Product Name
 
SC51P5704
 
 
Function Description
 
8-BIT MCU INTEGRATING 10-BIT ADC
 
 
Application
   
 
Product Description
 
SC51P5704 is 8-bit MCU integrating 10-bit ADC. It bases on SC51 core and embeds 4K-byte OTP and 256-byte RAM. It integrates high accuracy RC oscillator, operational amplifier and comparator, also 4-channel 12-bit PWM for brushless motor, and internal PLL provides clock source (up to 32MHz) to PWM. It is suitable for single-phase brushless motor, mobile power supply and small home appliance control.
