GENERAL DESCRIPTION
The DP1203 is a 30mm x 18mm shielded radio
transceiver module available for use in 433-435MHz,
868-870MHz or 902-928MHz ISM bands. The module
is suitable for circuit applications which have to satisfy
either European (ETSI EN300-220-1, EN301-489-3) or
the North American (FCC part 15.247, 15.249)
regulatory standards.
Small size 30mm x 18mm
Direct Digital Interface
Supply voltage 2.4V – 3.6V
Minimum frequency synthesizer step size of
500Hz
•
•
•
•
•
Maximum output power of +11dBm
Receiver sensitivity of -111dBm
Very high data rate up to 153.2kbps
Current consumption Tx = 62mA @ 11dBm
Current consumption Rx=14mA
Virtually no RF knowledge is required to use this RF
module. Wireless communication can be obtained with
just the addition of a suitable antenna and a
microcontroller. The DP1203 fulfils a wide range of
application requirements, ranging from basic point-to-
point communication to more complex multipoint
process control functions.
The module is suitable for surface mount reflow
assembly.
XEMICS provides basic firmware routines for
controlling the module and typical applications.

3. FUNCTIONAL DESCRIPTION
The DP1203 is a cost effective high performance radio transceiver module designed for the wireless transmission of
digital information over distances of >500 meters in free space.
The module is based on the RF transceiver circuit from Semtech, the XE1203. For more information on the XE1203,
please refer to the XE1203 datasheet, available from the Semtech website
http://www.semtech.com .
All high frequency circuits and the 39MHz reference crystal are enclosed inside a shielding can. The module
incorporates an antenna switch driven by two external pins (RX and TX), and a SAW Filter placed between the
antenna port (RF IN/OUT). The switch provides a superior margin to satisfy the European or the North American
regulatory standards.

4. SERIAL CONTROL INTERFACE
A 3-wire bi-directional bus (SCK, SI, SO) is used to control the DP1203. The output signal, SO, is provided by the
DP1203 in opposition to the SCK and SI which needs to be provided by the external application as an 8-bit
microcontroller. An access Read or Write with the XE1203 is possible only when the enable signal is active
(active LOW).
For more information about the 3-wire bus, please refer to the XE1203 datasheet chapter; Interface definition,
principles of operation. You can find this at http://www.semtech.com .

5. OPERATING MODES
The DP1203 has 2 main operating modes (Mode 1, Mode 2); each mode is subdivided into 4 modes illustrated in the
table below. The switching between Mode 1 and Mode 2 can be done either through the 3-wire bus
(Chip_config register) or by using the pin SWITCH. The selection depends on the Switch_ext which is a XE1203
register.

5.1. STANDARD SEQUENCE FOR SWITCHING BETWEEN RECEIVER AND TRANSMITTER
The drop-in module DP1203 is able to switch between any configuration by using the 3-wire bus or by using the
pin SWITCH. This section describes the switching sequence from Mode 1 to Mode 2.

6. TYPICAL APPLICATION
The schematic below shows the DP1203 interfaced with a XEMICS’ microcontroller XE88LC06A. In this typical
application, the pad SWITCH is used as an input and the two signals TX and RX are controlled directly by the
microcontroller.
