CA51M020T3
The CA51M020T3 chip is an 8-bit microcontroller based on the 1T 8051 core, which not only retains the basic characteristics of traditional 8051 chips, but also runs 10 times faster than traditional 8051 chips in general, with superior performance. The chip is equipped with 4KB MTP program memory, 256Byte internal RAM, 256Byte external RAM, and 512Byte EEPROM. It also integrates functional modules such as 18 channels of 12 Bit ADC, 3 channels of 16 Bit PWM, 1 channel of hardware LED0RGB cascade control, 1 channel of I2C, 1 channel of UART, and low voltage detection (LVD). Supports three power-saving modes: IDLE, STOP, and low-speed operation to adapt to applications with different power consumption requirements. Its powerful functions and superior anti-interference performance make it widely applicable to various household appliances and consumer products.
