GENERAL DESCRIPTION

This

document

describes

the

Infrared

Communications Controller (IrCC) function which

is common to a number of SMSC products

including the FDC37C669FR, FDC37C93xFR,

and FDC37C957FR devices. The IrCC consists

of two main architectural blocks:

the ACE

16550A

UART

and

a

Synchronous

Communications Engine (SCE) (Figure 2). Each

block is supported by its own unique register set.

The IrCC UART-driven IrDA SIR and SHARP

ASK modes are backward-compatible with early

SMSC Super I/O and Ultra I/O infrared

implementations. The IrCC SCE supports IrDA

v1.1

.576Mbps,

1.152Mbps,

4Mbps,

and

Consumer IR modes. All of the SCE modes use

DMA. The IrCC offers flexible signal routing and

programmable output control through the Raw

mode interface, General Purpose Data pins and

Output Multiplexer. Chip-level address decoding

is required to access the IrCC register sets.
