Modules list

ENC

Quadrature

Encoder/Decoder

Timer Peripherals

The enhanced quadrature encoder/decoder module

provides interfacing capability to position/speed

sensors. There are five input signals: PHASEA,

PHASEB, INDEX, TRIGGER, and HOME. This module

is used to decode shaft position, revolution count, and

speed.

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

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

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 RT1015 has 128 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 128 KB on-chip RAM

array. Major functions of this blocks are: interfacing to

I-TCM and D-TCM of Arm core and OCRAM controller;

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

OCRAM.

FlexSPI

Quad Serial Peripheral

Interface

Connectivity and

Communications

FlexSPI acts as an interface to one or two external

serial flash devices, each with up to four bidirectional

data lines.

GPIO1

GPIO2

GPIO3

GPIO5

General Purpose I/O

Modules

System Control

Peripherals

Used for general purpose input/output to external ICs.

Each GPIO module supports up to 32 bits of I/O.
