FS9932
General Description
The FS9932 is a high performance, low cost CMOS 8-bit single chip microcontroller with an embedded 2kx16 bit ROM, a 6-channel 14-bit fully differential input analog to digital converter, a low noise amplifier, and a 4 x 12 LCD driver.
The FS9932 is best suited for applications such as low cost body scale, barometer, hygrometer, etc.
