EFM8™ 8-bit microcontrollers without compromise

2021-10-30

EFM8 microcontrollers are based on the popular 8051 core. The 8051 architecture ecosystem represents nearly 25% of the existing MCU market.
●Select a secure architecture
■The EFM8 is based on a Harvard architecture, allowing it to only execute code fetched from program memory and allows locking of program memory to prevent unauthorized examination. These are two advantages in the EFM8 hardware that protect a product from security attacks.
●Select a low latency system
■Variations in interrupt response time can cause adverse effects in some applications, causing, for example, audio distortion or motor noise and vibration. With the EFM8 it's easy to work “close to the metal” and have full control over the entire system.
●Select a simple solution
■The EFM8 microcontroller is ideal for processing 8-bit data that comes from port I/O or sensor inputs. A great many applications don’t require complex mathematics processing and benefit significantly from the code density advantages of an 8-bit processor when not tasked with 16-bit or 32-bit mathematics. Human interface functions, sensor interfaces, and distributed processing functions are examples that easily benefit from the simplicity of the EFM8 solutions.
