GIT Japan Uses CAST 8051 in AIST’s MEMS-EFS Electrostatic Sensor

Woodcliff Lake, NJ and Rittoh, Japan, March 19, 2014 ---- GIT Japan has used an 8051 IP core licensed from CAST, Inc. in a custom chip GIT developed for Japan’s National Institute of Advanced Industrial Science and Technology (AIST).

The 8051-managed chip implements AIST’s research on applying Micro-Electro-Mechanical Systems Electrostatic Field Sensors (MEMS-EFS) to detecting and measuring static charges. The system employs self-sensitive piezoelectric microcantilevers and detects and processes the charge produced by their vibration to yield an output voltage proportional to the intensity of the detected electro-static field.

 “CAST’s efficient, easy-to-use 8051 core was an excellent solution for our challenge of building AIST’s innovative electrostatic field sensor system,” said Yoshinori Nakagawa, design engineer for GIT Japan.

AIST’s published research project was supported by the Funding Program for World-Leading Innovative R&D on Science and Technology (FIRST Program), initiated by Japan’s Council for Science and Technology Policy (CSTP). Learn more about AIST at
