AT91SAM9XE512 概述

The AT91SAM9XE512 is a monolithic ARM9-based Flash microcontrollers that combines a 200-MIPS ARM926EJ-S processor core with up to 512K bytes of high-performance on-chip Flash. The AT91SAM9XE512 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 AT91SAM9XE512 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 AT91SAM9XE512 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).
