Device Overview

The FS98O21 is a CMOS 8-bit single chip microcontroller(MCU) with embedded a 2kx16 bits one-time

programmable (OTP) ROM, a 6-channel 14-bit fully differential input analog to digital converter, low noise

amplifier, and 4 x 12 LCD driver.

The FS98O21 is best suited for applications such as electrical scale, meter, and sensor or transducer

measurement application etc.
