• Bus and DMA  133 MHz multi-layer AHB bus architecture with 39 DMA channels to sustain high peripheral and memory bandwidth.
• Display and Imaging  Integrated LCD controller supporting STN and TFT displays up to 1280×860 and ITU-R BT.601/656 image sensor interface (ISI) for camera input and touchscreen support.
• Connectivity  10/100 Mbps Ethernet MAC and three USB 2.0 controllers (dual host and one device) plus SDIO/SDCard/e.MMC hosts for high-speed data transfer and storage expansion.
• Audio and Legacy Interfaces  AC’97 controller and I2S-capable synchronous serial controllers for audio and codec connectivity.
• Security Accelerators  On-chip AES (up to 256-bit), TDES and SHA1/SHA256 accelerators, plus a True Random Number Generator (TRNG) for cryptographic key generation and secure protocols.
• Peripheral Mix  Multiple USARTs, SPI, TWI (I2C), timers, PWM channels, and an 8-channel 10-bit ADC with 4-wire touchscreen support for mixed-signal and control applications.
• Boot and Storage Options  Flexible boot from NAND Flash, SDCard, DataFlash or serial DataFlash with on-chip ECC support for SLC NAND.
• Industrial Grade and Packaging  Industrial temperature rating (-40 °C to 85 °C) in a 324-TFBGA (15×15) package suitable for surface-mount assembly.

Typical Applications

• Industrial Control Panels  Use the integrated LCD controller, touchscreen support and robust I/O mix to implement operator interfaces and machine control displays.
• Networked Gateways and Embedded Networking  Combine the 10/100 Mbps Ethernet MAC, multiple USB ports and SDIO hosts for local storage and network connectivity in gateway devices.
• Multimedia and Imaging Devices  Leverage the ISI camera interface, LCD controller and audio peripherals for imaging terminals, handheld inspection tools or kiosks.
• Secure Data Processing  On-chip cryptographic accelerators and TRNG enable secure storage, authentication and encrypted communications for industrial and enterprise embedded systems.

Unique Advantages

• High integration: Processor core, display, camera, Ethernet, USB and memory controllers on a single device reduce BOM and simplify board design.
• Flexible memory support: Native DDR2, LPDDR, SDR and static memory interfaces accommodate a range of storage and performance requirements.
• Hardware cryptography: Built-in AES, TDES, SHA and TRNG accelerate secure operations while offloading the CPU.
• Deterministic memory access: 64 KB TCM-configurable SRAM and a multi-layer AHB bus with numerous DMA channels optimize real-time and high-throughput data paths.
• Industrial temperature rating: Specified operation from -40 °C to 85 °C supports deployment in industrial environments.
• Compact, manufacturable package: 324-TFBGA (15×15) with 0.8 mm ball pitch supports cost-effective PCB assembly.
