Control module is ready for ZigBee

A new ultraminiature ZigBee-ready module offers almost any electronic system in a commercial, industrial or home environment a simple and low cost wireless control capability.

Spectre has launched an ultraminiature ZigBee-ready module, less than a quarter of the size of a credit card, specifically designed to offer almost any electronic system in a commercial, industrial or home environment a simple and low cost wireless control capability.

With an area of just 37 x 18.4mm, the Telegesis ETRX1 ZigBee ready module is an ultra-low-power module, that is easy to interface to the host application, and easy to set up via a wireless connection.

Based on Ember silicon, the ETRX1 comes complete with a IEEE802.15.4 compliant ready protocol stack, and is offered with a choice of an integrated antenna, or a Hirose antenna connector.

Features include the proprietary Ember "boot-loader" capable of boot-loading over the air, or via an RS232 port.

Physical connection to the host device can be via surface mounting pads on the base of the module, or a 1.27mm pitch board-board connector.

Drawing just 30mA in full operation, 15uA on standby, the module operates from a 3V supply.

Interfacing features include a UART for easy communication, and eight general purpose I/O lines including an analogue line.

Control is via an AT-command set, or alternatively the module can be supplied blank for the customers own software.

At power up, the last configuration is loaded from the S-registers, which can eliminate the need for an additional host controller.
