1 Introduction

Ordering Information

The i.MX28 is a low-power, high-performance

applications processor optimized for the general

embedded industrial and consumer markets.The

core of the i.MX28 is Freescale's fast,

power-efficient implementation of the

ARM926EJ-S™ core, with speeds of up to

454 MHz.

See Table 1 on page 3 for ordering information.

The device is suitable for a wide range of

applications, including the following:

•

Human-machine interface (HMI) panels:

industrial, home

•

Industrial drive, PLC, I/O control display,

factory robotics display, graphical remote

controls

•

Handheld scanners and printers

Patient-monitoring, portable medical

devices

•

Smart energy meters, energy gateways

Media phones, media gateways

The integrated power management unit (PMU) on

the i.MX28 is composed of a triple output DC-DC

switching converter and multiple linear regulators.

These provide power sequencing for the device and

its I/O peripherals such as memories and SD cards,

as well as provide battery charging capability for

Li-Ion batteries.
