AT91SAM9263B-CU-999

The AT91SAM9263B-CU-999 is a 32-bit microcontroller based on the ARM926EJ-S core running at 200 MHz. It integrates a high-bandwidth on-chip bus matrix, dual external memory buses, display and imaging controllers, and a broad set of peripheral interfaces tailored for embedded systems.

Designed for embedded and industrial applications, the device targets systems that require integrated display, multimedia and connectivity features — for example, navigation and industrial HMI applications — delivering performance and system-level integration in a 324‑TFBGA (15×15) surface-mount package with industrial temperature range.

Key Features

• Core ARM926EJ-S single 32-bit core at 200 MHz, with embedded caches and a Memory Management Unit for efficient program execution.
• On‑chip Memory and Bus Matrix Multiple embedded memories (including internal ROM and SRAM) and a nine 32-bit-layer bus matrix providing high internal bandwidth.
• External Memory Interfaces Two independent External Bus Interfaces (EBI0 and EBI1) supporting SDRAM, static memories and ECC-enabled NAND Flash; EBI0 also supports CompactFlash and IDE hard disk interfacing.
• Display and Graphics Integrated LCD controller supporting passive and active displays (up to 24 bits per pixel in TFT mode) and two 2D graphics accelerators for line draw, block transfer and clipping.
• Image Capture Image Sensor Interface with ITU‑R BT.601/656 external interface and a 12‑bit data path, including preview scaler and YCbCr support.
• Connectivity 10/100 Mbps Ethernet MAC with dedicated DMA channels and USB 2.0 Full Speed host (dual port) and device support with on‑chip transceivers and integrated FIFOs.
• Storage and Multimedia Multimedia Card interface and AC97 audio interface for multimedia and audio subsystem integration.
• DMA and Peripherals 2-channel DMA controller, 20 peripheral DMA controller channels (PDC), plus USART, SPI, TWI, timers, PWM generators and CAN controller.
• System and Debug EmbeddedICE debug support, Embedded Trace Macrocell, advanced interrupt controller, power management and battery-backed registers for system control.
• Package and Reliability 324‑TFBGA (15×15) surface-mount package and industrial operating temperature range of −40 °C to 85 °C. RoHS compliant.

Typical Applications

• Navigation Systems Integrated processing, display and peripheral support make it suitable for navigation units when combined with external GPS engines.
• Human‑Machine Interfaces (HMI) LCD controller and graphics accelerators enable responsive user interfaces for industrial control panels and information displays.
• Imaging and Vision Image Sensor Interface and scalable preview path support camera capture and image processing applications.
• Networked Embedded Devices 10/100 Mbps Ethernet and USB 2.0 ports provide connectivity for networked appliances, gateways and industrial controllers.
• Multimedia and Storage Subsystems Multimedia Card interface, AC97 audio and EBI support for NAND Flash and IDE storage enable multimedia-capable embedded systems.

Unique Advantages

• High on‑chip bandwidth: A nine-layer 32-bit bus matrix delivers substantial internal throughput to minimize bottlenecks between CPU, memory and peripherals.
• Dual external buses: Two independent EBIs let designers separate memory and storage traffic to sustain performance in complex systems.
• Integrated display and graphics: LCD controller plus two 2D accelerators reduce external graphics hardware needs and simplify HMI designs.
• Comprehensive I/O set: Ethernet, dual USB ports, CAN, MMC, AC97 and multiple serial interfaces provide flexible connectivity for varied embedded use cases.
• System‑level DMA and PDC: Dedicated DMA channels and peripheral DMA reduce CPU load for data movement, improving real‑time responsiveness.
• Industrial readiness: RoHS compliance and an operating range from −40 °C to 85 °C support deployments in industrial environments.
