2. Overview
2.1 Application Descriptions
The CDMA Wireless Data Module is a complex consumer communications instrument that relies
heavily on both digital signal and embedded processor technologies. The Wireless Data Modules
manufactured by AnyDATA.NET support Code-Division Multiple Access (CDMA). This operates in
both the cellular and PCS spectrum.
In a continuing effort to simplify the design and to reduce the production cost of the Wireless Data
Module, AnyDATA.NET has successfully developed the DT2000 series. The DT2000-Dual is
AnyDATA.NETs latest compact Wireless Data Module operating in the Cellular and PCS spectrum. The
DT2000-Dual also contains a complete digital modulation and demodulation system for CDMA standards
as specified in IS-95 A/B and IS-2000.
The subsystem in the DT2000-Dual includes a CDMA processor (MSM5100), an integrated
CODEC with an ear piece and microphone amplifiers, and an RS-232 serial interface supporting forward
link data communications at a rate of 230.4kbps.
The DT2000-Dual provides an external interface that includes the standard RS-232, Digital Audio,
External reset control, LCD Display, Keypad, and Ringer extension ports.
The DT2000-Dual has the capability to power down unused circuits in order to dynamically
minimize power consumption.

Notes:
* If not used as PCM, it can be used as a secondary UART for debugging. We strongly recommend that
the user has a 3-pin connector or 3 test points on their board, so that one can easily monitor and diagnose
their module.
** If the user wants the module to monitor battery voltage and the user is using a regulator in conjunction
with a battery, whose maximum voltage exceeds 4.3 V, to drive the module, then the user should please
contact our engineers.
When using a battery in which the voltage is between 3.3 V to 4.3 V and regulators arent used to drive
the module, leave this pin open.

4. Interface Descriptions
4.1 Overview
This chapter covers information required to convert the DT2000-Dual into a subscriber unit
application. In addition, some of the internal blocks of the device are described. Understanding these
internal blocks is necessary for one to completely grasp the functions of the various interfaces.
This chapter discusses the interface to the major blocks of the DT2000-Dual as shown in the
following figure. These blocks include:
n CODEC Interface
n UART Interface
n General Purpose Interface
n User Interface
n JTAG Interface

4.2 CODEC Interface
The CODEC Interface is configured by internal and external figures. If the internal CODEC
interface is used, additional glue logic is not necessary and the modules very simple audio interface can
be used. Otherwise if the internal CODEC interface is not used, an external CODEC is necessary to
support the car-kit system. In this case, the module provides a PCM CODEC Interface.
4.2.1 Internal CODEC Interface
The module contains analog audio interface circuitry. The contained audio interface supports all of the
required conversation and amplification stages for the audio front end.
The audio interface includes the amplification stages for both the microphone and earphone. The
interface supports one single-ended microphone input and one single-ended earphone output.

EAR_DET1 EAR/MIC Set Detect Logic Input (Pin No. 57) **
EAR_JACK+ Earphone Output Analog Output (Pin No. 60)
GND_A Audio Ground Audio Ground (Pin No. 59)
Note:
* MIC2, along with being a microphone input, checks to see if the user has pressed the headset key,
which allows the user to connect to or disconnect from a call. This pin is internally pulled high and is
therefore normally in the high state. To activate this input and connect to or disconnect from a call, the
user must set the MIC2 pin to a low state for 100ms to 200ms.
** EAR_DET1 checks to see if a headset has been connected to the ear-jack. When there is no headset
connected to the ear-jack, the audio path is disconnected. When a headset is connected to the ear-jack an
audio path is opened. To simulate a headset connected to the ear-jack, the user must apply a low signal to
the EAR_DET1 pin for as long as the user wants the audio path to be kept open.

4.3 UART Interface
4.3.1 Primary UART interface
The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that
conforms to the RS-232 Interface protocol. The module provides 3.0V CMOS level outputs and 3.0V
CMOS switching input levels. In addition, all inputs have a 5.0V tolerance, however 3.0V or 3.3V CMOS
logic compatible signals are highly recommended.
All the control signals of the RS-232 are active low, however the data signals, RXD and TXD, are
active high.
The UART has a 64 byte transmit (TX) FIFO and a 64 byte receive (RX) FIFO. The UART features
hardware handshaking, programmable data sizes, programmable stop bits, and odd, even, no parity. The
UART operates at a maximum bit rate of 115.2kbps.

4.3.2 Secondary UART interface
The secondary UART is used to monitor and diagnose the status of the DT2000-Dual. It is strongly
recommended for the user to have the following secondary UART pins connected to an extra connector or
to test points, in order to easily troubleshoot any problems with the module.

4.4 General Purpose Interface
The general purpose interface consists of 13 user-definable bi-directional pins.
Each GPIO pin can be configured as an input interrupt source. In addition, some GPIO pins can be
used as output control pins from the module. The user can define these pins properly as follows.

4.5 External Hardware Reset
There are two types of resets that the user can employ to restart the module. The first type will reset
the MSM and the memory and is performed when the user gives the AT command, AT+RESET, to the
MSM. Another way to reset the module is by using the external hardware reset. This type of reset will
reset the hardware as well as the MSM and the memory. The flash memory will be the only information
that is kept. To perform an external hardware reset, make sure the module has powered on and is not in

the initialization stage, and then apply a high signal of 2.5 V to 3.7 V to the external hardware reset pin
for 200ms to 500ms. Keep the external hardware reset pin low when the module is initializing as well as
during normal operation.
4.6 LEDs
The DT2000-Dual can indicate its current status through three pins. These three pins can be
connected to LEDs to more quickly and easily determine the status of the module. The SMS LED
indicates to the user if there is a SMS message or a voicemail message. If there is a SMS message or a
voicemail message, the SMS LED will turn on. After the user has read the SMS message or listened to the
voicemail message, the SMS LED turns off. Shortly after the module has been turned on, the Idle LED
should turn on indicating that the module is in-service. This means that the module is within the range of
the base station and is able to receive a signal from the base station. When the module is in traffic or
conversation stage, the Busy LED is on.

4.7 User Interface
4.7.1 Keypad
The keypad interface consists of a 4 X 5 matrix pattern. Only 4 of the 5-KEYSENSE/[4:0] pins are
used to connect a matrix keypad to the module. The KEYSENSE/ pins are active low.
5-GPIO pins are necessary to construct the other side of the matrix. These 5-GPIO pins must be active
high in order for the keypad matrix to work properly. The general keypad matrix is shown below:
