Modules list

OCOTP_CTRL

OTP Controller

The On-Chip OTP controller (OCOTP_CTRL) provides an interface

for reading, programming, and/or overriding identification and control

information stored in on-chip fuse elements. The module supports

electrically programmable poly fuses (eFUSEs). The OCOTP_CTRL

also provides a set of volatile software-accessible signals that can be

used for software control of hardware elements, not requiring non

volatility. The OCOTP_CTRL provides the primary user-visible

mechanism for interfacing with on-chip fuse elements. Among the

uses for the fuses are unique chip identifiers, mask revision

numbers, cryptographic keys, JTAG secure mode, boot

characteristics, and various control signals requiring permanent non

volatility.

OCRAM

On-Chip Memory controller

The On-Chip Memory controller (OCRAM) module is designed as an

interface between the system’s AXI bus and the internal (on-chip)

SRAM memory module.

In i.MX 8M Plus processors, the OCRAM is used for controlling the

868KB multimedia RAM through AXI bus.

PCIe

PCI Express 3.0

The PCIe IP provides PCI Express Gen 3 functionality.

PMU

Power Management Unit

Integrated power management unit. Used to provide power to

various SoC domains.

PWM1

PWM2

PWM3

PWM4

Pulse Width Modulation

The pulse-width modulator (PWM) has a 16-bit counter and is

optimized to generate sound from stored sample audio images. It

can also generate tones. It uses 16-bit resolution and a 4x16 data

FIFO to generate sound.

SAI1

SAI2

SAI3

SAI5

SAI6

SAI7

Synchronous Audio Interface

The SAI module provides a synchronous audio interface (SAI) that

supports full duplex serial interfaces with frame synchronization,

such as I2S, AC97, TDM, and codec/DSP interfaces.
