SOC(Shenzhen SinOne Microelectronics) SC92F7250M08U

The SC92F725X series is an enhanced 1T 8051-core industrial-grade Flash microcontroller with an instruction set fully compatible with the traditional 8051 product family. It integrates 4 Kbytes Flash ROM, 256 bytes SRAM, 128 bytes EEPROM, up to 18 GPIOs, 6 IOs with external interrupt capability, 3 16-bit timers, 9-channel 12-bit high-precision ADC, 6-channel independent 8-bit PWM, IO drive level control (P0 and P2 ports), internal 1% high-precision high-frequency 24/12/6/2MHz oscillator and ±4% accuracy low-frequency 128kHz oscillator, UART and other communication interfaces. It also integrates high-reliability circuits including 4-level selectable voltage LVR, 2.4V reference ADC voltage, and WDT. With excellent EMI immunity, it is well suited for IoT control, large and small smart home appliances, smart home systems, chargers, power supplies, drone/model aircraft, walkie-talkies, wireless communications, gaming consoles, and other industrial control and consumer applications.
