GENERAL DESCRIPTION

The XR18W750 is a Wireless UART Controller with a

two-wire I

transceiver to complete Exar’s Wireless UART

chipset solution. The XR18W750 supports both the

parallel and serial interfaces to any host system thus

providing flexibility for system designers to select

their interface option.

The XR18W750 includes an embedded 8051

microprocessor which provides the power to process

the protocol framing for data transmission and to

handle error processing. Internally, the XR18W750

has a 32KB system memory for loading the firmware

from an external EEPROM and for data processing.

The XR18W750 also includes a 128-bit AES engine

for data encoding and decoding.

The XR18W750 is available in a 48-pin QFN

package.
