About the Modules

CHAPTER 1
The ConnectCore 9C and ConnectCore Wi-9C modules are powerful ARM9-based
modules in a compact and universal SO-DIMM (Small Outline Dual Inline Memory Module) form factor. The modules provide core processing functionality with integrated wired and wireless network connectivity and a complete set of peripheral options in a footprint-compatible interchangeable SO-DIMM form factor that allows you to optimize your system for either Ethernet, WLAN, or both.
The ConnectCore 9C provides 10/100 Ethernet connectivity only. The ConnectCore Wi-9C provides both 10/100 Ethernet and 802.11b/g wireless
networking capabilities. All modules are fully compliant with EU directive 2002/95/EC (RoHS).

The Ethernet connector is an 8-wire RJ-45 jack with integrated magnetics that meets the ISO 8877 requirements for 10/100BASE-T. The connector provides both Ethernet interface pins (in the upper portion) and two integrated LEDs (in the lower portion).
Ethernet port
Ethernet connector pins
There are eight Ethernet connector pins in the upper portion of the connector. Pin 1 is in the upper left corner of the connector, above the yellow LED. Pins 4, 5, 7, and 8 are used with Power-over-Ethernet (PoE) only (see “802.3af Power over Ethernet (PoE) pass-through connector, P5” on page 13).

The PoE pass-through connector, P5, mates with the P20 header on the development board. This PoE pass-through feature passes P oE power connections from the Ethernet signal cable to the user’s equipment through P5. The P oE feature provides a power source for compliant “powered” equipment, and is nominally 48VDC with a possible 30–57VDC 13 W maximum range.

By default, the ConnectCore 9C/Wi-9C modules use the CR1 and CR2 LEDs as described:
ConnectCore Wi-9C module: To indicate WLAN-related information, such as
association status and network activity.
ConnectCore 9C and Wi-9C modules: CR1 will flash a repeating blink pattern
in a major system failure; for example, a processor exception or Power on Self Test failure.
The ConnectCore Wi-9C LED assignments can be reassigned; that is, you can use different GPIOs to drive CR1/CR2 LEDs.

The JTAG connector is a standard, male, ARM 20-pin pinout in a miniature connector, with a 50-mil pitch. A JTAG adapter, which ships with each Jump Start kit, expands the JTAG connector to a 100 mil pitch. Use the included JT AG adapter to connect the debugger.
The JTAG connector on the module is keyed, as are the two connectors on the JTAG adapter, which means there is only one way to attach ribbon cables to the module and JTAG adapter. For details, see “JTAG adapter assembly” on page 16.

Use the JT AG adapter assembly, shipped with the ConnectCore 9C/Wi-9C Jump Start Kit, to attach your debugger to the module. The JTAG adapter assembly consists of the Digi JTAG Link USB debugger with a ribbon cable attached and the JTAG adapter with a ribbon cable attached. The Jump Start Kit also includes a USB cable.
The two connectors on the JTAG adapter are keyed, as is the JTAG connector header (P2) on the module. Keyed connectors eliminate cable attachment errors by ensuring that there is only one way to mate the connectors.
JTAG adapter The JTAG adapter has two 20-pin connectors, P1 and P2.
P1 is a keyed male connector into which you attach the debugger’s ribbon
cable.
P2 is a keyed male connector into which you attach the ribbon cable that plugs
into the module.
J1 is a jumper that determines the mode in which the module operates: debug
or boundary scan. Depending on the JTAG adaptor you are using, J1 has either two pins or three pins.
This drawing shows the JTAG adapter with a 2­pin J1 header.
For debug mode — Do not plug a jumper onto J1. For boundary scan mode — Plug a jumper onto
J1.

This drawing shows the JTAG adapter with a 3­pin J1 header. The pin positions for debug and boundary scan are shown in the lower right of the drawing:
For debug mode — Plug a jumper on pins 1 and
2. For boundary scan mode (the default) — Plug a
jumper on pins 2 and 3.

1 Plug the
debugger ribbon cable into the connector labeled P1 on the JTAG adapter.
2 Plug the
adapter ribbon cable (attached to P2 on the adapter) into the P2 connector on the module.
Step 2: Plug this end of the cable into the P2 connector on the module.

The edge connector is a 144-pin SO-DIMM connector located on the short edge of the module. P3 mates with P15 (also a 144-position SO-DIMM connector) on the development board or an SO-DIMM connector on your design.

Note:
Pin assignment The next tables show information for all pins on the edge connector, in DIMM pin
order. For additional SO-DIMM pin characteristics, see "Module / SO-DIMM signal characteristics," beginning on page 70.
The clearance underneath the module and development board should be
2.54mm (0.10”).
Some signals are multiplexed to two different GPIO pins, to maxim ize the
number of possible applications. The primary/duplicate signals are noted in

the Notes column in the table. Using the primary GPIO pin and the duplicate pin for the same function is not recommended.
Note: Functions in parentheses are duplicates; for exampl e, p in 63 h a s two entries in the LCD column: CLD6 and (CLD10). CLD10 is a duplicate signal for pin 63; the Notes column identifies the primary function for that signal.
A # next to a signal indicates that this signal is active low. A bold value in the System / Other / Bootstrap column indicates the bootstrap
signal.
