Modules List

GPU2Dv1

Graphics

Processing

Unit-2D, ver. 1

Display

Peripherals

The GPU2Dv1 provides hardware acceleration for 2D graphic algorithms with

sufficient processor power to run desk-top quality interactive graphics

applications on displays up to HD1080 resolution.

I2C-1

I2C-2

I2C-3

I2C Interface

Connectivity

Peripherals

I2C provides serial interface for controlling peripheral devices. Data rates of

up to 400 kbps are supported.

OCOTP

Controller

On-chip OTP

controller

Security

Peripherals

The on-chip one-time -programmable (OCOTP) ROM serves the functions of

hardware and software capability bits, Freescale operations and unique-ID,

the customer-programmable cryptography key, and storage of various ROM

and general purpose configuration bits.

IOMUXC

IOMUX Control Slave

Connectivity

Peripherals

This module enables flexible I/O multiplexing. Each I/O pad has default as

well as several alternate functions. The alternate functions are software

configurable.

KPP

Keypad Port

Slave

Connectivity

Peripherals

The KPP supports an 8

× 8 external keypad matrix. The KPP features are as

follows:

• Open drain design

• Glitch suppression circuit design

• Multiple keys detection

• Standby key press detection

OWIRE

One-Wire

Interface

Slave

Connectivity

Peripherals

One-Wire support provided for interfacing with an on-board EEPROM, and

smart battery interfaces, for example, Dallas DS2502.

PWM-1

PWM-2

Pulse Width

Modulation

Slave

Connectivity

Peripherals

The pulse-width modulator (PWM) has a 16-bit counter and is optimized to

generate sound from stored sample audio images. It can also generate tones.

The PWM uses 16-bit resolution and a 4 x 16 data FIFO to generate sound.

RAM

128 Kbytes

Internal RAM

Internal

Memory

The On-Chip Memory controller (OCRAM) module, is an interface between

the system’s AXI bus, to the internal (on-chip) SRAM memory module. It is

used for controlling the 128 Kbyte multimedia RAM, through a 64-bit AXI bus.

ROM

96 Kbytes

Boot ROM

Internal

Memory

Supports secure and regular Boot Modes.

The ROM Controller supports ROM Patching.
