SOC(Shenzhen SinOne Microelectronics) SC92F7350M08U

The SC92F735X series is an enhanced 1T 8051-core industrial-grade Flash microcontroller, with an instruction set fully compatible with the traditional 8051 product family. The SC92F735X integrates 8 Kbytes Flash ROM, 256 bytes SRAM, 128 bytes EEPROM, up to 18 GP I/Os, 6 external interrupt-capable I/Os, three 16-bit timers, nine 12-bit high-precision ADC channels, six independent 8-bit PWM channels, tiered I/O drive control (P0 and P2 ports), an internal 1% high-precision high-frequency 24/12/6/2 MHz oscillator, a ±4% accuracy low-frequency 128 kHz oscillator, UART and other communication interfaces. To enhance reliability and simplify customer circuitry, the SC92F735X also integrates high-reliability circuits including a 4-level selectable voltage LVR, 2.4V reference ADC voltage, and WDT. The SC92F735X offers outstanding EMI immunity, making it well suited for IoT control, large and small smart appliances, smart home systems, chargers, power supplies, drone/model aircraft, walkie-talkies, wireless communications, gaming consoles, and other industrial control and consumer applications.
