NXP Semiconductors

ENET

Ethernet Controller

Connectivity

Peripherals

The Ethernet Media Access Controller (MAC) is

designed to support 10/100 Mbit/s 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 reference manual for details.

ENET 1G

Ethernet Controller

Connectivity

Peripherals

One 1G Ethernet is also integrated, which has following

features:

• RGMII/RMII/MII operation

• Support IEEE1588

• Support AVB

EWM

External Watchdog

Monitor

Timer Peripherals

The EWM modules is designed to monitor external

circuits, as well as the software flow. This provides a

back-up mechanism to the internal WDOG that can

reset the system. The EWM differs from the internal

WDOG in that it does not reset the system. The EWM, if

allowed to time-out, provides an independent trigger pin

that when asserted resets or places an external circuit

into a safe mode.

FlexIO1

FlexIO2

Flexible Input/output

Connectivity and

Communications

The FlexIO is capable of supporting a wide range of

protocols including, but not limited to: UART, I2C, SPI,

I2S, camera interface, display interface, PWM

waveform generation, etc. The module can remain

functional when the chip is in a low power mode

provided the clock it is using remain active.

FlexPWM1

FlexPWM2

FlexPWM3

FlexPWM4

Pulse Width Modulation

Timer Peripherals

The pulse-width modulator (PWM) contains four PWM

sub-modules, each of which is set up to control a single

half-bridge power stage. Fault channel support is

provided. The PWM module can generate various

switching patterns, including highly sophisticated

waveforms.

FlexRAM

RAM

Memories

The i.MX RT1160 has 512 KB of on-chip RAM which

could be flexible allocated to I-TCM, D-TCM, and

on-chip RAM (OCRAM) in a 32 KB granularity. The

FlexRAM is the manager of the 512 KB on-chip RAM

array. Major functions of this blocks are: interfacing to

I-TCM and D-TCM of CM7 and OCRAM controller;

dynamic RAM arrays allocation for I-TCM, D-TCM, and

OCRAM.

FlexSPI1

FlexSPI2

Flexible Serial Peripheral

Interface

Connectivity and

Communications

FlexSPI acts as an interface to one or two external serial

memory devices, FlexSPI2 has 8 bi-directional data

lines.
