Preface
Preface
This document is an update to the specifications contained in the Affected Documents/Related
Documents table below. This document is a compilation of device and documentation errata,
specification clarifications and changes. It is intended for hardware system manufacturers and
software developers of applications, operating systems, or tools.
Information types defined in Nomenclature are consolidated into the specification update and are
no longer published in other documents.
This document may also contain information that was not previously published.

Nomenclature
Errata are design defects or errors. These may cause the behavior of the 28F800C3, 28F160C3,
28F320C3, 28F640C3 to deviate from published specifications. Hardware and software designed
to be used with any given stepping must assume that all errata documented for that stepping are
present on all devices.
Specification Changes are modifications to the current published specifications. These changes
will be incorporated in any new release of the specification.
Specification Clarifications describe a specification in greater detail or further highlight a
specification’s impact to a complex design situation. These clarifications will be incorporated in
any new release of the specification.
Documentation Changes include typos, errors, or omissions from the current published
specifications. These will be incorporated in any new release of the specification.
Note: Errata remain in the specification update throughout the product’s life cycle, or until a particular
stepping is no longer commercially available. Under these circumstances, errata removed from the
specification update are archived and available upon request. Specification changes, specification
clarifications, and documentation changes are removed from the specification update when the
appropriate changes are made to the appropriate product specification or user documentation
(datasheets, manuals, etc.).

28F320C3xC Maximum ICCE when Vpp=12V
Problem:
When VPP=12V, ICCE Max on 28F320C3xC devices on the 0.18µm deviates from the published
specification and increases from 15mA to 25mA. The following is the revised specification for
these products.

Implication:
Status:
The increased current requirements may result in increased power drawn from the power supply
during limited 12 V production programming. 3 V programming is unaffected.
32-Mb devices on the 0.18mm process are affected.
2.
28F320C3xC Reset Failure
Problem:
The 0.18µm 28F320C3xC devices can unintentionally reset under certain conditions where VPP
toggles.
Implication:
When the reset occurs, any command being executed is interrupted and the flash switches to read
array mode.
Workaround: There are four workarounds for this erratum:
1) Tie VPP to VCC
;
2) If the third and forth digits on the top side FPO mark (third line) is equal or greater than “23”,
then VCC may be set from 2.7v to 3.3v. VCC must not exceed 3.3v
3) Set VPP to a static high or static low level as shown here; and
Hold VPP Static

28F640C3xC Maximum ICCS and ICCD Change
Problem:
On the 0.18µm 28F640C3xC devices, the maximum ICCS and ICCD deviates from the published
specification and increases from 15 µA to 20 µA. The following table shows the revised ICCS and

Implication:
The increased current requirements may result in a nominal increase in power drawn from the
power supply.
Workaround: None
Status: This erratum affects all 0.18µm 28F640C3xC devices. Root cause has been identified and this
erratum may be fixed in a future stepping of the product.

4.
28F160C3xC Erase Resume Issue
Problem:
On the 0.18µm 28F160C3xC devices, a design anomaly was discovered. During an Erase-Suspend
operation, if the Program (40H/10H) sequence is executed, under limited conditions the proceeding
Erase Resume command (D0H) may not actually resume the device. No customers have reported
failures in product applications. Customers who use any version of FDI (Intel Flash Data
Integrator) software will not see this issue. If the Read Array command is issued prior to the Erase
Resume command, users will not see the issue (typical in XIP applications).
Implication:
The Resume Command (D0H) may be ignored by the device and will not correctly resume. The
device will appear to remain in suspend (via status register). After a reset of the flash device the
status register will clear. This failure has been recreated in a lab environment only.
Workaround: There are 2 workarounds for this erratum.
1. If FDI (Intel Flash Data Integrator) software is used, users will not see the issue.
2. During an Erase-Suspend (B0H), user must issue any of the following commands after issuing
the Program (40H/10H) and data sequence but before issuing the Erase-Resume (D0H)
command.

5.
28F160C3xC and 28F640C3xC Lock/Unlock/Lock-Down Operation
Problem:
On the 16Mb and 64Mb 0.18µm devices, if CE# is deasserted after any block lock operation and
before the next write sequence, the part may perform the same operation on additional blocks. (See
waveform below.)
CE#
0x60
0x2F
WE#
Implication:
When CE# is deasserted after performing a block lock operation to a specific block and prior to the
next write sequence, other blocks may perform the same operation.
Workaround: Depending on software implementation, systems may already be effectively managing this
erratum. There is currently a workaround for this erratum:
Immediately after performing a block lock, unlock, or lock-down operation, perform a valid write
sequence before chip enable (CE#) is deasserted.
For example, one possible solution is shown below:
1) Assert CE# and toggle WE# to write the block lock setup command (0x60).
2) Toggle WE# a second time to write the confirm command (lock = 0x01; unlock = 0xD0; lock-
down = 0x2F).
3) Toggle WE# a third time (ex: 0xFF- Read Array) before CE# is deasserted. (See waveform
below.) Any other valid write sequence will also work (i.e., 0x90 - Read Configuration, 0x40 -
Program, 0x20 - Erase).

CFI templates that support the Advanced+ Boot Block features will recognize block locking and

will be corrected on future steppings.

Issue:

that is in the Lockdown or Locked-Lockdown state. WP# must be held valid for all three bus

Customers may need to modify their software. Note: If the Locking Operations Flowchart (Figure

Status Register command, software modifications are not necessary. Future steppings will require
WP# valid only through the Write Lock, Unlock, or Lockdown commands.

NOTE: 1. VCC and VCCQ must share the same the same supply when they are in the VCC1 range.
The maximum VCC has changed on the 0.25µm 32-Mb devices. The maximum VCC specification
has not changed on the 16-Mb, 8-Mb. This may become an issue if the system voltage regulator
used has a VCC range tolerance that is outside the new specification, which may cause the device to
operate in a condition which is outside the specifications of the current datasheet.
