Epson has debuted the world’s smallest assisted GPS chip, the Infineon XPOSYS. Measuring in at a minuscule 2.8 x 2.9 millimeters, the Infineon XPOSYS is 25 percent smaller than any other assisted GPS chip, while cutting energy consumption in half according to Epson. The chip is also more sensitive than previous Infineon chips, allowing for an accurate location fix indoors. The XPOSYS is scheduled for mass production in late 2009, so expect it to ship in mobile devices next year.
The Japanese giant Hitachi has developed the world's smallest and thinnest Radio Frequency Identification (RFID) chip. Measuring only 0.15 x 0.15 millimeters in size and 7.5 micrometers thick, the wireless chip is a smaller version of the previous record holder - Hitachi's 0.4 x 0.4 mm "Micro-Chip". The company used semiconductor miniaturization and electron beam technology to write data on the chip substrates to achieve this decrease in size. The new chips have a wide range of potential applications from military to transportation, logistics and even consumer electronics.
