The SC8F6790 is a FLASH chip designed by Cmsemicon, featuring 8Kx16Bit Flash, 336B RAM, and an integrated 16MHz RC oscillator. It operates within a voltage range of 1.8V to 5.5V and supports up to 30 GPIOs. The chip features built-in touch key functionality, a watchdog timer (WDT), a high-precision 12-bit ADC, an operational amplifier, two comparators, and integrated modules for LCD and LED driving. It also includes an RGB lighting communication module, PD/QC communication module, USART, I2C, and a 5-channel PWM.
