Title: Seiichi Yamazaki: Innovator in Microcomputer Technology
Introduction
Seiichi Yamazaki is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of microcomputer technology, holding a total of 6 patents. His innovative designs have paved the way for advancements in electronic devices.
Latest Patents
One of his latest patents is a microcomputer equipped with a built-in temperature sensor. In this design, diodes are incorporated as temperature sensors in a pair of circuit blocks, placed in opposite polarity connection to each other. When detecting the temperature of the microcomputer, a constant current If is supplied to the diodes through terminals commonly connected to both diodes. The voltage Vf generated at each diode is read through terminals located at more adjacent nodes to the diode compared to the terminals.
Another significant patent is a counting circuit with rewritable non-volatile memory and a counting method. This frequency counter includes a binary counter section that counts up frequency data and an EEPROM counter section that contains frequency data. During frequency count processing, frequency data from the EEPROM is loaded into the binary counter, which executes a count up by a specified frequency on the loaded data. The counted frequency data is then written back into the EEPROM, updating its contents. This process reduces the number of times the EEPROM is rewritten, enhancing its longevity.
