Lenexa, KansasRF supplier AeroComm, Inc. is offering OEMs two ZigBee RF transceivers based on Texas Instruments's recently released IEEE-802.15.4 SoC (system-on-a-chip) and TI's Z-Stack firmware.
For its part, the TI CC2431 SoC combines the performance of TI’s CC2420 RF transceiver with an industry-standard enhanced 8051 microcontroller, 128-kbytes of flash, and 8-kbytes of RAM. That’s key, as no other controller is needed with Aerocomm's ZigBee Your Way modules.
With TI's embedded Z-Stack firmware, the ZB2430 is aimed at secure low-power mesh-network applications. Modules are offered as either Coordinators and Routers (full-function devices) or End-Devices (reduced-function).
Network scan, auto-configuration, dynamic routing, discovery, and security enable the mesh network. These features deliver redundancy, secure multi-communication nodes, and long-range performance. Additionally, the 128-kbytes of on-module flash is ample for larger, more complex application profiles.
Although the 802.15.4 PHY (physical layer) and MAC (media access control layer), and ZigBee stack, are industry standards, AeroComm’s surface-mount products support lots of customization. Graphical utilities and test software assist as you configure and optimize your design.
AeroComm’s ZB2430 ZigBee Your Way spread-spectrum transceivers are power-managed products for power-restricted industrial and commercial applications. Two output-power versions are offered to suit varying applications, and both can operate over the industrial temperature range.
The ZB2430 modules communicate in the 2.4-GHz ISM (industrial , scientific, medical) band. These ZigBee modules are full-featured, too, including battery monitors, temperature sensors, and timers.
ZigBee PHY layer data rates to 250-kbit/s can be implemented. A 3-V RS-232 serial interface supports local data exchanges at rates to 115-kbit/s.
Two Power Levels
A ZB2430 is a roughly 2-mW (max) version, with variable power levels from -20-dBm (0.01-mW) to +2-dBm EIRP (effective isotropic radiated power with a 2-dBi antenna). Its receiver sensitivity is rated at -94-dB (typical), for a 105 bit-error rate.
This module is primarily intended for battery-powered systems. A ZB2430 2-mW version draws about 25-mA at 3.3-V delivering 0-dBm of RF. Current demand drops to less than 300-µA in a Standby mode, dropping to less than a microamp in Sleep mode and just 0.7-µA in a Hibernate mode. It’s priced at about $19 a pop in quantities of 1000.
The ZB2430-100 is a 100-mW unit intended for ZigBee applications needing extended range. Its power can be varied from +10-dBm to the full +20-dBm EIRP.
The -100 version can be powered from a suitable DC source. It draws about 169-mA at 3.3-V delivering +18-dBm. In Receive mode it draws about 27-mA. The ZB2430-100 is priced at about $25 ea/1000.
Aerocomm offers options for these modules, too. Options can include antenna, altered sensitivity specs, interface, different output power ratings, and remote radio configurations, to name a few. Moreover, all of the modules are in surface-mountable packages that convey modular FCC approval. The modules also provide 128-bit AES (Advanced Encryption Standard) encoding and SSP (Security Service Provider).
AeroComm says a number of ZB2430 developer kits are available from both AeroComm and distributor Mouser Electronics.
Each kit includes evaluation boards with multiple configuration options that let you determine the feature set best suited for your application. The eval kits are priced from less than $200 (supporting two radios) to $995 (for five radios and conferring full factory support).
