Memories Supported
The AM572x IDK EVM supports on-board memories including DDR3L SDRAM, SPI NOR Flash, eMMC
NAND Flash, and I2C SEEPROM. It also supports a MicroSD card socket that can add memory storage.
5.1
DDR3L SDRAM
The AM572x IDK EVM design supports two banks of DDR3L SDRAM where each is attached to a
separate EMIF on the AM5728 processor. Each EMIF can support up to 2GB at speeds up to 1066MT/s.
Each EMIF on the IDK EVM contains two 4Gbit (256M × 16) SDRAMs for a total of 1GB of DDR3L
SDRAM memory on each EMIF. The part number for the DDR3L SDRAM memory used is
MT41K256M16HA-125 that contains timing for 1600MT/s operation. The package used is the 96-ball
TFBGA package. See the
AM572x Sitara Processors Technical Reference Manual (SPRUHZ6)
for
memory locations for this memory.
The first EMIF also contains an SDRAM attached to the ECC byte lane. Use of ECC on the DDR3L
interface is currently highly constrained by limitations in the AM572x devices. Refer to the
Processors Silicon Errata (SPRZ447)
for more details.
5.2
SPI NOR Flash
The AM572x IDK EVM supports a 256Mbit (32MB) SPI Flash Memory from Spansion (S25FL256S) in a
16-pin SOIC package. It is connected to the QSPI port of the AM5728 device.
5.3
Board Identity Memory
Each of the AM572x IDK EVM boards contains a 256Kb (32KB) Serial EEPROM that contains board-
specific data. This data allows the application software to automatically detect the type of board that it is
running on and also to determine its version and, potentially, optional features. Other hardware specific
data can be stored on this memory device as well. The part number of the memory device is
CAT24C256WI-G in a SOIC-8 package. Refer to
for details on the data stored in this memory.
5.4
SD/MMC
The SD/MMC connector on the AM572x IDK EVM is a MicroSD connector (part number SCHA5B0200).
This is a standard SD/MMC card type of connector. It is connected to the MMC1 port of the AM572x
processor that is optimized for this use. Refer to the
AM572x Sitara Processors Silicon Revision 2.0 Data
and the
AM572x Sitara Processors Technical Reference Manual (SPRUHZ6)
for
supported card types and densities.
The SDWP input pin to the MMC1 port is connected to a 2-pin header, J44. The default state has the pin
pulled high. Shorting the header pulls the pin low. The polarity of this input is programmable; thus, the
hardware does not define whether a high or low level indicates Write Protest is active or not.
The transient protection implemented at the SDCARD connector is the TPD6E001.
5.5
eMMC NAND Flash
The MMC2 port on the AM572x processor supports eMMC memory devices, since it has 8 data lines. The
eMMC footprint is compliant with the JEDEC/MMC standard. Boards have been assembled and
successfully tested with the Kingston EMMC16G-S100 and the Micron MTFC16GAKAECN-2M WT. These
are 16GB eMMC NAND Flash memories that are standard version 5.0 compliant.
