DDR3L Memory

The element14 BeagleBone Black uses a single MT41K256M16HA-125 512MB DDR3L

device from Micron that interfaces to the processor over 16 data lines, 16 address lines,

and 14 control lines. The following sections provide more details on the design.

6.2.6 Memory Device

The design supports the standard DDR3 and DDR3L x16 devices and us built using the

DDR3L. A single x16 device is used on the board and there is no support for two x8

devices. The DDR3 devices work at 1.5V and the DDR3L devices can work down to

1.35V to achieve lower power. The specific Micron device used is the

MT41K256M16HA-

125

. It comes in a 96-BALL FBGA package with 0.8 mil pitch. Other standard DDR3

devices can also be supported, but the DDR3L is the lower power device and was chosen

for its ability to work at 1.5V or 1.35V. The standard frequency that the DDR3L is run at on

the board is 400MHZ.
