RLDRAM3 Devices (U31, U36)

You can use the two 16 Mbx36 RLDRAM3 memory devices (Micron MT44K32M18RB-093)

soldered on the board. The HD1000 drives the memory signals using dedicated GPIOs.

Although you may repurpose these IO pins, Bank West-South (Byte 0 – 12), on your designs,

you must maintain the allocation shown in Table 14 to use the devices provided on the

board.

Note: Do not reallocate these Ios on the ACX-BRD-HD1000-100G development board. This could

lead to unexpected behavior.

Note: Table 14 shows only the logical connection for application development. Relevant voltage levels

are driven on the board by additional circuitry.
