1 i.MX 7ULP modules list

The i.MX 7ULP applications processor contains a variety of digital and analog

modules. The following table describes these modules in alphabetical order.

In the Domain column in this table:

• AD = Application Power Domain (primarily controlled by the Cortex-A7)

• RT = Real-Time Power Domain (primarily controlled by the Cortex-M4)

• VBAT = RTC/VBAT power domain Real-Time Domain

• DGO = “always-on” DGO power domain

• SYS = system-level functions that are implemented separately from the domains

listed above.

Brief description

AMBA Network

Interconnect

Crossbar

NIC0-1

DMA and Bus Fabrics AD

The AMBA Network Interconnect

Crossbar (NIC) is a highly configurable

and high performance AMBA-compliant

network infrastructure which arbitrates

between multiple AXI or AHB masters to

grant access to internal or external

memories or other slave devices. It

supports connectivity between several

slave and master ports for parallel

processing. It uses a hybrid round-robin

arbitration scheme and contains

frequency converters, data width

converters, bus protocol converter, and

AXI channel buffers.

Analog PMC

Power Management

SYS

The Analog PMC consists of voltage/

current references, core logic supply

regulators, memory supply regulators,

Back and Forward Biasing regulators,

monitors and power switches, etc.

There are two Analog PMC subsystems

in i.MX 7ULP, one associated with the

M4 power domain and the other with the

A7 power domain.

Analog-to-Digital

Converter

ADC0-1

Analog

Analog-to-Digital Converter (ADC) is a

12-bit resolution, successive

approximation analog to digital

converter. The ADC module supports

up to 16 single-ended external analog

inputs. It outputs 12-bit, 10-bit, or 8-bit

digital signal in right-justified unsigned
