2.6.7.1 LPDDR4 Interface

The AM62D Audio EVM houses the dual-rank, dual-die 4GB, 32-bit wide LPDDR4 memory (MT53E1G32D2FW-046 IT:C) from Micron supporting data rates up to 3733MT/s. The LPDDR4 memory is placed optimally and routed to the DDR0 group of the SoC to support point-to-point communication.

The LPDDR4 memory requires 1.8V for its core supply, thus reducing power demand. The I/Os are supplied from a 1.1V supply output from the PMIC. LPDDR4 reset (Active low) controlled by the AM62D SoC is pulled down to set the default active state. The provision for mounting a pull up resistor is also provided.
