1.1 EVM Revisions and Assembly Variants

The various AM64x/AM243x EVM PCB design revisions, and assembly variants are listed in the table below. Specific PCB revisions are indicated in silkscreen on the PCB. Specific assembly variants are indicated with additional sticker labels.

Table 1-1 AM64x/AM243x EVM PCB Design Revisions, and Assembly Variants
PCB RevisionAssembly VariantRevision and Assembly Variant Description
PROC101-004 CN/AFirst Production Release of the AM64x EVM
PROC101-005 C N/A First Production Release of the AM243x EVM
PROC101-004 D N/A Second Production Release of the AM64x EVM. Implements a number of changes and bug fixes
PROC101-005 D N/A Second Production Release of the AM243x EVM. Implements a number of changes and bug fixes
PROC101-004 D-1 N/A Third Production Release of the AM64x EVM. Functionally equivalent to PROC101-004 D with only minimal BoM change. No PCB Design modifications
PROC101-005 D-1 N/A Third Production Release of the AM243x EVM. Functionally equivalent to PROC101-005 D with only minimal BoM change. No PCB Design modification
Note: Throughout this document, the AM6442 and AM2434 devices are interchangeable in diagrams and other tables, other than explicitly defined exception. The AM2434 MCU in the ALV package and the AM6442 MPU are footprint and pinout compatible and the PCB has been designed to accommodate both.
Note: For the board formerly known as AM64x/AM243x GP EVM, please see AM64x/AM243x EVM User's Guide (Rev. D)
Note: All AM64x/AM243x EVMs include high-security field-securable (HS-FS) silicon to customize keys and encryption for security applications.
