|STMicroelectronics introduces a new 8-bit microcontroller platform 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 is manufactured using an ST-proprietary 130nm embedded non-volatile memory technology.
In performance, the STM8 leverages a Harvard architecture with 16-bit index registers and stack pointer, a 16Mbyte linear address space, advanced addressing modes and other features designed to optimally support C-programming to deliver leading-edge CPU performance in both speed and code density. The core reaches an average of 1.6 cycles per instruction with 20 MIPS of peak performance at 24MHz using a 3-stage pipeline.
The technology has been chosen with the aim of reducing system costs through a high integration level, the ability to embed non-volatile data memory and to provide excellent analog performance in a wide voltage range from 1.65V to 5.5V. For example, the I/O pads have been designed to withstand a high level of external disturbances, leading to robust applications without the expense of external protection elements. The STM8 platform offers real embedded EEPROM with a performance in endurance and retention comparable to those of external components, making complex Flash-based emulation strategies obsolete. The available on-chip Flash program memory sizes will range up to 256K. The technology options allow high-speed operation as well as drastically reduced power consumption. All these technological advantages will be available in automotive grade products that operate at temperatures of up to 145°C.
The STM8 peripherals are homogeneous across ST’s new 32-bit µC families such as the STM32 range, making the STM8 a perfect complement to ST’s 32-bit MCU portfolio.
