This series is an industry-grade Flash microcontroller with enhanced high-speed 1T 8051 core integrated with water level detection function, and its instruction sets are fully compatible with traditional 8051 series.

This series integrates with 4 water levels detection modules, 16 Kbytes Flash ROM, 1 Kbytes SRAM, 128 bytes EEPROM, up to 26 GP I/Os, 13 externally interruptible IOs, 3 16-bit timers, 11-channel 12-bit high-precision ADC, 6-channel independent 10-bit PWM, internal 1% high-precision high-frequency 12/6/2MHz oscillator and 4% precision low-frequency 128K oscillator, externally-connected crystal oscillator, one UART, one UART/SPI/IIC communication port SSI.

To improve the reliability and simplify the customer-specific circuits, this series has internally integrated with 4 levels of optional low voltage reset (LVR), 2.4V ADC reference voltage, low-power consumption (WDT) and other highly reliable circuits. It is characterized with excellent anti-interference performance and water level detection function, which is suitable for water level detection and master control in various use scenarios, such as intelligent household appliances and smart home, IoT, wireless communications, game machines, and other industry control and consumer applications.
