Chapter 1
Introduction

The i.MX27 3-Stack Platform System helps you develop new solutions using the i.MX27
ARM9™ MCU and the MC13783 audio and power management chip.

The 3-Stack platform comprises the CPU Engine board, Personality board, and Debug board. The
system suppo r ts application software development, target bo ar d debugging, and optional circuit
cards. The CPU board can be run in stand-alone mode for code development. An LCD display
panel is supplied with the 3-Stack system.

Figure 1-1 shows the major components of the 3-Stack system.

Freescale Semiconductor i.MX27 PDK 1.0 Hardware User's Guide, Rev. 1.0 1-1

1.1 i.MX27 3-Stack Features

The 3-Stack system can be used in two ways: the development mode requires a three-board
as sembly; the d emons tratio n mode r eq uires only a two-board assembly (without th e Debug
board).

The system includes the following features

.

• Near form-factor demonstration modules and working platforms.

• Solid reference schematics that closely resemble final products to aid customers’ designs.

• Three-board system, which includes:
⎯ CPU board with i.MX27 ARM9 MCU, MC13783 chip
⎯ Personality boar d with peripheral components and interface connectors
⎯ Debug board with two RS-232 interfaces, 10/100 Base-T Ethernet connector, and

current measure connectors.

• Utilizes reliable high-density connector to interface between boards.

Fig ure 1- 2 illu str ates the three-board assembly (left) fo r dev elop ment and th e tw o-boar d a ssembly
(right) for demonstration.

Configuration and Connections

This section contains configuration information, connection descriptions, and other operational information
that may be useful during the development process.

2.1 Debug Board Configuration

Th e D ebug bo ard pro vides an easy, familia r inter face for pr ogramming and debugging the i.MX
development systems and reference platforms.

This section describes the switches and connectors o n t he t op of the Debug board, and the connector to t he
CPU Engine bo ar d on the bott om of the Debug board. The Debug board is a small card that you can insert
o r remov e fr om th e p latfor m. The ab ility to remov e the debug bo ard is a major ad van tage to marketing a nd
sa les tea ms who want to d emonst rate and sh owcase a varie ty of pro ducts an d id ea s in a streamlined, nea r
form factor way, without t he added software development bulk.
