New Epson Application Processor for Electronic Dictionaries and e-Books Combines Advanced Functionality and Low Power Consumption
Singapore May 29 2006: Seiko Epson Corporation ("Epson") has developed an application processor, the S1C33E07, ideally suited to portable devices such as electronic dictionaries and e-books that require high-level data processing and displays.
This product offers a one-chip solution integrating functions required for electronic dictionaries and e-books such as a color LCD control circuit, USB 2.0 device connectivity, and interfaces for electronic media, SDRAM, and NAND flash memory.
The color LCD control circuit is compatible with both STN-type and TFT-type liquid crystal displays and, depending on the hardware, can accommodate accelerators to support features such as Picture in Picture. This enables users of the chip to achieve advanced image capabilities with a minimum of development work.
Power consumption during operation has been reduced by changing the frequency division ratio of the CPU clock and controlling clocks for each block of functions. In addition, Epson's unique low-leak technology minimizes power leakage in sleep mode.
This new application processor offers the high level of functional integration demanded by electronic dictionaries and e-books combined with longer than ever battery life.
Shipment of samples will begin in July 2006, and volume production is scheduled to start in September. The product will be shipped in bare chip, TQFP, and BGA package versions and full-scale production is expected to be 1 million units per month.
Epson will continue to expand its lineup of devices featuring low-power technology in response to customers' diverse needs for such products.
