The new Half-InchModem is now available for small footprint devices to communicate data with low-power consumption. The self-contained TTL interface voice, data, and fax modem module provides the flexibility to include modem functionality in system products with minimal engineering resources. Typical applications include remote monitoring systems, point-of-service terminals, home security networks, medical devices, and many other similar applications.

The Half-InchModem has a built-in data pump, modem controller, and on-board International DAA. Measuring just 1.0² × 1.0² × 0.3² with a –40° to 85°C operating temperature, the Half-InchModem is controlled by standard AT commands. Its cost-saving line-in-use feature eliminates the need for maintaining a dedicated phone line in many applications.

The Half-InchModem easily integrates online applications into many types of embedded host and remote equipment. It is fully self-contained and requires only a serial TTL interface and phone line access to provide data, fax, and voice operation. The modem’s fast connection provides a simple yet effective approach to data collecting, logging, remote diagnostics, and communications.

 Handset interrupt and connection detection features enable the modem to share a phone line with other equipment, eliminating the cost of a dedicated phone line. Features like DTMF tone detection and generation, voice record, and playback enable the ultimate flexibility for you to easily implement the Half-InchModem’s versatile functionality into your products.

The built-in digital line guard protection automatically detects an overcurrent on tip and ring, preventing the modem from being damaged when accidentally connected to a digital telephone system.

Prices begin at $21 in quantities of 1,000.
