P1-P3P4-P6P7-P9P10-P10
General Description
The MAX3420E evaluation kit-2 (EV kit-2) provides a
proven design to evaluate the MAX3420E USB peri-
pheral controller with SPI™ interface. The EV kit-2
board is jumper-connected to an Atmel
®
ATtiny2313
microcontroller by default, but can also be connected
to any SPI master. The MAX3420E EV kit-2 adds USB
functionality to any microcontroller, microprocessor,
DSP, CPLD, FPGA, or ASIC with an SPI master inter-
face or five GPIO lines can connect to the MAX3420E
EV kit-2.
The EV kit-2 board comes with the MAX3420EECJ+
installed.

Quick Start
Recommended Equipment
• MAX3420 EV kit-2 (USB cable included)
• A user-supplied Windows
®
2000/XP PC with spare
USB port
Note: In the following sections, software-related items
are identified by bolding. Text in bold refers to items
directly from the EV kit software. Text in bold and
underlined refers to items from the Windows 2000/XP
operating system.
Procedure
The MAX3420E EV kit-2 is fully assembled and tested.
Follow the steps below to verify board operation.
1) Verify that all jumpers (JU1–JU11) are in the default
1-2 position.
2) Connect the included USB cable from the PC’s
USB port (Type A) to the USB connector (Type B)
on the MAX3420E EV kit-2 board.
3) Verify that the red USB power LED (D5) lights up.
4) Verify that the green port 0 LED (D1) blinks.
5) A Found New Hardware | Demo
window appears
after plugging in the USB cable for the first time
(Figure 1). Windows 2000 or higher is required.
6) Next, a Found New Hardware | USB Human
Interface Device appears, as shown in Figure 2.
The standard Windows USB HID driver is installed
automatically.
7) Open WordPad by clicking on the WordPad icon
located at Start | Programs | Accessories |
WordPad. Caution: Make sure that WordPad or a
similar editor (e.g., Notepad) is the active window
before performing the next step (the demonstration
program types text into whatever window is open).
8) Press the port 3 pushbutton switch (SW4) to start
the HID keyboard emulator.
9) Verify that the HID keyboard emulator automatically
writes text into the active WordPad editor.
10) Stop the HID keyboard emulator by pressing the
port 3 pushbutton switch (SW4) again. The port 3
pushbutton starts and stops the emulator.

Detailed Description of Hardware
Tables 1 and 2 describe the function of each pushbutton
and LED during the HID keyboard emulator demo.
Tables 3 through 6 explain the functionality of each
jumper on the MAX3420E EV kit-2.
Tables 7 through 9 give the pin descriptions for headers
H1, H2, and H3. H2 is a header consisting of SPI test
points. H3 is a header designed to be connected to
one of two Atmel tools. The JTAGICE-2 can connect to
this header to load and debug ATtiny2313 code using
the AVR Studio® software, available on the Atmel web-
site. Additionally, an AVRISP-2 can be connected to
program any hex file into the ATtiny2313. Refer to the
Atmel documentation for further details.
The example firmware code for the HID keyboard emula-
tor may be downloaded at www.maxim-ic.com/evkitsoft-
ware. Double click the MAX3420E EVKIT Firmware link.
