James Wiart, director of marketing and applications for microcontrollers in Greater China and South Asia, said that according to a market research report released by IHS iSuppli in March, STMicroelectronics' total camp of global general-purpose microcontrollers and safety microcontrollers in 2013 The ranking is second only to Renesas Electronics.
Wiart further pointed out that in fact, STMicroelectronics was still only in the eleventh in 2007, but after releasing the first 32-bit microcontroller and strengthening the security component lineup, the company has quickly climbed to the top of the list, and the future will At the same time, with high-performance and low-power 32-bit microcontrollers to develop revenue sources, the first place in the next few years.
James Wiart, director of marketing and applications for microcontrollers at ST Greater China and South Asia, noted that the Cortex-M0+ core microcontroller is suitable for the industrial sensor market where power consumption is critical.
It is understood that for different application markets, STMicroelectronics has separately released a series of 32-bit microcontroller products with low-power to high-performance specifications, including STM32F3 with Cortex-M4 core and integrated floating-point unit (FPU). And STM32F1 and STM32F0 with Cortex-M3 and M0 processor cores respectively. Today, the company officially adds a new member of the Cortex M0+, the STM32L0, to the 32-bit microcontroller lineup. Compatible with the full range of pinouts, it offers customers new component options with ultra-low power design requirements.
Wiart emphasizes that the power consumption requirements of industrial applications, wearable devices or RF communication systems are becoming more stringent, so the STM32L0 operates at a mode power consumption of only 87 microamps (μA)/MHz when random access memory When the body (RAM) data is fully retained, the power consumption mode of the power-off mode is 440 nanoamperes (nA), and the wake-up time from the shutdown mode to the working mode is only 3.5 microseconds (μs). This energy-saving mode is suitable for always turning on. Medical monitors/trackers, industrial sensors and smart home products.
In particular, STMicroelectronics has increased the operating temperature range of the STM32L0 from -40 to 100 °C from the previous generation of microcontrollers to -40 to 125 ° C, and still maintains stable low power performance at high temperatures, so For industrial sensors that rely on batteries, the STM32L0 is ideal for extending battery life.
