test

Enhanced 8051 micro-controller, ROM 4K bytes, RAM 256 bytes

12-bit SAR ADC

• 10 external channels
• Monitors the NTC circuit, open-circuit, and short-circuit for safety

16-bit PWM

• Controls buzzer output

Supports SPI, UART, and I2C interface

High noise and electrostatic discharge (ESD) immunity

• Enables stable operation despite high-noise loads, including solenoid valve and water pumps, controlling water flow and pressure, and heating wires, controlled by silicon controlled rectifiers (SCRs)
