SOC(Shenzhen SinOne Microelectronics) SC92F7422M20U

The SC92F742X series is an enhanced high-speed 1T 8051-core industrial-grade Flash microcontroller with an instruction set fully compatible with the traditional 8051 product family. It integrates 16 Kbytes Flash ROM, 256 bytes + 256 bytes SRAM, 128 bytes EEPROM, up to 26 GPIOs, 14 IOs with external interrupt capability, three 16-bit timers, eleven 12-bit high-precision ADC channels, six independent 8-bit PWM channels, IO drive level control (P0 and P2 ports), an internal ±1% high-precision high-frequency 16/8/4/1.33 MHz oscillator, a ±4% accuracy low-frequency 128K oscillator, external crystal oscillator support, SSI communication interface, and other resources. To enhance reliability and simplify customer circuitry, it also integrates high-reliability circuits including a 4-level selectable voltage LVR, 2.4V reference ADC voltage, and WDT. With excellent EMI immunity, it is well suited for a wide range of applications including IoT control, large and small smart appliances, smart home systems, chargers, power supplies, aerial models, walkie-talkies, wireless communications, gaming consoles, and other industrial control and consumer applications.
