About the STM32L0 Cortex-M0+ processor and core

peripherals

The STM32L0 Cortex-M0+ processor is an entry-level 32-bit ARM Cortex processor

designed for a broad range of embedded applications. It offers significant benefits to

developers, including:

•

A simple architecture that is easy to learn and program.

•

Ultra-low power, energy-efficient operation.

•

Excellent code density.

•

Deterministic, high-performance interrupt handling.

•

Upward compatibility with Cortex-M processor family.

•

Platform security robustness, with optional integrated Memory Protection Unit (MPU).

Figure 1. STM32L0 Cortex-M0+ implementation

The STM32L0 Cortex-M0+ processor is built on a highly area and power optimized 32-bit

processor core, with a 2-stage pipeline Von Neumann architecture. The processor delivers

exceptional energy efficiency through a small but powerful instruction set and extensively

optimized design, providing high-end processing hardware including a single-cycle multiplier.

The STM32L0 Cortex-M0+ processor implements the ARMv6-M architecture, which is based

on the 16-bit Thumb

instruction set and includes Thumb-2 technology. This provides the

exceptional performance expected of a modern 32-bit architecture, with a higher code

density than other 8-bit and 16-bit microcontrollers.
