About the Embedded Modules

CHAPTER 1

Overview

The Digi Connect Wi-ME 9210 and Digi Connect ME 9210 b/g/n is a fully customizable and secure

802.11b/g/n wireless embedded module that provides integration flexibility in a variety of

connection options. Built on the new Digi NS9210 processor in combination with a 802.11b/g/n Wi-

Fi radio, it is pin-compatible with the existing Digi Connect Wi-ME 7520 and Digi Connect ME

7520 802.11b module allowing customers to easily migrate to the next-generation version of the

product.

The Digi Connect ME 9210 is an ultra-compact embedded module based on Digi’s powerful 75

MHz NS9210 processor. It allows customers to implement the next generation of leading network-

enabled products and maintains full form factor and pin-compatibility with the existing Digi

Connect ME family.

The NS9210 processor provides a host of features such as an ARM926EJ-S core running at speeds

from 75-150MHz, on-chip AES encryption engine, one PIC, a serial port, SPI and I2C interfaces,

PWM, and others. Most importantly, it is a “drop-in” replacement for the NS7520, which means that

is the ideal upgrade vehicle to deliver a next-generation design.

The integrated FIM on the NS9210 processor offer interface flexibility allowing the modules to

provide high performance interface functionality and unique software-driven configuration

flexibility by dynamically loading software support for application specific interfaces, e.g. UART,

CAN, USB device, 1-Wire, SDIO, and others.

The Digi Connect Wi-ME 9210 and Digi Connect ME 9210 embedded module offers freedom and

flexibility of professional embedded software development provided by the easy-to-use, cost-

effective and complete Digi JumpStart Kits™.

From medical systems to building control and industrial automation, in virtually any application

where embedded device connectivity over a wireless network is needed, embedded modules are the

ideal choice, delivering high-performance functionality.

Note:

Unless mentioned specifically by name, the products will be referred to as the embedded

modules or modules. Individual naming is used to differentiate product specific features.

This chapter provides information about the modules hardware and contains the following topics:

Types of Modules

There are two types of modules. One module utilizes Digi Plug-and-Play Firmware, while the

second is customizable with the option to develop a firmware application in NET+OS. If you are

developing your firmware application in NET+OS, you will be using a module with a JTAG

interface.

Note:

JTAG is a commonly used term that is also referred to as IEEE 1149.1, an industry standard

test protocol. JTAG is an abbreviation for the European Joint Test Action Group, which

invented the first versions of the IEEE 1149.1 interface. The JTAG interface, along with the

other development tools, enables you to download, run and debug programs on the module.

The following figures show the two types of modules.

Note:

-S: No JTAG for use with Digi Plug-and-Play Firmware

-C: No JTAG for use with custom NET+OS applications

-JT: With JTAG for use with custom firmware development
