  • CMS32L051

    64KB Flash,64MHz,single-cycle multiplier. has rich peripheral resources such as high-speed communication interface, RTC, etc. which are widely used in consumer electronics, medical health, household appliances, measurement and industrial control. 

    Datasheet >

    The CMS32L051 is a mainstreaming MCU series that we designed based on ARM-Cortex M0+ which has a operating frequency being as 64MHz, operating voltage being ranged within 1.8V~5.5V, 64KB Flash and 1.5KB Data Flash, 8KB SRAM, 45 GPIO, integrated ADC, general timer, RTC, SPI, I2C DMA and different kinds of peripheral facilities. This series is mainly utilized in consumer electronics, medical healthcare facilities, household appliances, surveying instruments, industrial controls and etc.


    Most of the digital functions support a free IO mapping.The chip is packaged in the forms of QFN20、TSSOP20、QFN24、SSOP24、LQFP32、QFN32、QFN40、LQFP48.
