Microchip Introduces Low-cost Infrared Protocol Stack Controller

4/21/2003 - Microchip Technology Inc., a leader in providing microcontroller and analog semiconductors, announced a device that provides embedded system designers a very low-cost method of adding Infrared Data Association® (IrDA®)-Standard wireless connectivity to their systems. The MCP2140 is a fixed speed 9600-Baud IrDA-Standard protocol stack controller designed for high-volume applications such as wireless LANs, modems, cell phone peripherals, wireless handheld data collection systems, door locks and fleet management systems among others.

When used with the recommended discrete transceiver implementation, this device enables a complete IrDA-Standard wireless link (protocol handling plus transceiver) to be added to an embedded system while typically consuming less than 100?A of additional current. In comparison, many industry-standard integrated transceivers alone have current consumption values greater than 1.0mA. The MCP2140 employs the same patented technology that embeds the complex IrDA-Standard protocol stack on other Microchip devices, however, the communications speed is lowered and the user-interface is simplified to target low-cost, high-volume embedded applications.

In addition, the MCP2140 has an automatic low-power function that reduces the power consumption when there is no activity on the link. In this low-power mode, the MCP2140 has a typical current consumption of less than 25µA. This low-current consumption enables the addition of IrDA-Standard links to battery applications without taxing overall system power budgets.

“The MCP2140 is the simplest, lowest-cost method for enabling system designers to add IrDA Standard communication capability to their embedded application,” said Keith Pazul, marketing manager for Microchip’s Analog and Interface Products Division. “Focusing on our customers needs, Microchip offers a family of products that enable easy integration of infrared wireless connectivity in embedded devices where size, cost or low power system requirements have historically made it challenging.”

The MCP2140 is an 18-pin PDIP or SOIC package and is priced at $1.50 each in quantities of 1,000. Samples are available via our Web site. Volume production quantities are expected to be available in May.
