Texas Instruments Expands Presence in the Infrared Controller Market with Complete High-Speed Solution

Devices Expand TI's Technology Leadership in the Mixed-Signal/Analog Market

The infrared controller, designated the TIR2000, is an interface between the ISA bus and an infrared transceiver that encodes and decodes the information so that it conforms to the appropriate standard and can be understood and communicated by multiple systems. The TIR2000 also converts the data into a format that can be transmitted by the infrared transceiver. The TIR2000 has a smaller pin count than any other 4Mbps IrDA solution currently on the market, which saves board space.

The infrared transceiver, designated the TSLM1100, is a multi-die module that includes a pin photodiode, a two-path receiver with LED driver, and an 870nm LED. The TSLM1100 interfaces directly with an IrDA controller and operates at data rates from 2400 bps to 4 Mbps. The TSLM1100 is built using TIs CMOS processing, enabling a high level of integration for better reliability.

Features/Benefits

Supports IrDA 1.0 and 1.1 (TIR2000 and TSLM1100)	Allows communication with other products that follow this standard.
Selectable 16 or 64-byte FIFO (TIR2000)	Increases system efficiency and speed by storing more information before having to send an interrupt request to the host and increasing packet size in DMA mode.
Supports 11 IRQ options and 3 direct memory access (DMA) configurations (TIR2000)	Offers designers the flexibility to use either Interrupt or DMA mode for data transfer, and gives several options of interrupt lines or DMA channels to use in each mode.
Power management support and 3.3V or 5V operation(TIR2000)	Conserves power in systems which run on batteries or have power-saving concerns.
64-pin thin quad flat pack (TQFP) package (TIR2000)	Saves board space; this is the smallest package currently on the market for a 4Mbsp infrared controller solution.
Compatible to current market solutions (TSLM1100)	Gives customers other design options.
CMOS design (TSLM1100)	Provides higher reliability due to high level of integration.

End Equipment Applications

Applications for the TIR2000 and TSLM1100 IrDA solution include:

• PCs
• Notebook computers
• Printers
• Personal digital assistants (PDAs)
• Telephones
• Digital cameras
• LAN
• Handheld devices

Availability, Packaging and Pricing

The TIR2000 and TSLM1100 are now available from TI and its authorized distributors. The TIR2000 is available in a 64-pin TQFP with a suggested price of $6.42 in quantities of 1,000. The TSLM1100 has a suggested price of $5.55 in quantities of 1,000. TI also has a slow-speed IrDA controller, the TIR1000, which is available in an 8-pin thin shrink-small outline package (TSSOP) with a suggested price of $1.15 in quantities of 1,000.
