Versatile, Small Footprint Direct Memory Access

The Arm CoreLink DMA-250 direct memory access (DMA) controller offloads memory movement tasks from the CPU to improve system performance and energy efficiency. It includes support for scatter-gather, memory-to-memory, memory-to-peripheral (and vice versa) transfers.

This DMA controller pairs well with the Arm Cortex-M52 and Arm Cortex-M33 processors or any AMBA High-Performance Bus (AHB) systems, where area and power constraints are key design considerations.

Features and Benefits

Light-Weight Data Transfer Control

Up to 32 virtual channels deliver versatile data transfers at the lowest area cost. Command chaining and trigger options bring low power to AHB data processing systems.

Built-In Security

Supports TrustZone for Armv8-M, enabling system-wide security to the smallest edge AI and embedded devices. DMA-250 embraces security by design, thereby helping systems achieve PSA Certified security certification more easily.

Highly Configurable Feature Set

Conceived to provide designers with the widest option of features and performance-to-area trade-offs. From command triggering options to the number of transfer channels, SoC designers can achieve fit-for-purpose design goals.
