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
True Data EEPROM with read while write No compromise with emulated E²data. The risk of data corruption is eliminated. Moreover, the read while write configuration allows accurate software management
Up to 256 Kbytes of program memory, up to 128 pin packages, 145 °C  temperature range STM8 is a perfect fit for strategic platform choices and facilitates  re-use of design concepts
Large voltage range from 1.65 to 5.5V Device families can cover a wide scope of  application segments including automotive, industrial, consumer and battery operated devices
Ultra-low-power design (clock gating, low-power Flash with power-off capability) Reduced overall run and wait mode current consumption by turning off clocks of unused peripherals or Flash
Multiple modular technology options Allows to implement solutions for high speed, ultra low power, high integration level, analog performance
Robust and proven technology The products are designed to withstand a high level of external disturbances, leading to robust applications without the expense of external protection elements
Multiple internal clock sources. Smart clock and peripherals management Allows to drastically reduce power consumption and noise emission
Compatibility across the families through modular peripheral set Simplifies design reuse improving time to marked
