The AT91SAM9XE256 is a monolithic ARM9-based Flash microcontrollers that combines a 200-MIPS ARM926EJ-S processor core with up to 256K bytes of high-performance on-chip Flash. It offers an unrivalled combination of performance and functionality on a single chip, making these Flash microcontrollers ideal for space-constrained applications where high performance is required.
The SAM9XE256 is designed to reuse the maximum of the peripherals and technology developed for Atmel’s ARM7-based SAM7 family. In addition, the same support infrastructure is used for both the SAM7 and the SAM9XE series, making the migration between both microcontroller families smooth and easy.
The SAM9XE256 provides multiple networking/connectivity options with on-chip USB 2.0 Full Speed Host and Device Ports, an Ethernet 10/100 Base-T MAC as well as a two-slot Multimedia Card Interface (SDCard/SDIO and MultiMediaCard Compliant), a Synchronous Serial Controller (SSC), four USARTs, two master/slave Serial Peripheral Interfaces (SPI), a debug UART and two Two Wire Interfaces (TWI).
The six-layer system bus matrix is linked to the Memory Management Unit of the processor core, as well as to distributed DMA channels on the USB Host, Ethernet and Image Sensor Interface to ensure uninterrupted internal data flows with minimum processor overhead. This concept is extended to peripherals via the Peripheral DMA Controller (PDC) that communicates with DMA interfaces on the USB Device and all other serial I/Os. This industry-leading distributed DMA architecture ensures that internal data transfers occur at maximum possible bandwidth with minimal processor intervention. It enables the SAM9XE256 to perform complex data processing at the same time as high-speed data transfers.
