12/22/2003 - Royal Philips Electronics (NYSE: PHG, AEX: PHI) introduced a Local Interconnect Network (LIN) I/O slave expander, designed to help manufacturers build cost-effective, fail-safe LIN networks in the car. The UJA1023 device supports up to eight identical LIN I/O slave nodes on a single LIN-bus (and even thirty with additional wiring effort), allowing design engineers to simplify the design process and reduce component count for IVNs.
Already, LIN provides a low cost IVN solution for a number of body control applications, enabling drivers to easily activate power windows or switch-on the heated seating in a car. Philips’ LIN I/O slave expander can be used to control up to eight LIN applications within the vehicle without the need for a microcontroller or other external components. These applications include backlighting LEDs, buttons, switches, sensors and power FETs for driving lamps or motors. This will make it simple and even more cost-effective for designers to build LIN networks and design engineers to reduce interconnection costs by at least 10%.
“As market leader in IVN semiconductors, Philips has developed the UJA1023 in response to customer demand for increasingly cost-effective, fail-safe and compact IVN solutions,” said Jacob van der Pol, CAN/LIN segment manager at Philips Semiconductors. “In addition, the UJA1023 is in line with the increasing use of LIN in the car, as it offers a versatile single-chip solution enabling the controlling of multiple LIN applications with just a single device.”
The UJA1023 features an integrated LIN transceiver, an on-chip oscillator, eight configurable I/O’s and automatic bit rate synchronization to any bit rate between 1kbit/s and 20kbit/s. The outputs of the device can be configured as high and/or low side driver, cyclic or PWM driver. The inputs feature an eight channel multiplexed 8-bit AD-converter, a configurable edge capture function and have wake-up capability.
Samples of the UJA1023 are now available with mass production scheduled to begin Q3 2004.
