1.1 i.MX27 3-Stack Features

The 3-Stack system can be used in two ways: the development mode requires a three-board

assembly; the demonstration mode requires only a two-board assembly (without the 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 board 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.

Figure 1-2 illustrates the three-board assembly (left) for development and the two-board assembly

(right) for demonstration.
