SAM9N12/SAM9CN11/SAM9CN12

Description

The SAM9N and SAM9CN Arm926EJ-S™-based embedded MPUs offer the frequently-requested combination of user

interface functionality and high data rate connectivity, with LCD controller, resistive touchscreen, multiple UARTs, SPI,

I2C, full-speed USB Host and Device and SDIO.

These eMPUs support the latest generation of LPDDR/DDR2 and NAND Flash memory interfaces for program and data

storage. An internal 133 MHz multi-layer bus architecture associated with eight DMA channels and distributed mem-

ory—including a 32-Kbyte SRAM—sustains the high bandwidth required by the processor and the high-speed periph-

erals.

The SAM9CN devices offer on-chip hardware accelerators with DMA support that enable high-speed data encryption

and authentication of transferred data or applications. Supported standards are up to 256-bit AES, and FIPS Publication

180-2 compliant SHA1 and SHA256. A True Random Number Generator is embedded for key generation and exchange

protocols. The devices also feature fuse bits for crypto key (SAM9CN12), user configuration (SAM9N12 and

SAM9CN11) and device configuration (all). The SAM9CN12 includes a secure Boot ROM; the SAM9N12 and

SAM9CN11 include a standard Boot ROM.

The I/Os support 1.8V or 3.3V operation and are independently configurable for the memory interface and peripheral I/

Os. This feature eliminates the need for any external level shifters, while 0.8mm ball pitch packages lower PCB cost

and complexity.

The SAM9N and SAM9CN power management controllers feature efficient clock gating and a battery backup section

that minimizes power consumption in active and standby modes. The following table presents the embedded features

of each device.
