Patent number: 8988254Abstract: An ultra-low power wakeup circuit device includes a keyboard, a key scan circuit, a storage unit, and a comparator unit. The key scan circuit sequentially outputs scanning signals from the first scan line to N-th scan line for acquiring N key scan data. The key scan circuit performs an XOR operation on the N key scan data to generate a current key scan data. The storage unit is connected to the key scan circuit for receiving the current key scan data and storing the current key scan data as a previous key scan data. The comparator unit is connected to the key scan circuit and the storage unit for comparing the current key scan data with the previous key scan data. When the current key scan data is different from the previous key scan data, the comparator unit generates a wakeup signal.Type: GrantFiled: April 2, 2013Date of Patent: March 24, 2015Assignee: Generalplus Technology Inc.Inventors: Tung-Tsai Liao, Hsin-Chou Lee, Hsin-Lung Lai

Patent number: 8368565Abstract: The invention relates to a power saving method in a sleep mode and a keyboard controller using the same. The method is adapted for a triangular-type scan keyboard controller including a plurality of input/output (I/O) pins. The method includes the steps of: providing a first clock source and a second clock source, wherein the frequency of the second clock source is much lower than the frequency of the first clock source. In a normal mode, a scan pulse is sequentially outputted from the I/O pins according to the frequency of the first clock source. In a sleep mode, the scan pulse is sequentially outputted from the I/O pins according to the frequency of the second clock source. When a specific one of the I/O pins outputs the scan pulse, the other I/O pins are used for detecting.Type: GrantFiled: March 23, 2010Date of Patent: February 5, 2013Assignee: Generalplus Technology Inc.Inventors: Horng-Bin Wang, Hsin Chou Lee

Patent number: 6493778Abstract: An extensible time-sharing bus structure is provided for a microprocessor to read data from or write data to a memory. An address/data bus transfers addresses and data between the microprocessor and the memory in a time sharing manner. The combination of a the logic levels of two control lines is used to determine that the address/data bus is utilized to transfer addresses, to read data or to write data. Thus, the pin number required in the bus interface is reduced, and the memory capacity can be increased flexibly.Type: GrantFiled: December 30, 1999Date of Patent: December 10, 2002Assignee: Sunplus Technology Co., Ltd.Inventors: Hsin Chou Lee, Juang-Jung Long
