APPENDIX A: DOCUMENT REVISION HISTORY

TABLE A-1:

REVISION HISTORY

Revision

Section/Figure/Entry

Correction

DS00003591K (01-23-26)

Throughout document.

Part number updated to reflect D0 silicon revision.

Section 5.6.3, Auto-Down-

shift

Added new Auto-Downshift section.

Section 6.3, Power Con-

sumption

Power consumption values updated for D0 silicon

revision. All previous device mode condition mea-

surement criteria remains the same. Tables for both

“Minimum” and “Worst-Case” measurements

replaced with “Typical” power consumption tables.

Section 7.1, "Top Marking"

Added Top Marking section.

Product Identification Sys-

tem

Updated ordering code for industrial temperature

from “V” to “I”.

DS00003591J (08-07-25)

Throughout Document.

Miscellaneous grammatical and formatting

changes.

Throughout Document.

Digital Core (VDDCORE) and Analog Operation

(VDDAL) updated from “1.1V” to “1.21V”.

Section 3.3.1, Device Mode

Select (MODE_SEL[4:0])

Removed “preliminary and subject to change” note

regarding MODE_SEL[4:0] function.

Section 7.0, Package Out-

line

Updates made to Package Drawing, Dimensions,

and Land Pattern.

DS00003591H (12-05-24)

Throughout Document.

LDO Controller has been defeatured. Sections

detailing its operation have been removed or

updated. See below for further details.

Table 3-5, "Miscellaneous

Pins"

Description for LDO Controller Output (LDO_O)

has been changed from:

“On-chip +1.1V LDO controller output. This pin

drives the input gate of a P-channel MOSFET to

generate +1.1V for the device’s core voltages.

Note: If the system provides 1.1V, this pin is not

used and can be left unconnected.”

to: “On-chip +1.1V LDO controller output. This

functionality has been defeatured. The pin should

be left unconnected. Please refer to the errata for

further details.”

Section 4.1, "Voltage Regu-

lator and Power Connec-

tions"

This section have been modified. Text changed

from:

“The LAN8804D integrates an optional LDO con-

troller for use with an external P-channel MOSFET

to generate the 1.1V supply from an existing 2.5V

or 3.3V source. Use of the LDO controller and

MOSFET is not required. An external 1.1V supply

can be alternatively utilized.”

to: “The LAN8804D has an integrated LDO control-

ler. This controller has been defeatured. Please

refer to the errata for further details.”
