The IrDA 1.x low and high-speed communication modes support all speeds up to 16 Mb/s (VFIR). All speeds can use Direct Memory Access. The same drivers are used for all speeds for receiving and transmitting, simplifying driver programming and speed upgrades. Typical applications include data transfer in notebook computers, desktops computers, printers, access-points, digital cameras and peer-peer or client-server network environments. The Host Interface module connects to an ISA bus or PCMCIA bus. It contains the bus interface logic, system configuration registers, power management circuitry, and local DMA control functions. The IRC1802 supports two modes of block data transfer: Host DMA and Shared Memory Buffer. In Host DMA mode, data is transferred using the host system’s DMA controller. In Shared Memory mode, data is first buffered in local RAM, then read by the host during receive-mode or shifted out to the infrared link during transmitmode. s Shared Memory and Host DMA modes Shared Memory mode is a Local DMA mode with 32 Kbytes SRAM locally. In this mode, both the controller and host have access to a shared block of memory to which data can be read or written. During packet transmitting or receiving there is no data transfer on the system bus. For packet sending, the host copies the packet to the Tx buffer of shared memory, initializes the Transmit Request and waits for the End of Transmit, EOTR, condition to generate an interrupt. For packet receiving, the host waits for the End of Receive, EOR, interrupt condition and copies packets received from the Rx buffer of shared memory. The programming is simple and the operation is fast. s Burst packet transmission and reception support for all data rates Burst data transfer consisting of multiple IrDA frames are accomplished by adding control headers to the desired outgoing data frames and arranging them sequentially in the transmit buffer of the host’s or local shared memory. The Tx and Rx Frame Control Modules control transmit and receive functions. The 32 Kbytes shared memory can keep seven IrDA frames with size of 2048 bytes. s Direct Interface to both Legacy and Digital Serial Interface (SIF) Transceivers The Serial Interface (SIF) module allows the controller to interface directly to Infineon’s IRM1600 transceiver. This transceiver supports new features like speed mode select (VFIR), programmable modulation setting, LED power control, receiver sensitivity and power management.

The Infrared Core module controls all infrared communication functions. It is divided into four subsystems: SIR, MIR, FIR and Very Fast Infrared (VFIR). Each subsystem consists of a controller and a modem. The SIR subsystem improves on the popular 16550 UART scheme by combining a high performance DMA asynchronous receiver-transmitter with the hardware Link Access Protocol (IrLAP) for a complete hardware SIR packet transfer.
