SOC(Shenzhen SinOne Microelectronics) SC92F8412X20U

The SC92F841X is a series of enhanced high-speed 1T 8051-core industrial-grade Flash microcontrollers with integrated capacitive touch key functionality, fully instruction-compatible with the traditional 8051 product family. It features a built-in 23-channel low-power, high-sensitivity capacitive touch circuit, which can optionally operate in STOP Mode. Also integrated are 16 Kbytes Flash ROM, 1 Kbytes SRAM, 128 bytes EEPROM, up to 26 GP I/Os, 13 IOs with external interrupt capability, three 16-bit timers, 11-channel 12-bit high-precision ADC, 6-channel independent 10-bit PWM, internal ±1% high-precision high-frequency 24/12/6/2 MHz oscillator and low-frequency 32K oscillator, external crystal oscillator support, one UART, and one SSI multi-function port (UART/SPI/TWI selectable). To enhance reliability and simplify customer circuitry, the device also integrates high-reliability features such as a 4-level selectable voltage LVR and a 2.4V reference voltage for ADC. With excellent anti-interference performance and superior touch key performance, the SC92F841X is ideally suited for touch key and main control applications across a wide range of use cases, including large and small smart appliances, smart home, IoT, wireless communications, gaming consoles, and other industrial control and consumer applications.
