Epson Develops Application Processor Offering a One-Chip Solution for Integrating Display and Interface Functions

- Provides a 10% Increase in Operating Frequency Compared to Conventional Products

/noticias.info/ Seiko Epson Corporation ("Epson") has developed the S1C33L17, an application processor that is ideally suited to analog input large-screen full-graphic LCD displays and various interfaces, as well as to portable devices such as electronic dictionaries, which require high-level data processing and displays. This application processor is also ideal for operation panels and display system devices, which require such functions as display, and operation by means of touch-panel or key-input.

This product offers a one-chip solution integrating functions such as color LCD control circuit, USB 2.0 device connectivity, AD converter, and interfaces for electronic media, SDRAM, and NAND flash memory, that are required for electronic dictionaries, operation panels, and display system devices. Compared with conventional products, the S1C33L17 enables even faster processing capabilities by providing a 10% increase in operating frequency, and its color LCD control circuit boosts its compatibility with TFT-type liquid crystal displays from 12-bit color (4,000 colors) to 16-bit color (64,000 colors).


The I2S(*) external interface has made it possible to select 16- or 24-bit resolution for the input/output channel by boosting compatibility from supporting only a 16-bit input channel to supporting a 16/24-bit input/output channel. Furthermore, as an output mode, it supports stereo, monaural, and mute outputs.

Depending on the hardware, this product can accommodate accelerators to support features such as Picture in Picture, thereby enabling users of the chip to achieve advanced image capabilities with a minimum of development work. Moreover, 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, employing Epson's unique low-leak technology makes it possible to minimize power leakage in sleep mode. This new application processor offers both the high level of functional integration and long battery life demanded by electronic dictionaries, operation panels, and display system devices. notas_de_prensa_archivo
