  • CMS8S5880

    Enhanced 1T 8051, 16KB Flash, 24MHz main frequency. The CMS8S5880 series of MCUs have low power consumption and convenient development. They are widely used in battery-powered consumer products, such as beauty instruments, 2.4G light controls, game controllers, pan-tilts, etc.


    CMS8S5880 is an enhanced Flash MCU with 1T 8051 core, working voltage 2.1V-4.5V, main frequency up to 24MHz, I/O up to 18, ADC, PWM, 2 UART, 1 SPI, 1 I2C, sleep state The lower quiescent current is less than 6uA, and it can work from -40°C to 105°C. Packages such as TSSOP20/QFN20 are available.
