STM8 8-bit microcontrollers

STMicroelectronics' new 8-bit microcontroller platform is designed to offer outstanding levels of performance and cost-effectiveness in a wide range of applications.

Implemented around a high-performance 8-bit core and a state-of-the-art set of peripherals, the STM8 platform uses an ST-proprietary 130nm embedded non-volatile memory technology.

ST has introduced the first STM8 family, and is going to periodically announce dedicated families or variants along the year of 2008 and 2009.

New core architecture boosts performance

Key features	Benefits
32-bit memory interface and 3- stage pipeline	Key for the performance improvement leads to an average of 1.6 CPI with 20MIPS peak performance
16-bit index register and stack pointer	Better code density and speed when managing tables
16-MBytes linear address space	No overhead for paging operations above 64-Kbytes of memory
Enhanced stack pointer operations	To better support C-programming and real-time operating systems
Advanced addressing modes	Big improvement for supporting C-programming, leading to better code density and efficiency
New instructions	Increased speed of arithmetic operations

Technology platform

Key features		Benefits
