Philips Electronics launched its parallel to serial interface I²C bus controller to operate at 400kHz and at low voltages of 3.3V to 2.5V.

The PCA9564 is optimized for interfacing microprocessors, microcontrollers and DSPs with multiple I²C devices or SMBus components.

With the expanded use of I²C as a maintenance and control bus in computing, telecom and networking systems applications, the new chip enables designers to build more flexible, higher performance I²C systems than was previously possible, while the use of 80C51 microcontroller software reduces development time.

The PCA9564 can operate as an I²C master or client and as a transmitter or receiver, while controlling all of the I²C-bus-specific sequences, protocol, arbitration and timing, with no external clock source required. With this device, MCUs and MPUs that do not have an integrated I²C port can interface with I²C or SMBus components, and provide additional ports where multiple I²C bus ports are needed.

"I²C /SMBus has become the de facto standard serial bus for maintenance, control and configuration in most electronic platforms ranging from computing applications to networking and communications," said Pierre-Yves Lesaicherre, general manager, Specialty Logic Product Line, Philips Semiconductors. "With this new PCA9564 I²C bus controller device, we are introducing significant innovation in a mature technology, enabling electronics manufacturers to interface almost any processor or microcontroller with the I²C or SMBus at higher speed and lower voltages than previously possible."

The PCA9564 bus controller is released in 20-lead SO, TSSOP and HVQFN packages.
