FS98O24 (OTP Type)
General Description
The FS98O24 is an 8-bit RISC-like microcontroller with 4k x 16 bits OTP program memory, auto range DMM function network, one 14-bit fully differential input analog to digital converter, two low noise amplifiers, and 4 COM x 20 SEG LCD driver.
The FS98O24 is best suitable for applications such as 3 3/4 DMM and other measurement instrument products.
