About UsNew STM32C0 Microcontroller Series Offers Cost Affordability
STMicroelectronics STM32C0 series is ideal for low-cost equipment like smoke detectors and industrial sensors
STMicroelectronics STM32C0 Series is now in high volume production and is also covered by ST's 10-year longevity program. The STM32C0 is the most affordable 32-bit microcontroller in the STM32 Range.
In assuring availability, the new STM32C0 series is ideal for equipment like home appliances, industrial pumps, fans, smoke detectors, typically served by simpler 8-bit and 16-bit MCUs. The modern, 32-bit design of the STM32C0 permits improvements such as faster response, extra functions, and network connection at similar overall cost and power consumption.
“The next generations of smart appliances and industrial controllers must be easy to use, ultra-competitively priced, and with assured supply,” said Daniel Colonna, STM32 Marketing Director at STMicroelectronics. “By delivering on these requirements, our new STM32C0 general-purpose entry-level MCUs introduce exciting options to the 8-/16-bit applications space, with the added benefits that come with the broad and powerful STM32 ecosystem.”
