GENERAL DESCRIPTION
The CAM35C44 with IrDA v1.1 (4Mbps) and
Consumer IR support incorporates SMSC’s
advanced Infrared Communications Controller
(IrCC 2.0), a 16C550A-compatible UART,
Multiple Host Interface options, flexible Address
Decoding and up to five General Purpose I/Os.
The CAM35C44 also features sophisticated
power control circuitry to support multiple power
down modes, an on-chip 24MHz crystal
oscillator, and
12mA
host bus drivers.
The CAM35C44 is particularly suited for 3.3v
battery-powered systems.
