爱普生发布集成行业领先4,096点阵液晶驱动的Flash 16位单片机

Low Power Consumption Achieved through Single-Chip Solution -


– TOKYO, Japan, February 17, 2009 –

Seiko Epson Corporation ("Epson", TSE: 6724) has developed a low-power-consumption 16-bit microcontroller capable of high-definition LCD display which supports the industry’s largest* display area. Samples of the S1C17705 will begin shipping in April 2009, and volume production, with a monthly output of 500,000 units, is scheduled to commence in August this year.

The S1C17705 contains a dot matrix LCD driver with industry-leading resolution* of 128 SEG x 32 COM, making it ideal for applications requiring high-definition LCD display such as remote controllers, healthcare equipment and sports watches. The product also contains an LCD controller which assists the set-up of two 64 SEG x 32 COM displays, making it possible to achieve the same display as a 64 SEG x 64 COM LCD driver while only using a 32 COM operating current. Moreover, it features a 512 KB high-capacity flash memory that enables it to store large volumes of data such as complex programs and 11 x 12 dot user-defined characters.

By incorporating on a single chip functions previously fulfilled by an LCD driver plus flash microcontroller combination, Epson has been able to reduce the number of components and minimize the mounting footprint. As evidence of Epson’s commitment to the ongoing development of energy-saving technology, a comparison conducted by Epson has shown that the S1C17705 consumes less than one-tenth of the power required by a 2-chip set-up containing a 64 SEG x 64 COM LCD driver and microcontroller.

In addition to LCD displays, the S1C17705 is also ideal for connection to measurement sensors contained in applications. It contains an ultra-low power consumption A/D converter, an R/F converter with 24-bit counter for monitoring temperature and humidity, and various serial interfaces.
