RX-2503 DATA SHEET

DESCRIPTION

The RX-2503 module is a Zigbee™ network solution that integrates a 2.4Ghz, IEEE

802.15.4-compliant transceiver with a 16-bit XAP2b microprocessor. It contains integrated
Flash and RAM memory and peripherals of use to designers of Zigbee-based applications.

The transceiver utilized an efficient architecture in which the integrated receiver channel
filtering allows for co-existence with other communication standards in the 2.4Ghz
spectrum such as WiFi and Bluetooth. An optional high performance radio mode (boost
mode) is software selectable to boost dynamic range by a further 3dB. The highly
integrated antenna, power regulator, and Xtal keep the external component count low. The
internal PCB traced antenna and an external U.FL connector port is user selectable. This
maximum the flexibility for the designer to minimize the cost or maximize the system
performance.

The EM250 has 128kB of embedded Flash memory and 5kB of integrated RAM for data
and program storage. The EM250 software stack employs an effective wear-leveling
algorithm in order to optimize the lifetime of the embedded Flash.

To support user-defined application, a number of peripherals such as GPIO, UART, SPI,
I2C, ADC, and general purpose timers are integrated. Also, an integrated voltage regulator,
power-on-reset circuitry, sleep timer, and low-power sleep modes are available. The deep
sleep mode draws less than 2uA, allowing products to achieve long battery life. The
equipped internal watch-dog timer allows the system to be reactivated once the system go
into a dead-lock state. This mechanism makes the system more reliable and available.

Target application for the RX-2503 include:

• Home automation and control

• Building automation and control

• Smart energy monitoring and control

• Tele-healthcare

• Asset tracking
