Development of 16-bit Microcontroller Capable of 5120-dot Display by EPSON
Seiko Epson has successfully developed a ultra-low power 16-bit microcontroller capable of 5120-dot high resolution display, powered by only a coin type battery. The new microcontroller features a 4 grayscale and a built-in 1 MB flash memory.
The newly developed S1C17706 IC features the highest resolution and capacity flash memory amongst the S1C17700 series, a low power consumption 16-bit microcontroller with a dot-matrix LCD driver. The development of this microcontroller was a direct response to growing demand for displays featuring outstanding user interface such as high performance watches or even small potable gaming devices that can be powered by a coin type batteries. The new S1C17706 IC comes with frame memory for display, and LCD driver voltage generator circuit, n-line inversion function for reducing cross-talk as well as partial display function capable of achieving low power consumption through non-display of discretionary common lines. Furthermore, the new S1C17706 IC at its sleep state consumes only 1.2uA, with LCD driver using 9.7 uA. The new S1C17706 IC offers a wide range of peripheral equipment, including A/D converter (10-bit resolution, 8ch, R/F converter (24-bit counter, DC/AC drive switch, and 2ch), Real-time clock as well as various timer circuit and serial interface support.
