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.

Affected Documents/Related Documents

Nomenclature

Errata are design defects or errors. These may cause the behavior of the 28F004/400B3, 28F008/

800B3, 28F016/160B3, 28F320B3, 28F640B3 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.).

10 Specification Update

Errata

1. Block Locking during Write Operations If CE# Is Toggled High

Problem: In normal operation, WP# = VIL locks the upper two (or lower two, in the case of a bottom boot

device) parameter blocks. If a program or erase command is issued to a locked block, the WSM

sets the program or erase status bit and the block lock status bit to “1” and prevents the program or

erase operation to the locked block.

However, initial samples of the 28F160B3 flash memory device ignore the WP# pin if CE# is

toggled high during the second cycle of a program or erase operation. Any program and/or erase

commands issued to locked blocks may change memory contents even if WP# = VIL (assuming

VPP >V

PPLK).

Implication: This erratum causes the lockable blocks to be unlocked regardless of the state of WP# when CE# is

toggled high during the write cycle(s).

Workaround: Applications using A-0 material should hold CE# low and toggle WE# to latch command, address,

and data during a program or erase operation.

Only 28F160B3 A-0 stepping (0.4 µm material) is affected by this erratum. This erratum has been

fixedintheA-1stepping.RefertoSummary Table of Changes to determine the affected

stepping(s).

Errata

2. Invalid Read Durations for CE# High Pulse Width

Problem: During consecutive read operations, CE# may be left low or toggled as desired. If CE# is toggled

high (see diagram below) for 4 µs–11 µs between read operations, subsequent reads will return

incorrect data.

Implication: If CE# is not toggled between consecutive reads, there is no impact. Any application that toggles

CE# between read operations will be affected if the CE# high pulse width is within the nonfunc-

tional range, i.e., 4 µs ≤ tEHEL ≤11 µs.

Workaround: Either of the following actions will prevent this erratum:

1. Do not toggle CE# between consecutive read operations

2. Insure tEHEL is less than 4 ms or greater than 11 µs

Status: Only 28F160B3 A-0 stepping (0.4 µm material) is affected by this erratum. This erratum has been

fixed in the A-1 stepping. Refer to Summary Table of Changes to determine the affected

stepping(s).

3. Temperature Effect on VCC Ramp

Problem: The 28F160B3 flash memory operates from 2.7 V–3.6 V across the full extended temperature

range (–40 °C to +85 °C). For a limited number of 28F160B3 engineering samples, when ramping

VCC to below 3.0 V and below +10 °C (–40 °C to +10 °C), the device is not guaranteed to respond

to read, program, and erase operations (see diagram below). If VCC ramps to a value between 3.0 V

and 3.6 V, the device functions normally across the entire extended temperature range.

Implication: If VCC is ramped to [and maintained at] a level below 3 V between –40 °C and +10 °C, the device

may not function properly.

Errata

Workaround: Either of the following actions will prevent this erratum:

1. Ramp VCC above 3.0 V in order to trip the VCC detector; once the detector has “tripped,” the

voltage may be lowered below 3.0 V for normal operation

2. Only ramp VCC at temperatures above +10 °C.

Status: Only engineering samples of 28F160B3 A-0 stepping (0.4 µm material) from lot 7705998FOB and

7705999FOB [backside mark] are affected. This erratum affects all A-0 µBGA* package

engineering samples. Only A-0 TSOP samples with a printed backside mark are affected. If the

TSOP package has no backside mark then it is not affected. This erratum has been fixed in the

A-1 stepping.

4. Program and Erase Failure When VPP =12VandV

CCQ = 1.65 V - 2.5 V

Problem: During production programming (VPP = 12 V) with VCCQ between 1.65 V and 2.5 V, the device

will fail to program or erase.

Implication: Customers should not implement 12 V production programming with VCCQ between 1.65 V and

2.5 V. This may be corrected on future steppings.

Status: Refer to the Summary Tables of Changes to determine the affected stepping(s).

5. Maximum ICCD Change

Problem: The maximum ICCD increases from 20 µA to 25 µA. The following in the revised ICCD specifi-

cation:

Implication: The maximum ICCD is specified under worst case conditions only (VCC = 3.6 V, temperature =

+85 °C). The typical ICCD specification should be used to determine ICCD current draw under

typical conditions (VCC = 3.3 V, temperature = +25 °C). The typical ICCD specification has not

changed.

Status: Refer to the Summary Tables of Changes to determine the affected stepping(s)

Errata

6. 28F320B3TC Block Locking Failure

Problem: For the 0.18µm 32 M-bit top boot devices affected by this erratum, block locking functionality

deviates from the datasheet specification. WP#=VIL protects blocks #63 and #64, instead of blocks

#69 and #70).

Implication: There are two implications to this erratum:

1) The two Lockable Parameter Blocks (blocks #69 and #70) are not protected when WP#=VIL;

and

2) When WP#=VIL, blocks #63 and #64 will be locked, and any attempts to program or erase these

two blocks may fail.

Workaround: There are two workarounds for this erratum:

1) Set WP#=VIH when programming or erasing blocks #63 and #64. In addition, hold VPP≤VPPLK

when not programming or erasing for additional protection against accidental writes; and

2) Temporarily, have software swap the contents of blocks #63 and #64 with the contents of blocks

#69 and #70. If code was originally in blocks #69 and #70, utilize jump routine to blocks #63 and

#64.

Status: This erratum affects all 0.18µm 28F320B3 top boot devices. A fix has been identified for this

erratum and is intended to be implemented in a future microcode revision.

7. 28F320B3xC Reset Failure

Problem: The 0.18µm 28F320B3xC 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) are equal or greater than “23”,

then VCC may be set from 2.7 V to 3.3 V. VCC must not exceed 3.3 V.

3) Set VPP to a static high or static low level as shown here; and

4) Wait 2 ms after a VPP transition to access the flash device as shown here.

Problem: On the 0.18µm 28F640B3xC device, the maximum ICCS and ICCD deviates from the published

Errata

9. 28F160B3xC Erase Resume Issue

Problem: On the 0.18µm 28F160B3xC device, 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 listed in

Table-1 after issuing the Program (40H/10H) and data sequence but before issuing the Erase-

Resume (D0H) command.

Specification Changes

1. 0.25µm 32-Mb Maximum VCC Change

Issue: The maximum VCC decreases from 3.6 V to 3.3 V on 0.25µm32-Mb versions only. The following

table shows the revised VCC specification.

Other implied specification changes, as a result of the VCC change, are described in the following

table:

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, or devices on the 0.18µm process. 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.
