Sharp's new LH7A400 is a 200-MHz System-on-Chip (SoC) with ARM922T core is intended to support a range of applications that include wireless handheld gaming devices, smartphones, pocket PCs, home entertainment controllers, industrial web-tablets, and point-of-sale devices. The LH7A400 integrates a 200MHz ARM922T core, 8 kB instruction cache, 8 kB data cache, MMU, and write-back buffer, and provides a processing speed of about 220 million instructions per second (MIPS). The 80 kB of on-chip frame buffer allows a 160x240 16-bit image to reside on-chip, reducing power consumption and optimizing system bandwidth. System bandwidth is also optimized by the on-chip 10-channel DMA engine. The LH7A400 also includes a programmable LCD controller that supports up to 1024x768 resolution, up to 64,000 colors and 15 gray shades with a direct interface to STN, Color STN, and TFT. For storage, the LH7A400 provides glue-less interface to SRAM/SDRAM/Flash devices, MMC, PCMCIA/CF, and Smart Cards. For communication, the LH7A400 provides serial as well as parallel interfaces (USB, UARTs, Synchronous Interfaces, and AC'97 Codec Interface). The LH7A400 also has a Watchdog timer to protect the overall system. Sharp's recent announcement of a strategic relationship with Lineo for embedded Linux support will soon be followed with additional support for operating systems like Windows CE 3.0 and Windows CE .NET operating systems. The LH7A400 will be priced under $24 in 10,000 units with production scheduled for Q2, 2002.
