National Semiconductor's Bluetooth wireless personal area network (WPAN) module, the LMX9814, has achieved v1.1 certification. The LMX9814 is claimed to be one of the industry's smallest complete Bluetooth solutions, measuring 10,1 x 14 x 1,9 mm. It is based on National's LMX5250 CMOS radio and LMX5100 baseband processor. In addition to full Bluetooth (V1.1) capabilities, it integrates Flash memory for customer firmware upgrades, front end filtering, receive/transmit switching, localised supply voltage decoupling, and USB and UART host control interfaces. LMX9814 employs an external antenna and can accept a wide range of system clocks from 10 to 26 MHz. It supports Bluetooth Class 2/3 transmit power levels, which specify a nominal transmit power of up to +4 dBm.

As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
