistent Sector Protection
is a command sector
protection method that replaces the old 12 V controlled protection method;
Password Sector Protection
is a
highly sophisticated protection method that requires a password before changes to certain sectors or sector
groups are permitted;
WP# Hardware Protection
prevents program or erase in the two outermost 8 Kbytes
sectors of the larger bank.
The device defaults to the Persistent Sector Protection mode. The customer must then choose if the
Standard or Password Protection method is most desirable. The WP# Hardware Protection feature is always
available, independent of the other protection method chosen.
The
VersatileI/O™ (V
CCQ
)
feature allows the output voltage generated on the device to be determined based
on the V
IO
level. This feature allows this device to operate in the 1.8 V I/O environment, driving and receiving
signals to and from other 1.8 V devices on the same bus.
The host system can detect whether a program or erase operation is complete by observing the RY/BY# pin,
by reading the DQ7 (Data# Polling), or DQ6 (toggle)
status bits.
After a program or erase cycle is completed,
the device is ready to read array data or accept another command.
The
sector erase architecture
allows memory sectors to be erased and reprogrammed without affecting the
data contents of other sectors. The device is fully erased when shipped from the factory.
Hardware data protection
measures include a low V
CC
detector that automatically inhibits write operations
during power transitions. The
password and software sector protection
feature disables both program and
erase operations in any combination of sectors of memory. This can be achieved in-system at V
CC
level.
The
Program/Erase Suspend/Erase Resume
feature enables the user to put erase on hold for any period of
time to read data from, or program data to, any sector that is not selected for erasure. True background erase
can thus be achieved.
The
hardware RESET# pin
terminates any operation in progress and resets the internal state machine to
reading array data.

The device offers two power-saving features. When addresses are stable for a specified amount of time, the
device enters the
automatic sleep mode.
The system can also place the device into the
standby mode.
Power consumption is greatly reduced in both these modes.
AMD’s Flash technology combines years of Flash memory manufacturing experience to produce the highest
levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a sector
simultaneously via Fowler-Nordheim tunnelling. The data is programmed using hot electron injection.
