AT91SAM9CN12-CFUR

The AT91SAM9CN12-CFUR is a single-core 32-bit microprocessor based on the ARM926EJ-S core, running at up to 400 MHz. Designed for embedded systems, it combines a high-performance processor core with integrated peripherals and memory interfaces to support user interfaces and high-data-rate connectivity in industrial applications.

With on-chip security features, a flexible memory subsystem and a compact 247-ball LFBGA package (10×10, surface mount), this MPU targets designs that require processing headroom, robust connectivity and extended temperature operation from −40 °C to 85 °C.

Key Features

• Core & Performance  ARM926EJ-S 32-bit processor core running up to 400 MHz, with instruction and data caches and an MMU to support complex embedded operating environments.
• Memory & DMA  Internal memory includes a 128-Kbyte ROM and 32-Kbyte SRAM, plus a 133 MHz multi-layer bus architecture and an 8-channel DMA controller to sustain high peripheral and memory bandwidth.
• Memory Controllers  Dedicated controllers for LPDDR, LPDDR2, DDR2, SDR and SRAM allow direct connection to a broad range of external memory types for program and data storage.
• Storage & NAND Support  Integrated MLC/SLC NAND controller with programmable multibit ECC (up to 24-bit PMECC) for reliable flash storage management.
• Display & Touch  On-chip LCD controller and resistive touchscreen support enable integrated human‑machine interface designs.
• Connectivity & Peripherals  Multiple UARTs, SPI, I2C, SDIO and two USB 2.0 full-speed interfaces (Host and Device) provide extensive I/O and connectivity options for peripherals and external systems.
• Security & Crypto  On‑chip hardware accelerators with DMA support implement AES (up to 256-bit) and FIPS 180-2 compliant SHA1/SHA256, along with a True Random Number Generator (TRNG) and fuse bits for crypto and device configuration. The SAM9CN12 includes a secure Boot ROM.
• System & Power Management  Integrated clock generator, power management controller, watchdog, real-time clock and selectable low-power oscillators enable power-optimized system designs and battery backup support.
• External Bus & I/O Voltage Flexibility  32-bit External Bus Interface (EBI) supporting 8-bank DDR2/LPDDR and static memories; I/Os support 1.8 V or 3.3 V operation selectable per interface to simplify mixed-voltage designs.
• Package & Industrial Grade  247-ball LFBGA (247-BGA, 10×10) surface-mount package with 0.8 mm ball pitch and industrial temperature range (−40 °C to 85 °C) for space-efficient, rugged board designs.
• Standards & Compliance  RoHS compliant manufacturing and package choices suitable for industrial applications.

Typical Applications

• Human‑Machine Interfaces (HMI)  Drive LCD panels and resistive touchscreens while handling application logic and graphics via the ARM926EJ-S core and integrated display controller.
• Industrial Control & Automation  Control systems and gateway devices benefit from the industrial temperature rating, extensive peripheral set and robust memory interfaces.
• Secure Connectivity Appliances  Use on‑chip AES/SHA accelerators, TRNG and secure Boot ROM to implement encrypted communications and secure boot in networked equipment.
• Embedded Storage & Media Controllers  NAND controller with PMECC and SDIO support enables reliable flash-based storage and removable media applications.

Unique Advantages

• Integrated security accelerators: Hardware AES and SHA engines plus a TRNG and secure Boot ROM simplify design of secure systems without external crypto peripherals.
• Flexible memory subsystem: Support for LPDDR/DDR2/SDR and SRAM via a 32-bit EBI lets designers choose memory types to match performance, cost and power targets.
• Rich on‑chip connectivity: Multiple serial interfaces, dual USB 2.0 full‑speed ports and SDIO reduce external component count and speed time-to-market.
• Industrial temperature and package density: 247-BGA 10×10 package with −40 °C to 85 °C rating enables compact, rugged designs for industrial deployments.
• High-bandwidth system architecture: 133 MHz multi-layer bus and DMA channels sustain data movement between memory and peripherals for demanding embedded workloads.
