  • CMS80F262x

    This series of chips is cored with enhanced 1T 8051 with max clock frequency of 48MHz. Both LCD driving and LED driving are supported which makes the chip widely implemented in smart homes, new energy management, medical electronics healthcare, Small home appliances, motor controls, commerical & industrial management and etc.

    Datasheet >

    The CMS80F262x series are chips designed by us with enhanced 1T flash MCU. the max clock frequency of this chip is 48MHz, together with the operating voltage being ranged within 2.1V~5.5V, the Flash memory being as 64KB, the XRAM being as 4KB, general RAM being as 256B, the Data Flash being as 1KB.

    There are 46 GPIOs, 6-channel enhanced PWM, LCD & LED display ports, build-in 12-bit ADC, 2-channel analogue comparator, 5 16-bit general timer, 4-channel UART, 1-channel SPI in the chip.

    This series of chip we design fulfils all industrial grade requirements with operating temperature ranged within -40~-105 ℃ and are available in SOP28,LQFP32, LQFP44 & LQFP48 packages.
