FS98O02

General Description

The FS98O02 is a high performance, low cost 8-bit MCU with 2k program EPROM, 128-byte data RAM, one 14-bit ADC, 12-bit GIO, and 4 °— 12 LCD driver.
With a few external passive components such as resistors and capacitors, the FS98O02 can be easily implemented to form a simple portable tire gauge, voltage panel meter, or manual range DMM, etc. Especially, FS98O02°¶s EPROM could be written by program instruction, so users can write table or calibration data in the unused EPROM address more than one time.
