Toshiba America Electronic Components Inc. (TAEC) announced the availability of the TX4961XBG-240, a 64bit RISC processor with integrated graphics and display controller designed for applications that combine general-purpose computing with real-time graphics displays, including driver information systems, car infotainment systems and car navigation systems. It integrates a TX49/H3 64bit MIPS-based RISC CPU with a display controller and hardware graphics accelerators in a single SoC.

"The TX4961XBG-240 is Toshiba's first TX49-based product to combine a 64bit CPU and a graphics display controller with a 2D hardware graphics accelerator and video frame grabber. By offloading the graphics, display and video functions to dedicated hardware, the full power of the processor is available for application-specific processing," said Shardul Kazi, vice president of the ASSP business unit at TAEC. "The TX4961XBG-240 is optimized for automotive dashboard displays that combine an instrumentation display with navigation information and video. It is also well-suited for numerous other applications that require the high-quality display of real-time data."

The product features an on-board DDR SDRAM controller, unified memory architecture and multiple on-chip buses. It also incorporates a video frame grabber, AC-Link and I2C controllers, various timers and high-speed serial ports, 10bit ADC, 16bit pulse-width modulation outputs, GPIO ports, and CANbus and Media-LB interfaces with DMA, interrupt, external bus and NAND flash controllers.

Features of the product include the following: core operates at 240MHz; integrates 16KB instruction cache and 16KB data cache; operates in automotive/industrial temperature range of -40C to 85C ambient temperature; Features 24bit true color pixels with 8bit alpha blending; incorporates a five-layer graphics architecture; blitting engine that can perform font expansion and scaling; Housed in a 456-pin PBGA with a 1mm ball pitch.

Samples are currently available, and volume production is scheduled to begin in the fourth quarter of 2006. The device is priced at $40 each in 10,000-piece quantities. The RBTX4961 reference board is also available.
