Complete a free, unlimited development toolchain with Cosmic's new C compiler, CXSTM8

ST expands the benefits of its popular STM8 microcontrollers to help make computing on smart devices more economical.

ST and Cosmic have collaborated to provide all software tools necessary for implementing, debugging, and fine-tuning STM8 applications for free. While free tools exist for other microcontrollers, they may be subject to limitations in functionality or code size. Cosmic’s free C-compiler (COS-C-COMPILER), announced for STM8, fully supports the entire STM8 family without restrictions, including the largest 128KB device.

Therefore, the cost to start prototyping based on this 8-bit microcontroller is only $8. This $8 is the price of the STM8S-DISCOVERY hardware kit, which allows you to run the main functions of the STM8S Access-Line microcontroller. This product family includes the STM8L ultra-low power line and the STM8AF and STM8AL automotive lines, offering over 120 products with various configurations of on-chip memory and package types, as well as peripherals such as communication interfaces, timers, and converters.

Michel Buffa, Group Vice President and Head of the Microcontroller Business Unit at ST, said, “The STM8 family has gained even more value in the 8-bit market, which accounts for about 40% of microcontroller sales,” adding, “We will do our best to ensure that STM8 is adopted in most of the tens of millions of applications based on the simplicity and cost-effectiveness of 8-bit microcontrollers.”

Luca Ubiali, Key Customer Manager at Cosmic, said, “Cosmic and ST have collaborated on multiple generations of STM8 microcontrollers and their C compilers, and the CXSTM8 is ideal for these architectures. We are pleased to offer the product’s superior performance and flexibility to all STM8 users for free. Furthermore, if you need to strengthen project safety requirements, you will be able to more easily achieve the field-proven stability of the CXSTM8 with Cosmic’s Unit Testing and RunTime Core Validation products.”
