SC51F2832 is 8-bit MCU, integrating 10-bit ADC and LCD driver.It bases on SC51 core and embeds 32K-byte FLASH and 2K-byte RAM. It integrates PLL(only for 48-pin package) to generate 2/4/8/12MHz main clock based on low clock 32768Hz, reducing the system cost and avoiding high frequency oscillation interference during noise sensitivity application. It is suitable for low-noise applications.
