AT91SAM9M10C-CU

The AT91SAM9M10C-CU is a multimedia-enabled embedded microprocessor based on a single ARM926EJ-S core running at 400 MHz. It integrates video decode, display and touchscreen controllers, audio and camera interfaces, Ethernet 10/100, and multiple high-speed I/O options to address connected human-machine interface and media applications.

With support for DDR2/LPDDR and NAND Flash memory interfaces, a 64 Kbyte internal SRAM configurable as tightly coupled memory (TCM), and a 133 MHz multi-layer bus with 37 DMA channels, the device is optimized for sustained data bandwidth in industrial-grade systems.

Key Features

• Core  ARM926EJ-S single core at 400 MHz with separate instruction and data caches and MMU for embedded application control and operating system support.
• Memory and Storage  Support for DDR2, LPDDR, SDR/LPSDR, SRAM and SLC NAND Flash interfaces; includes 64 Kbyte internal SRAM and 64 Kbyte internal ROM with bootstrap routine.
• Multimedia and Display  Integrated universal video decoder supporting H.264, MPEG‑4, MPEG‑2, VC‑1 and H.263, plus LCD controller, resistive touchscreen controller and image post-processing (scaling, color conversion, rotation).
• Connectivity  10/100 Mbps Ethernet and three USB 2.0 interfaces for networked and peripheral connectivity.
• Audio and Peripherals  Audio interfaces including AC97 and camera interface for multimedia input/output.
• System and Performance  133 MHz multi-layer AHB bus matrix, 37 DMA channels and dual PLLs (one optimized for USB high speed) for high throughput and peripheral coordination.
• Security and Utilities  Embedded True Random Number Generator and a range of timers and controllers including RTC, PIT and watchdog.
• Power and Low‑Power Modes  Three software-selectable low-power modes—Idle, Ultra Low-power and Backup—plus efficient clock gating and battery backup features to reduce power in active and standby states.
• Package and Temperature  324-TFBGA (15 × 15 mm) surface-mount package with industrial operating range of −40 °C to 85 °C; package designed for 0.8 mm ball pitch PCB manufacturing.

Typical Applications

• Media-rich Displays and Control Panels  Drives graphical user interfaces and video playback for building automation, HMI units and commercial touch panels using integrated LCD and touchscreen controllers.
• Point-of-Sale Terminals  Supports transaction displays, peripheral connectivity and network interfaces for POS systems requiring multimedia and Ethernet connectivity.
• Entertainment and Internet Appliances  Enables video decoding, audio interfaces and USB connectivity for set-top boxes, streaming appliances and consumer devices.
• Industrial and Medical Devices  Industrial temperature rating, robust memory interface options and low-power modes suit embedded control and monitoring equipment in commercial and medical contexts.

Unique Advantages

• Multimedia Integration: Hardware video decoder, LCD controller, touchscreen and camera interfaces reduce external device count and simplify board design for display-centric products.
• High-Bandwidth System Architecture: 133 MHz multi-layer AHB bus and 37 DMA channels deliver sustained data throughput for video, memory and peripheral transfers.
• Flexible Memory Support: Native support for DDR2, LPDDR, SDR/LPSDR, SRAM and NAND Flash provides design flexibility for cost and performance trade-offs.
• Industrial Temperature Range: Rated for −40 °C to 85 °C to meet the environmental demands of industrial and commercial embedded applications.
• Low-Power Operation: Multiple software-selectable low-power modes and efficient clock gating reduce power consumption in active and standby states.
• Compact Surface-Mount Package: 324-TFBGA (15 × 15 mm) with 0.8 mm ball pitch supports low-cost PCB manufacturing and compact system designs.
