Microcontrollers
STM8
The STM8 is a platform of technologies, IPs and tools which forms the basis of STMicroelectronics’ comprehensive family of
8-bit microcontrollers. These cover a wide range of applications from low-power and consumer electronics, through home
appliances and factory automation to automotive segments.
The platform provides outstanding levels of digital and analog performance combined with a high level of cost effectiveness.
Implemented around a high-performance 8-bit core and a state-of-the-art set of peripherals, the microcontrollers in the STM8
family are manufactured using an ST-proprietary 130 nm embedded non-volatile memory technology.
STM8 core
The STM8 core is an evolution of the
industry-standard ST7 core. It has
been significantly improved to reach
1.6 cycles per instruction and up to
24 MHz clock frequency.

STM8S MCU family for industrial applications
STMicroelectronics’ STM8S family of general-purpose 8-bit Flash microcontrollers
offers ideal solutions for industrial and appliance market requirements. An
advanced core version combined with a 3-stage pipeline ranks the STM8S
microcontroller in the top position for performance. The true embedded EEPROM
and the calibrated RC oscillator bring a significant cost effectiveness to the majority
of applications. An easy-to-use and intuitive development environment contributes
to improving time to market.
STM8L ultra-low-power MCU family
STMicroelectronics proposes an ultra-low-power family of MCUs based on the
8-bit and 32-bit cores. The STM8L MCU family, based on the STM8 proprietary
core, is the entry point of the platform.
The STM8L family combines high performance and ultra-low power consumption
using a new proprietary ultra-low leakage process and optimized architecture. This
family is declined in three different lines, making the STM8L an optimal family to
support many applications with special care on power savings.
The STM8L101 is the entry point for the ultra-low-power 8-bit portfolio. It is cost
optimized and offers a high level of integration in an ultra-small footprint. The
STM8L151 is the feature-rich 8-bit solution. The STM8L152 has an additional
segment LCD driver compared to the STM8L151.
STM8A automotive MCU family
This product line of 8-bit Flash microcontrollers responds to the specific needs
of automotive applications. From product specifications, on through design and
manufacturing, the focus is on reliability, application robustness and low system
cost. The integrated true data EEPROM features top notch endurance and data
retention throughout the full temperature range. With its extended temperature
range up to 150 °C ambient temperature, the STM8A is the ideal and economic
solution for the growing market of automotive 8-bit applications.
Tools for everyone
The ecosystem of advanced STM8
tools is a scalable offer to satisfy all
needs. From free-of-charge software
tools, including free compiler licenses,
to low-cost starter kits and affordable
evaluation boards for multiple
applications, ST tools and support
open the door to the ST microcontroller
universe.
ST’s fully tested, optimized and
validated downloadable source-code
libraries are immediately available for
new application development.
