CAMAS, Wash.--Sharp Electronics Corp.'s U.S. division here today announced it has begun shipping beta samples of a new 200-MHz system-on-chip device, based on an ARM922T RISC core, for wireless handheld games, smart phones, pocket PCs, home entertainment controllers, industrial "Web tables," and point-of-sales terminals.
Sharp Microelectronics of the Americas said the LH7A400 is the second family of highly integrated SoC chips to be shipped from the Camas facility since the company set up its North American design center for micrcontrollers and system-on-chip designs earlier this year (see Feb. 12 story).
"The LH7A400 is targeted at today's Internet and multimedia-centric applications," said Terry Thomas, director of marketing for microcontroller and SoC products at the U.S. subsidiary. "Offering the performance of 200-MHz with high integration and functionality coupled with low power consumption and world-class development tools, the LH7A400 allows designers to lower system costs, shorten development cycles and bring their product to market sooner."
The chip integrates a 200-MHz RISC processor core from ARM Ltd., 8 kilobytes of instruction cache, 8 Kbytes of data cache, a 10-channel direct memory access (DMA) engine, and memory management unit (MMU). It is capable of processing 220 million instructions per second (MIPS), according to Sharp. An 80-kilobyte on-chip frame buffer allows a 160-by-240 16-bit image to reside on the device, which reduces power consumption and optimizing system bandwidth, said the company.
Sharp said it will offer embedded Linux operating system support through a new partnership with Lineo Inc. of Lindon, Utah. Additional support for other operating systems--such as Microsoft Corp.'s Windows CE 3.0 and CE.NET--will also be made available, Sharp said.
The LH7A400 device will be priced under $24 each in quantities of 10,000. Production of the chip is scheduled to begin in the second quarter of 2002.
