Enhanced ARM® Cortex®-M Portfolio

Meet Your Unique Design Requirements with the Microchip SAM3 Family

The Microchip SAM3 family of ARM® Cortex™-M3 Flash-based microcontrollers (MCU) is expanding with 40 new devices in the mix that provide more memory options and more connectivity. With this high-performance, highly integrated and power-efficient portfolio, you’ll find just the right devices to meet your unique design requirements.

More Features

Get a broader scale of memory densities, greater cost-efficiency and more connectivity. You’ll have:

A full range of Flash memory options from 16 KB up to 1 MB
New peripheral sets for advanced connectivity, including Ethernet, dual CAN and high-speed USB MiniHost and device with on-chip physical layer (PHY)
And features including dual-bank Flash and dual-bank SRAM, as well as on-the-fly external memory scrambling

More Possibilities

With more memory densities in the portfolio, you’ll be able to meet the needs of your most cost-sensitive applications, as well as those requiring more memory for code and data storage or multi-tasking operations. Advanced connectivity capabilities are ideal for data concentrators, gateways and programmable logic controllers. You'll also experience safe in-system firmware upgrades and enhanced protection of external memories.

Look to the expanded SAM3 portfolio for devices with the right features and functions for designs in industrial automation, smart grids, medical equipment, building and home control, test and measurement systems, and computer and consumer peripherals. What’s more, SAM3 products provide an easy migration path from Microchip ARM7TDMI® SAM7S devices to Microchip ARM Cortex-M devices.

More Empowerment

The SAM3 portfolio natively supports the Microchip QTouch® Library, so you can add buttons, sliders and wheels functionality to your products. The device family also supports the Microchip 802.15.4-based wireless solution.

To accelerate your design process, you’ll have access to a full set of tools, from evaluation kits to debuggers and comprehensive software packages, including the Microchip Studio 6 integrated development environment (IDE). With the free Microchip Studio 6, which supports Cortex-M and Microchip AVR® MCU design, you’ll have access to nearly 1,000 example projects that will eliminate the need to write up to 50% of the low-level source code for your projects.

Enhancements to the SAM3 Family

New devices include:

SAM3N00 and SAM3N0 with 16 KB and 32 KB of Flash memory
SAM3S8 and SAM3SD8 with 512 KB of Flash memory and dual-bank Flash option
SAM3X featuring Ethernet, dual CAN interface and HS USB MiniHost and device with on-chip PHY. Memory options are 256 KB and 512 KB dual-bank Flash with up to 100 KB of dual-bank SRAM.
SAM3A featuring dual CAN interface and HS USB MiniHost and device with on-chip PHY. Memory options are 256 KB and 512 KB dual-bank with up to 100 KB of dual-bank SRAM.
SAM3U1 with 64 KB of Flash memory and HS USB with on-chip PHY
