DP1203 868 / 915MHz RF Modules (Shielding removed for clarity) DP1203 – C868 / C915 868 and 915MHz Drop-In RF Transceiver Modules Small Form Factor and Direct Digital Interface Modules GENERAL DESCRIPTION KEY PRODUCT FEATURES The DP1203 is a 30mm x 18mm shielded radio transceiver module available for use in either the 868-870MHz or the 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. 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-topoint communication to more complex multipoint process control functions. The module is suitable for surface mount reflow assembly. Semtech provides basic firmware routines controlling the module and typical applications. for • Instant RF – solder and use! • No RF knowledge required • 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 APPLICATIONS • DEVICE OPTIONS Home automation and access control • Process and building control • Cable replacement Rev 1 April 2006 Part Number Description Packing Method DP1203C868 DP1203C915 868-870MHz 902-928MHz Tape&Reel Tape&Reel Pinpacka ge Board Board www.semtech.com 1 DP1203 868 / 915MHz RF Modules Table of Contents 1 Pin Description ........................................................................................................................................... 3 2 2.1 2.2 Electrical Characteristics .......................................................................................................................... 4 Absolute maximum operating ranges........................................................................................................... 4 Specifications ............................................................................................................................................... 5 3 Functional Description .............................................................................................................................. 6 4 Serial Control Interface.............................................................................................................................. 7 5 5.1 Operating Modes ........................................................................................................................................ 8 Standard sequence for switching between receiver and transmitter ........................................................... 9 6 Typical Application .................................................................................................................................. 10 7 Mechanical Dimension............................................................................................................................. 11 8 Packaging Information............................................................................................................................. 12 © Semtech 2006 www.semtech.com 2 DP1203 868 / 915MHz RF Modules PIN DESCRIPTION PIN 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 NAME GND RF GND VDDP VDDA GND VDD /EN SWITCH GND GND SO SI SCK CLKOUT DCLK DATA DATAIN PATTERN RX TX I/O IN IN/OUT IN IN IN/OUT IN IN OUT IN IN OUT OUT IN/OUT IN OUT IN IN DESCRIPTION Ground RF input / output terminal Ground VDD for power amplifier VDD for analog blocks Ground Supply voltage 3-wire interface communication enable signal Receiver or transmitter mode selection Ground Ground 3-wire serial data interface: Data Out 3-wire serial data interface: Data In 3-wire serial data interface: Data Clock Programmable reference clock output Receiver data clock Transmitter data input or receiver data output Transmitter data input Receiver pattern recognition output Antenna switch RX Select Antenna switch TX select © Semtech 2006 www.semtech.com 3 DP1203 868 / 915MHz RF Modules ELECTRICAL CHARACTERISTICS 1.1 ABSOLUTE MAXIMUM OPERATING RANGES Description Supply voltage Operating temperature Storage temperature Soldering temperature (max 15 sec) Min 2.4 -40 -55 Max 3.6 +85 125 260 Unit V o C o C o C CAUTION: ESD sensitive device.

The module is based on the RF transceiver circuit from SEMTECH, the XE1203. For more information on the XE1203, please refer to the Semtech web site. 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.

The output signal, SO, is provided by the DP1203 in opposition to the SCK and SI which need 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.

The switching between Mode1 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.
