  • CMS8H5109

    A CMS8H5109 is an 8-bit SOC chip with 8051 CPU core, instruction set being compatible with MSC-51, general IO. Built-in a 24-bit Σ-ΔADC with the maximum operating frequency of 48MHz. The chip’s operating voltage is ranged within 2.6V-4.4V. The chip also support the internal clock and together with a digital mapping to an arbitrary GPIO.


    Datasheet >

    The CMS8H5109 series MCUs are 8-bit SOC designed based on 8051 core.

    The chip possesses a operating frequency being as 48MHz, operating voltage being within 2.6V~4.4V, with 64KB Flash Memory, 4.25KB SRAM, 4KB Data Flash, 16KB Boot Flash, 12 GPIOs, built-in high-precision 12-bit ADC, built-in 24-bit Σ-ΔADC, internl gaining being as(1/2/4/8/16/32/64/128/256), effective resolution of 20.6 bits(PGA=128、ODR=10Hz), internal buzzer driver, 5 16-bit general timer.

    For the chip’s communication module, 2 UART & one I2C are supported.

    The chip operate in a temperature range between -40 ℃ and 85℃ and come in a SOP20 package.
