Connector to Motherboard

To connect between motherboard and IO48 NAND Flash daughter card, Samtec QSH/QTH series connectors are applied. Samtec QTH-030 60-pin connector is used on IO48 NAND Flash daughter card side while Samtec QSH 60-pin is at the motherboard side.

10/100/1000 Mbps Ethernet PHY

This daughter card supports copper RJ-45 10/100/1000 Mbps Ethernet using an external Ethernet PHY Microchip KSZ9031RNX. The PHY-to-MAC interface employs RGMII using Intel® Stratix® 10 SoC IO48 EMAC2 to transmit and receive data. For management interface, it uses MDC/MDIO interface between EMAC2 and Ethernet PHY.

NAND Flash

The IO48 NAND flash daughter card supports a 16-bit NAND flash. Since some NAND flash pins are multiplexed with eMMC pins, NAND flash and eMMC flash cannot be used simultaneously. There are MUX resistors to select related IO48 signals are connected to NAND flash or eMMC flash. The default setup is NAND flash.

The proposed NAND flash memory is MT29F8G16ADBDAH4-AIT:D manufactured by Micron. Major parameters are as listed below:

Paramater Description
Type SLC NAND
Density 8 Gb
Data Width 16-bit
Voltage 1.8 V

Operational Temperature -40 C to +85 C

An optional NAND socket can be used for easy NAND Flash replacement when NAND flash is not soldered down. The socket vendor is Ironwood with part number SG-BGA-6367.

eMMC

The IO48 NAND flash daughter card also supports a 8-bit eMMC flash. Since the eMMC flash pins are multiplexed with NAND pins, NAND Flash and eMMC Flash cannot be used simultaneously. There are MUX resistors to select related IO48 signals are connected to NAND flash or eMMC flash. The default setup is NAND flash, not eMMC.

The proposed eMMC flash memory is MTFC8GAKAJCN-4M IT manufactured by Micron.

Power

There are two power rails drawn from motherboard through Samtec connector VCC_12V and VCCIO_HPS. VCC_12V is major power source and it is converted to other power rails with on-board regulators. It is recommended to have at least 1 A capability on VCC_12V power rail.

VCCIO_HPS is HPS I/O buffers power supply from motherboard.
