• System architecture  133 MHz multi-layer AHB bus matrix, 39 DMA channels and dual external bus interfaces to sustain high peripheral and memory throughput.
• Multimedia & display  On‑chip LCD controller, resistive touchscreen support, camera interface and a hardware video decoder with image post‑processing (scaling, color conversion, rotation) supporting common codecs.
• Connectivity  Integrated 10/100 Mbps Ethernet and three USB 2.0 ports plus SDIO support for flexible wired and removable storage connectivity.
• Audio & legacy I/O  On‑chip audio interfaces and AC97 support for audio subsystem integration.
• Security  On‑chip cryptographic accelerators with support for up to 256‑bit AES, TDES (FIPS PUB 46‑3), SHA1/SHA256 (FIPS 180‑2) and an embedded True Random Number Generator for secure key generation.
• Power management & low power modes  Software‑selectable Idle, Ultra Low‑power and Backup modes, clock gating and a battery backup section to minimize active and standby consumption.
• Voltage & I/O flexibility  I/Os support independently configurable 1.8 V or 3.3 V operation for memory and peripherals, reducing the need for external level shifting.
• Package & temperature  324‑TFBGA (15×15) surface‑mount package with support for 0.8 mm ball pitch PCB assembly; industrial operating range −40 °C to 85 °C.

Typical Applications

• Media‑rich displays and control panels  Hardware video decode, LCD and touchscreen support enable smooth playback and responsive user interfaces for building automation and commercial panels.
• Point‑of‑sale (POS) terminals  Integrated Ethernet, multiple USB ports and secure cryptographic accelerators support connected payment and peripheral I/O in POS systems.
• Entertainment systems  Video decoder and image post‑processing provide the multimedia building blocks for consumer and commercial entertainment devices.
• Internet appliances and gateways  10/100 Ethernet, SDIO and multiple USB ports make the device suitable for connected appliances and networked interfaces.
• Medical and industrial control  Industrial temperature grade, low‑power modes and robust memory interfaces suit control panels and instrumentation requiring long‑term reliability.

Unique Advantages

• Integrated multimedia engine: On‑chip video decoding and image post‑processing reduce external component count and offload CPU cycles for smoother media playback.
• Flexible memory support: DDR2/LPDDR controller plus NAND/SD boot options simplify system design and offer multiple storage choices for program and data.
• Hardware security acceleration: AES/TDES and SHA engines with TRNG provide on‑chip cryptographic performance for secure communications and storage without taxing the main core.
• Rich connectivity: Multiple USB 2.0 ports and 10/100 Ethernet enable diverse peripheral and network configurations out of the box.
• Industrial readiness: Surface‑mount 324‑TFBGA packaging, 0.8 mm ball pitch support and −40 °C to 85 °C operation address industrial manufacturing and environmental requirements.
• Power and boot flexibility: Multiple low‑power modes, clock gating and support for boot from NAND, SDCard or DataFlash help optimize power and system-level design.
