Product Information

www.DataSheet4U.com XE24S500 December 2006 Xecom XE24S500 the Smallest, Complete 2.4 GHZ FHSS Transceiver Description The Xecom XE24S500 is a miniature 2.4 GHz Spread Spectrum transceiver. It includes all RF hardware and a micro-controller to manage the communications link. The micro-controller manages all communications task including configuration, data packaging, and Frequency Hopping. The result is a complete wireless data communications solution. The XE24S500 package is unique because of its size (less than 1.4 square inches), its leadless surface-mount design, and the availability of an on-board chip antenna. No competitive products can offer a solution as flexible, convenient, and easy to integrate, There are two XE24S500 models; the XE24S500C with the on-board chip antenna and the XE24S500D with dipole antenna connector. The dipole antenna improves range while the chip antenna lowers system cost and simplifies integration. Development Kits are available for each version. A pin-compatible, lower power variant is also available, the XE24S100, for applications with lesser range requirements.

The #P command selects the transceiver operating mode when it is not actively transmitting or receiving data. Below are descriptions of all of the available selections. IDLE: In Idle Mode all XE24S500 circuits are powered and available for immediate action. This includes the RF receiver which actively monitors the air for an incoming communications request. SLEEP: In Sleep Mode all XE24S500 circuits are powered-down to minimize power consumption. The XE24S500 cannot accept commands or respond to incoming RF communications requests from Sleep mode. Any input on TXD will wake the transceiver and return it to the previous mode, either the Idle or Power-Down Mode Current draw in Sleep Mode is less than 50 microamps. POWER-DOWN: In Power-Down Mode all RF circuitry is shut down but the communications controller remains active to accept AT commands. The XE24S500 cannot respond to incoming RF communications requests. If a transmit RF or receive RF command is received, the XE24S500 can activate the RF section in under 200 microseconds. Current draw in Power-Down Mode is less than 2 milliamps. RF MONITOR MODE: RF Monitor Mode holds the transceiver in power down mode for an interval set by Register S110. The transcevier then activates, turns on its receiver, and checks the air for incoming messages. If no messages are detected within 200 milliseconds, the transceiver returns to power down mode. If carrier is detected, the transceiver completes the transaction before returning to power down mode. S110 selects an ...
