LTC4316 is the I2C Babelfish

The LTC4316 is something special. It’s an I²C address translator that changes the address of a device that would otherwise conflict with another on the same I²C bus. Not a hack? Not so fast. Exactly how this chip does this trick is clever enough that I couldn’t resist giving it the post it rightfully deserves.

On-the-Fly Translation

What’s so special? This chip translates the address on-the-fly, making it transparent to the I²C protocol. Up until this point, our best bet for resolving address collisions was to put the clashing chip on a separate I²C bus that could be selectively enabled …read more

Qualcomm Buys NXP In Largest Ever Semiconductor Deal

Reuters has reported that Qualcomm will purchase NXP for $38 Billion in the largest semiconductor deal ever.

This deal was rumored last month in a deal worth about $30 Billion. Qualcomm’s name should be familiar to all Hackaday readers – they have an immense portfolio of mobile processors, automotive chips, and a ton of connectivity solutions for WiFi, Bluetooth, and every other bit of the EM spectrum. NXP should also be familiar for their hundreds of ARM devices, automotive devices, and Freescale’s entire portfolio.

The deal for $38 Billion is just a bit larger than the previous largest semiconductor deal, …read more
