• Multimedia and Sensor Interfaces Image sensor interface compatible with ITU-R BT.601/656, AC'97 audio controller and multiple synchronous serial controllers (I2S mode) for audio and camera integration.
• Peripheral Mix Multiple USARTs (with ISO7816, IrDA, Manchester, SPI modes), SPI, two-wire interfaces, PWM channels, timers, and an 8-channel 10-bit ADC with 4-wire touch-screen support for diverse I/O needs.
• System and Performance 133 MHz multi-layer AHB bus matrix, 37 DMA channels and dual PLLs (including a 480 MHz PLL optimized for USB) to sustain high data throughput for peripherals and memory.
• Power Management On-chip power management controller with efficient clock gating and a battery backup section to reduce power consumption in active and standby modes.
• Industrial Grade Packaging and Temperature 324-ball TFBGA (15×15, 0.8 mm pitch) surface-mount package and an operating temperature range of −40 °C to 85 °C for industrial environments.
• Mounting and Compliance Surface-mount device with RoHS compliance for modern PCB assembly and environmental requirements.

Typical Applications

• Human-Machine Interfaces (HMIs) — Drives TFT/STN displays with resistive touch support for control panels, kiosks and industrial operator interfaces.
• Embedded Networking Appliances — 10/100 Mbps Ethernet and USB host/device capabilities for networked controllers, gateways and edge devices.
• Imaging and Multimedia Devices — Camera interface, AC'97 audio and synchronous serial controllers enable compact multimedia and vision-enabled products.
• Storage and Data Loggers — DDR2/LPDDR support and NAND/SDIO hosts facilitate local storage, SD card boot and high-rate data logging applications.
• Industrial Control Systems — Wide temperature range, robust I/O mix and PWM/timers make the device suitable for factory automation and instrumentation.

Unique Advantages

• Highly integrated connectivity: On-chip Ethernet MAC, multi-role USB, SDIO/SD card hosts and AC'97 reduce external components and simplify board-level integration.
