Overview of AT91SAM9CN11-CUR – IC MPU SAM9CN 400MHZ 217LFBGA
The AT91SAM9CN11-CUR is a single-core, 32‑bit microprocessor based on the ARM926EJ‑S core, running at up to 400 MHz. It combines a high-performance embedded MPU core with extensive memory and peripheral interfaces aimed at industrial embedded designs that require user interfaces, storage, and high data‑rate connectivity.
Designed for integration and system-level functionality, this device provides multi-bank external memory support, display and touchscreen controllers, dual full-speed USB ports, hardware cryptography and a compact 217‑LFBGA (15×15) surface‑mount package for industrial temperature operation.
Key Features
- Core & Performance ARM926EJ‑S 32‑bit core up to 400 MHz with 16 KB instruction and 16 KB data caches and an MMU; internal 133 MHz multi‑layer bus and DMA support sustain high peripheral throughput.
- Memory & Storage On‑chip memory includes a 128‑KB internal ROM (standard boot) and 32‑KB internal SRAM, plus a 32‑bit External Bus Interface supporting LPDDR, LPDDR2, DDR2, SDR and SRAM. Integrated MLC/SLC NAND controller with programmable multibit ECC (PMECC) is provided for robust flash storage.
- Display & User Interface LCD controller and resistive touchscreen controller support development of graphical human‑machine interfaces and embedded display applications.
- Connectivity & Peripherals Dual USB 2.0 full‑speed ports (Host and Device), multiple UARTs, SPI, I2C and SDIO interfaces offer a broad set of I/O for connectivity and peripheral expansion.
- Security & Crypto On‑chip hardware accelerators support AES (up to 256‑bit) and FIPS‑180‑2 compliant SHA1/SHA256, complemented by a True Random Number Generator for key generation and secure protocols.
- System & Power Management Integrated power management with clock gating, shutdown controller, watchdog timer, RTC and low‑power oscillators to optimize active and standby power consumption.
- Package & Environmental 217‑LFBGA (15×15) surface‑mount package, industrial grade operation from ‑40°C to +85°C, and RoHS compliance for regulated environments.
- Additional Interfaces External Bus Interface (EBI/EMI) support for flexible system integration.
- Graphics Acceleration No dedicated graphics acceleration; display handling is via the integrated LCD and touchscreen controllers.
Typical Applications
- Industrial HMI and Control Panels Integrated LCD and touchscreen controllers plus industrial temperature range make it suitable for human‑machine interfaces and operator panels.
- Embedded Storage and Data Loggers NAND controller with PMECC and wide external memory support enable reliable local storage for logging and archival applications.
- Connectivity Gateways and USB Devices Dual full‑speed USB ports, SDIO and multiple serial interfaces support peripheral connectivity and data transfer in instrumentation and gateway systems.
- Secure Embedded Systems On‑chip AES/SHA accelerators and TRNG provide cryptographic building blocks for secure boot, authentication and encrypted communications.
Unique Advantages
- Highly integrated MPU with rich peripherals: Reduces external components by combining core, memory interfaces, display controllers and multiple serial buses in one device.
- Broad external memory support: Native support for LPDDR/DDR2/SDR and SRAM enables flexible memory architectures for performance or cost optimization.
- Built‑in security engines: Hardware AES and SHA accelerators plus TRNG simplify implementation of encryption and secure key management.
- Industrial readiness: 217‑LFBGA package and ‑40°C to +85°C operating range target robust deployments in industrial environments.
- System throughput and DMA: Multi‑layer bus with DMA channels and on‑chip SRAM supports high data rates between core and peripherals.
- Compact SMT package: 0.8 mm ball pitch LFBGA reduces PCB area while supporting surface‑mount assembly.
