AT91SAM 32-bit ARM-based Microcontrollers

Atmel's AT91SAM7S, AT91SAM7SE, AT91SAM7L, AT91SAM7X and AT91SAM9, AT91SAM9XE Smart ARM®-based microcontrollers offer:

• Proven architecture based on ten years' experience in ARM-based standard products
• Deterministic behavior:
  • Predictable response to a real-time event within a specified number of clock cycles
• Significant enhancements to the basic ARM processor:
  • Peripheral DMA eliminates bottlenecks in memory-to-peripheral transfers
  • Advanced interrupt control enhances real-time performance
  • Single-instruction bit set/reset simplifies application code
• Embedded Flash memory for flexible code and reference data storage
• Connectivity: USB, Ethernet, SPI, USART, etc.
• Security: AES/TDES accelerators, memory lock bits, etc.
• Code compatibility across all products
• Low-cost development tools
• Software device drivers and an extensive code library to facilitate application development
• Extensive compiler, operating system, compiler and application support from industry-leading third parties

… all based on the industry-standard ARM 32-bit RISC processor architecture.
