XR18W750 WIRELESS UART CONTROLLER MARCH 2008 REV. 1.0.0 GENERAL DESCRIPTION The XR18W750 is a Wireless UART Controller with a two-wire I2C interface to the XR18W753 RF 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.
