Embedded DRAM intelligent buffer ICs

Extending embedded DRAM (eDRAM) technology to support designers of mobile phones, music players and other portable devices, NEC Electronics has introduced two SoC (System-on-Chip) devices that integrate 16 Mbits (uPD60800) and 30 Mbits (uPD60801) of eDRAM memory with graphics-processing logic and a high-speed MIPI-DSI (Mobile Industry Processor Interface—Display Serial Interface) graphics-data connection to the host processor. The intelligent buffer ICs (integrated circuits) enable low power consumption with high resolution and convenient display-panel configurations. By inserting the new devices between the digital-baseband LSI or application processor and the LCD-driver IC, designers can implement new power- and cost-saving strategies while supporting Quarter HD- and WSVGAresolution displays. The uPD60801 integrates AGCPS-II (Auto Gamma Control & Power Saving) functionality, the backlight-control technology that NEC Electronics developed. The AGCPS-II automatically recognizes image data and adjusts the backlight brightness accordingly, thereby contributing to low power consumption combined with high image quality.
