CA51F1 series chips are 8-bit microcontrollers based on 1T 8051 core. Usually, the running speed is 10 times faster than the traditional 8051 chips, and the performance is superior. Built-in 16K Flash program memory can be repeatedly programmed, which brings great convenience to users. It not only retains the basic characteristics of the traditional 8051 chip, but also integrates functional modules such as 12-bit ADC, Touch Key, 16-bit PWM, UART, IC and low voltage detection (LVD). Support three power saving modes: IDLE, STOP and low-speed operation to adapt to applications with different power consumption requirements. Mainly used in: smart desk lamps, smart light strips, toys and consumer electronic products.
