NXP Semiconductors

LPSPI1

LPSPI2

LPSPI3

LPSPI4

Low Power Serial

Peripheral Interface

Connectivity and

Communications

The LPSPI is a low power Serial Peripheral Interface

(SPI) module that support an efficient interface to an

SPI bus as a master and/or a slave.

• It can continue operating while the chip is in stop

modes, if an appropriate clock is available

• Designed for low CPU overhead, with DMA off

loading of FIFO register access

LPUART1

LPUART2

LPUART3

LPUART4

LPUART5

LPUART6

LPUART7

LPUART8

UART Interface

Connectivity

Peripherals

Each of the UART modules support the following serial

data transmit/receive protocols and configurations:

• 7- or 8-bit data words, 1 or 2 stop bits, programmable

parity (even, odd or none)

• Programmable baud rates up to 5 Mbps.

MQS

Medium Quality Sound

Multimedia

Peripherals

MQS is used to generate 2-channel medium quality

PWM-like audio via two standard digital GPIO pins.

QuadTimer1

QuadTimer2

QuadTimer

Timer Peripherals

The quad-timer provides four time channels with a

variety of controls affecting both individual and

multi-channel features.Specific features include

up/down count, cascading of counters, programmable

module, count once/repeated, counter preload,

compare registers with preload, shared use of input

signals, prescaler controls, independent

capture/compare, fault input control, programmable

input filters, and multi-channel synchronization.

ROMCP

ROM Controller with

Patch

Memories and

Memory Controllers

The ROMCP acts as an interface between the Arm

advanced high-performance bus and the ROM. The

on-chip ROM is only used by the Cortex-M7 core during

boot up. Size of the ROM is 96 KB.

RTC OSC

Real Time Clock

Oscillator

Clock Sources and

Control

The RTC OSC provides the clock source for the

Real-Time Clock module. The RTC OSC module, in

conjunction with an external crystal, generates a 32.678

kHz reference clock for the RTC.

RTWDOG

Watch Dog

Timer Peripherals

The RTWDG module is a high reliability independent

timer that is available for system to use. It provides a

safety feature to ensure software is executing as

planned and the CPU is not stuck in an infinite loop or

executing unintended code. If the WDOG module is not

serviced (refreshed) within a certain period, it resets the

MCU. Windowed refresh mode is supported as well.

SAI1

SAI2

SAI3

Synchronous Audio

Interface

Multimedia

Peripherals

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.

SA-TRNG

Standalone True Random

Number Generator

Security

The SA-TRNG is hardware accelerator that generates

a 512-bit entropy as needed by an entropy consuming

module or by other post processing functions.
