8-bit MTP type microcontroller with 12 bit resistive ADC
CSC8122MB

CSC8122MB is an 8-bit microcontroller with MTP and 12 bit resistive ADC. It utilizes the architecture foundation of RISC to enable most of the

The execution time of instructions is one instruction cycle, and only a small number of indirect address access instructions require two instruction cycles.

CSC8122MB is equipped with up to 2KW MTP program memory and 128 bytes data memory, including a 12 bit battery with up to 12 channels

Resistive ADC converter. CSC8122MB provides three hardware counters simultaneously: one is a 16 bit timer, and two 8-bit counters with PWM

Generator. CSC8122MB also supports a hardware comparator
