TM4C1294NCPDTT3R Description

The microcontroller TM4C1294NCPDT has a Direct Memory Access (DMA) controller known as micro-DMA (DMA). The DMA controller allows the CortexTM-M4F processor to offload data transfer duties, allowing for more efficient use of the processor and available bus bandwidth.

TM4C1294NCPDTT3R Features

• ARM? PrimeCell? 32-channel configurable μDMA controller

• Support for memory-to-memory, memory-to-peripheral, and peripheral-to-memory in multiple transfer modes

• Highly flexible and configurable channel operation

• Two levels of priority

• Design optimizations for improved bus access performance between the μDMA controller and the processor core

• Data sizes of 8, 16, and 32 bits

• Transfer size is programmable in binary steps from 1 to 1024

• Source and destination address increment size of byte, half-word, word, or no increment 678 June 18, 2014

• Texas Instruments-Production Data

• Micro Direct Memory Access (μDMA)

• Maskable peripheral requests

• Interrupt on transfer completion, with a separate interrupt per channel
