GPT

General Purpose Timer

Timer peripherals

Each GPT is a 32-bit “free-running” or “set and forget”

mode timer with programmable prescaler and compare

and capture register. A timer counter value can be

captured using an external event and can be configured

to trigger a capture event on either the leading or trailing

edges of an input pulse. When the timer is configured to

operate in “set and forget” mode, it is capable of

providing precise interrupts at regular intervals with

minimal processor intervention. The counter has output

compare logic to provide the status and interrupt at

comparison. This timer can be configured to run either

on an external clock or on an internal clock.

I2C1

I2C2

I2C3

I2C4

I2C Interface

Connectivity

peripherals

I2C provide serial interface for external devices. Data

rates of up to 320 kbps are supported.

IOMUXC

IOMUX Control

System control

peripherals

This module enables flexible IO multiplexing. Each IO

pad has default and several alternate functions. The

alternate functions are software configurable.

KPP

Key Pad Port

Connectivity

peripherals

KPP Supports 8x8 external key pad matrix. KPP

features are:

• Open drain design

• Glitch suppression circuit design

• Multiple keys detection

• Standby key press detection

LCDIF

LCD interface

Multimedia

peripherals

The LCDIF is a general purpose display controller used

to drive a wide range of display devices varying in size

and capability. The LCDIF is designed to support dumb

(synchronous 24-bit Parallel RGB interface).

MIPI-CSI

(two-lane)

MIPI Camera Interface

Multimedia

peripherals

This module provides a two-lane MIPI camera interface

operating up to a maximum bit rate of 1.5 Gbps.

MIPI DSI

(two-lane)

MIPI Display Interface

Connectivity

peripherals

This module provides a two-lane MIPI display interface

operating up to a maximum bit rate of 1.5 Gbps.

DDRC

DDR Controller

Connectivity

peripherals

The DDR Controller has the following features:

• Supports 16/32-bit DDR3/DDR3L, LPDDR3, and

LPDDR2-1066

• Supports up to 2 Gbyte DDR memory space

MQS

Medium-quality sound

module

Multimedia

peripherals

MQS is used to generate 2-channel, medium-quality,

PWM-like audio, via two standard digital GPIO pins.

The electronic specification is the same as the GPIO

digital output.
