EFM32 Peripherals

High performance peripherals

Operating without CPU intervention

EFM32 is packed with peripherals built for low energy operation. Without sacrificing performance, the low power peripherals deliver high throughput and performance. This is possible with the use of innovative control techniques and peripheral reflex system (PRS). Peripherals can react and respond to input from external or internal triggers without any CPU intervention. In combination with the DMA controller the PRS enabled EFM32 systems benefit from an autonomous behavior resulting in reduced latency and energy consumption.
