64bit processor is single solution for auto displays
01 August 2007
This Capricorn-A RISC-based SoC processor is the latest in the Toshiba Electronics Europe family and claims the highest level of integration for automotive displays (www.toshiba-components.com).
The QFP package drives and manages the small (three to five inch) TFT 1/2VGA/VGA displays in instrument clusters in cars. The SoC integrates the 64bit processor, a MIPS-based TX49/L4 64bit, a 120MHz CPU core with a graphical display controller and dedicated accelerator functions, and on-board peripherals and interfaces. The graphics accelerators have several handling functions to enhance the display output of changing graphics. A frame grabber can work with a variety of input data formats for capture and processing video images supporting applications such as rear view monitoring. It has dedicated hardware for cluster graphics and can deliver up to 32bit RGBA colours. SoC reduces component count. There is also no need for external RAM, as an embedded DRAM is included to reduce the component count and board space as well as minimise the EMI shielding requirement through a reduction in external PCB tracks needed for operation. Toshiba also claims that it reduces dependency on availability and costs of external RAM.
Toshiba has also announced the TLWK1100B white LED. At typical luminous intensity levels of 1500mcd from a drive current of just 20mA, it doubles previous devices in the same form factor. It is supplied in a PLCC2 surface mount package, measuring 3.2mm x 2.9mm x 1.9mm for use in panel indication, LCD backlighting in automotive applications.
