Modules list

DDRC

Double Data Rate Controller

The DDR Controller has the following features:

• Supports 32-bit LPDDR4-4000 and DDR4-3200

• Supports up to 8 Gbyte DDR memory space

eCSPI1

eCSPI2

eCSPI3

Configurable SPI

Full-duplex enhanced Synchronous Serial Interface, with data rate

up to 52 Mbit/s. Configurable to support Master/Slave modes.

eDMA

Enhanced Direct Memory

Access

• There is one enhanced DMAs (eDMA).

• The eDMA is a 32-channel DMA engine

• It is provided specifically for copying between memory and

memory (most likely such as between two of DRAM, OCRAM_A,

and Audio DSPs TCM).

• It separates the 32 channels into separate 64 KByte regions in the

system memory map for virtualization and partitioning purpose.

• There are no DMA requests connected to eDMA from any

peripheral. It is generally controlled by the Audio DSP (or

potentially the Cortex-A53 or Cortex_M7).

ENET

Ethernet Controller

The Ethernet Media Access Controller (MAC) is designed to support

10/100/1000 Mbps Ethernet/IEEE 802.3 networks. An external

transceiver interface and transceiver function are required to

complete the interface to the media. The module has dedicated

hardware to support the IEEE 1588 standard. See the ENET chapter

of the

i.MX 8M Plus Applications Processor Reference Manual

(IMX8MPRM) for details.

ENET_QOS

Ethernet QoS Controller

The ENET_QOS is compliant with the IEEE 802.3–2015

specification and can be used in applications, such as AV bridges,

AV nodes, switches, data center bridges and nodes, and network

interface cards. It enables a host to transmit and receive data over

Ethernet in compliance with the IEEE802.3–2015.

A separate 1 Gbit Ethernet QoS with TSN supports the same

features as ENET and also following features:

• 802.1Qbv Enhancements to Scheduling Traffic

• 802.1Qbu Frame preemption

• Time Based Scheduling

FlexCAN1

FlexCAN2

Flexible Controller Area

Network

Communication controller implementing the CAN with Flexible Data

rate (CAN FD) protocol and the CAN protocol according to the CAN

2.0B protocol specification.

FlexSPI

The FlexSPI module acts as an interface to external serial flash

devices. This module contains the following features:

• Flexible sequence engine to support various flash vendor devices

• Single pad/Dual pad/Quad pad mode of operation

• Single Data Rate/Double Data Rate mode of operation

• Parallel Flash mode

• DMA support

• Memory mapped read access to connected flash devices

• Multi master access with priority and flexible and configurable

buffer for each master

GIC

Generic Interrupt Controller

The GIC handles all interrupts from the various subsystems and is

ready for virtualization.
