(SEPTEMBER 2022))

Page

• Global: Changed the document product status from "Advance Information" to "Production Data"................... 1

• (Features): Updated USB features to clarify speeds supported for device and host modes.............................. 1

• (Features): Updated the "Hardware integrity up to SIL 2 targeted" bullet to remove "for MCU domain" since

the new target includes both MCU and Main domains....................................................................................... 1

• (Applications): Added the linked Condition-Monitoring Gateway bullet.............................................................. 4

• (Functional Block Diagram): Updated note C to clarify USB speed limitations when shared SerDes PHY is

being used for PCIe............................................................................................................................................ 5

• (Device Comparison): Changed "Industrial Communication Subsystem Support" to "PRU_ICSSG Industrial

Communication Support" and changed content of notes associated with PRU_ICSSG to clarify PRU_ICSSG

features are still enabled on devices that do not enable Industrial Communication Support........................... 10

• (Device Comparison): Added a new note to clarify USB speed limitations when shared SerDes PHY is being

used for PCIe....................................................................................................................................................10

• (Pin Attributes - BALL STATE DURING RESET RX/TX/PULL and BALL STATE AFTER RESET RX/TX/

PULL): Added "NA: Not Applicable" to the description to help clarify the I2C Open-drain Fail-safe (I2C OD

FS) buffer type does not having internal pulls.................................................................................................. 14

• (Pin Attributes - Pins C19, A18, B18, E9, and A10): Changed the "PULL" value in the "BALL STATE DURING

RESET RX/TX/PULL" and "BALL STATE AFTER RESET RX/TX/PULL" columns from "Off" to "NA" to help

clarify the I2C Open-drain Fail-safe (I2C OD FS) buffer type does not having internal pulls........................... 17

• (Pin Attributes - Pin G18, J21, G19, K20, J20, J18, J17, H17, H19, H18, G17): Defined values in the "BALL

STATE DURING RESET RX/TX/PULL" and "BALL STATE AFTER RESET RX/TX/PULL" columns for each

pin..................................................................................................................................................................... 17

• (Pin Attributes - Pin F18): Removed the "PU/PD" value from the "PULL UP/DOWN TYPE" column since this

pin does not having internal pulls..................................................................................................................... 17

• (ADC0 Signal Descriptions): Updated note associated with ADC0_REFP and ADC_REFN to clarify

connectivity requirements................................................................................................................................. 59

• (DDRSS0 Signal Descriptions): Updated note associated with DDR_CAL0 to include maximum power

dissipation expected for calibration resistor......................................................................................................59

• (EQEP0 Signal Descriptions): Added a note and note references to identify each EQEP with a debounce

function on its input...........................................................................................................................................59

• (EQEP1 Signal Descriptions): Added a note and note references to identify each EQEP with a debounce

function on its input...........................................................................................................................................59

• (EQEP2 Signal Descriptions): Added a note and note references to identify each EQEP with a debounce

function on its input...........................................................................................................................................59

• (USB0 Signal Descriptions): Changed the maximum power dissipation expected for the USB0_RCALIB

calibration resistor from 7.5mW to 7.2mW........................................................................................................59

• (Pin Connectivity Requirements): Deleted pin J15 from the row associated with VDDS_MMC0..................... 94

• (Absolute Maximum Ratings): Defined values for all previously undefined TBD values.................................. 98

• (Absolute Maximum Ratings): Changed all 3.8V maximum values to 3.63V....................................................98

• (Absolute Maximum Ratings): Changed all 2.2V maximum values to 1.98V except MCU_PORz, which was

changed to 3.63V..............................................................................................................................................98

• (ESD Ratings): Replaced TBD values with tested values.............................................................................. 100

• (Speed Grade Maximum Frequency): Defined values for all previously undefined TBD values.................... 102

• (Power Consumption Summary): Added a link to the AM64x/AM243x Power Estimation Tool application note

........................................................................................................................................................................102

• (I2C OD FS Electrical Characteristics): Defined maximum VIH values for 1.8-V mode and 3.3-V mode and

included a note that describes how these values also define the absolute maximum input voltage. Removed

the typical Input Leakage Current value and several TBD values which were not applicable........................103

• (I2C OD FS Electrical Characteristics): Removed the typical Input Leakage Current value and several TBD

values which were not applicable................................................................................................................... 103
