7.2 DDR4 SDRAM
The TE0808-04 SoM is equipped with with four DDR4-2400 SDRAM modules with up to 8 GByte memory density. The
SDRAM modules are connected to
the Zynq
MPSoC's PS DDR controller (bank 504) with a 64-bit data bus.
Refer to the Xilinx Zynq Ult datasheet
for more information on whether the specific package of the
Zynq Ult MPSoC supports the maximum data transmission rate of 2400 MByte/s.
