Memories Supported
The AM571x 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 AM571x IDK EVM design supports a single bank of DDR3L SDRAM that is attached to the EMIF on
the AM5718 processor. The EMIF can support up to 2GB of DDR3L SDRAM memory at speeds up to
1333MT/s. The SDRAM implemented on the EMIF on the IDK EVM contains two 4Gbit (256M × 16)
SDRAMs for a total of 1GB of DDR3L SDRAM memory. 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
AM571x Sitara Processors Technical Reference Manual (SPRUHZ7)
for
memory locations for this memory.
The 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 AM571x devices. Refer to the
AM571x Sitara Processors
Silicon Errata (SPRZ436)
for more details.
5.2
SPI NOR Flash
The AM571x 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 AM5718 device.
5.3
Board Identity Memory
Each of the AM571x 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
Section 4
for details on the data stored in this memory.
5.4
SD/MMC
The SD/MMC connector on the AM571x 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 AM571x
processor that is optimized for this use. Refer to the
AM571x Sitara Processors Silicon Revision 2.0 Data
Manual (SPRS957)
and the
AM571x Sitara Processors Technical Reference Manual (SPRUHZ7)
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 AM571x 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.
