AT91SAM9XE256

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.

AT91SAM7L64

The AT91SAM7L64 is a member of a series of high-performance, ultra-low power ARM7TDMI®-based microcontrollers, embedding power switches controlling multiple power islands and programmable voltage regulators to reduce power consumption in active and standby modes. In active mode, the power consumption is optimized via a programmable operating voltage, operating frequency, and peripheral clock activity, and the use of DMA instead of the CPU for data transfers. The SAM7L64 operates in single supply mode down to 1.8V and consumes 0.5mA/MHz typical in active mode when executing code out of its Flash memory.

 

The power consumption in the different standby modes is controlled via power switches, scalable voltage regulators, and the use of sampling techniques on Voltage Monitors, Power On Reset and Brown Out Detector instead of continuous measurement. This provides a higher level of granularity than is available in competing products, while achieving at least the same levels of power saving. In power down mode, the AT91SAM7L consumes only a typical 100nA, which is believed to be a unique feature for 32-bit MCUs.  Datasheet and application document
