Improved Deterministic Performance for Real-time Applications
The Atmel® SAM7S/SE ARM7TDMI® Flash MCU provides a strong migration path for 8/16-bit microcontroller users seeking additional performance, extended memory, and optimized system integration. The products feature high-speed Flash, SRAM, and extensive peripherals, as well as a complete set of system functions to minimize the number of external components. Peripheral DMA Controller channels eliminate processor bottlenecks during peripheral-to-memory transfers to maximize performance. Selected devices feature an External Bus Interface that provides access to external NAND Flash, SDRAM, CompactFlash, SRAM and ROM storage.
Extensive peripherals, uncompromised performance — Featuring an extensive peripheral set that includes USB 2.0 Device, USART, SPI, SSC, TWI, and an 8-channel 10-bit ADC. Architectured to maximize processor performance and efficiency.
Highly integrated design reduces costs and BOM — Combining the ARM7TDMI processor with on-chip Flash and SRAM, a wide range of peripheral functions and power and reset management on a single, integrated chip provides maximum flexibility, while minimizing the need for expensive additional components. The result is a streamlined bill of materials (BOM), faster development, and reduced cost.
Supports true in-application programming with dual-bank Flash — Flash memory on select models is arranged in two separate banks that allow the device to be programmed simultaneously with application execution. A dual-bank implementation protects the application against potentially catastrophic failure from unexpected power outages during firmware updates.
Comprehensive ecosystem and tools — To help speed development, SAM7S/SE microcontrollers are fully supported by a worldwide ecosystem of industry-leading suppliers of development tools, operating systems and protocol stacks.
