SPRSP98A November 2023 – June 2024 AM625SIP
PRODUCTION DATA
This section describes the AM625SIP device pins which have different power or signal functions relative to the ALW packaged AM6254 device. The AM6254 DDRSS0 signals in the ALW package that would normally connect to an external SDRAM were connected directly to an integrated LPDDR4 SDRAM in the AM625SIP device, and the pins associated with these signals were reassigned to different power or signal functions. Table 5-1 contains a list of ball numbers that were reassigned to new power or signal functions along with their new ball name and signal description.
