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.
