• Memory Interfaces – External bus interface supporting 8-bank DDR2/LPDDR, LPDDR2, SDR/LPSDR and static memories; compatible with LPDDR, LPDDR2, DDR2, SDR and SRAM memory types.
• Storage and Flash – Integrated MLC/SLC NAND controller with programmable multibit ECC (PMECC) for robust NAND Flash support.
• Display and Touch – LCD controller and resistive touchscreen support for human‑machine interface applications.
• USB and High-speed I/O – USB Full Speed host and device capability (USB 2.0), plus multiple serial interfaces including UART, SPI, I2C and SDIO for diverse connectivity options.
• DMA and System Bus – Internal 133 MHz multi-layer bus architecture with a dual-port 8-channel DMA controller and eight DMA channels to sustain high peripheral throughput.
• Security and Cryptography – On-chip hardware accelerators supporting AES (up to 256-bit), FIPS-compliant SHA1/SHA256, a True Random Number Generator (TRNG), fuse bits for crypto key storage and a secure Boot ROM (specific to SAM9CN12).
• Power Management – Integrated power-on reset, reset and shutdown controllers, efficient clock gating, battery backup section, low-power oscillators and selectable PLLs for system and USB clocking.
• Package and Temperature – 217-LFBGA (15×15) surface-mount package with industrial operating temperature range of −40 °C to 85 °C; RoHS compliant.

Typical Applications

• Human-Machine Interfaces (HMI) – LCD controller and resistive touchscreen support enable responsive operator displays and control panels.
• Industrial Gateways and Controllers – High-performance core, multiple serial interfaces and DMA-capable bus architecture support data aggregation and protocol handling in industrial equipment.
• Embedded Storage and Media – NAND controller with PMECC and SDIO support provide robust on-board storage options for data logging and media applications.
• Secure Embedded Systems – Hardware AES/SHA accelerators, TRNG and secure Boot ROM (SAM9CN12) address secure boot and encrypted data requirements.

Unique Advantages

• Highly integrated peripheral set: On-chip LCD, touchscreen, USB host/device, NAND controller and multiple serial interfaces reduce BOM and simplify board design.
• Flexible memory support: Broad external memory compatibility (LPDDR/DDR2/SDR/SRAM) enables scalable memory configurations for performance or cost optimization.
• Security-ready architecture: Hardware crypto accelerators, TRNG and secure boot support enable deployment in applications requiring onboard security features.
• Industrial reliability: Industrial temperature rating (−40 °C to 85 °C) and surface-mount 217-LFBGA packaging support robust operation in demanding environments.
• Efficient data handling: Multi-layer 133 MHz bus and multi-channel DMA minimize CPU overhead for high-throughput peripherals and storage.
• Power-conscious design: Integrated clock gating, low-power oscillators and shutdown controller help reduce system power in active and standby modes.
