Embedded modem eases data communications

By Warren Webb -- EDN, 9/8/2005

Targeting applications in remote monitoring systems, point-of-sale terminals, home security networks, medical devices, and backup-communication systems, Radicom Research recently announced a latest low-power, low-cost modem. Standard AT commands control the Half-Inch Modem, which measures just 1×1×0.3 in. with a –40 to +85°C operating temperature. The modem includes a built-in data pump, modem controller, and onboard international DAA (data-access arrangement). With power consumption as low as 18 mA in sleep mode, the modem delivers data rates as high as 56 kbps. Alex Tsau, vice president of operations at Radicom, says, “The Half-Inch Modem simplifies the design process for data-communications functions, allowing designers to add connectivity to their applications in a very small space”.

The self-contained modem requires only a serial TTL interface and phone-line access to provide data, fax, and voice operation. Handset-interrupt and connection-detection features allow the modem to share a phone line with other equipment, eliminating the cost of a dedicated line. The Half-Inch Modem is available now, and prices begin at $21 (1000).
