Fujitsu Microelectronics America has developed a 32-bit CPU and graphics engine on a single chip for applications requiring maximum CPU performance combined with sophisticated 2D and 3D graphics. Built using Fujitsu's 90nm CMOS process technology, the MB86R01 is designed for high-end, high-volume embedded automotive graphics applications, including onboard and mobile navigation systems, graphical dashboard systems, head-up display (HUD) units, rear-seat entertainment, point-of-sale terminals and industrial control panels.

The SoC integrates the 32-bit ARM926EJ-S CPU core with the Fujitsu graphics display controller.

The ARM926EJ-S is a fully synthesisable processor with a Jazelle (Java Acceleration) technology-enhanced 32-bit RISC CPU, 16KB instruction cache, 16KB data cache, 16KB ITCM, 16KB DTCM and memory management unit. The CPU runs all major operating systems and state-of-the-art middleware, including Microsoft Windows CE, QNX, Wind River VxWorks, Linux and Itron.

The graphics processor IC provides requirements for embedded graphics applications?such as in-car infotainment systems?via a rendering engine for 2D/3D graphic acceleration functions, a geometry processor supporting floating-point transformations for smooth graphics animation and a dual-display capability (2 x RGB digital output), which allows different content to be shown on two connected screens.

The MB86R01 incorporates an ETM9 (medium) and JTAG ICE interface, eight-channel DMA and 32-bit timers. Core frequency is 320MHz (generated by the on-chip PLL). Onboard peripherals include a unified DDR2 memory supporting 320Mbps (up to 128MB), a parallel flash/SRAM host interface with decryption engine, parallel ATA, SD-Card, CAN interface, Media LB and USB 2.0 (host and function). There is also a DAC and ADC, along with I ?C and I ?S interfaces, PWM, SPI, UART, GPIO and an external interrupt.

Other features include bit-blt and texture mapping units (up to 4,096 x 4,096), alpha bit-blt and ROP2 functions, and six layers of overlay display. Dual-digital video-input formats include YUV, RGB and ITU656. The MB86R01 supports built-in alpha blending, anti-aliasing and chroma-keying. Display resolutions range from 320 by 240 up to 1,024 by 768. Packaged in a 484-pin BGA, the device requires a supply voltage of 3.3V (I/O), 1.8V (DDR2), 1.2V (internal) and is designed to operate over a temperature range of -40?C to 85?C.

Samples are now available, with pricing at Rs.1,648.52 each in sample quantities.
