• Memory Controllers Supports DDR2 and LPDDR external memory interfaces and 16-bit SDRAM configurations as described in the device family documentation.
• High-bandwidth Storage & Connectivity Integrated SATA 3 Gbps controller and 10/100 Mbps Ethernet physical layer for local storage and network connectivity.
• USB Subsystem USB 2.0 OTG/host/client functionality with an integrated PHY for straightforward USB connectivity.
• Peripheral Interfaces Multiple serial interfaces including I2C, SPI, UARTs, McBSP/McASP audio interfaces, multimedia card/SDIO channels and a universal parallel port for flexible peripheral connectivity.
• Video and Display LCD controller and video port interface (VPIF) support for display and capture use cases, including BT.656 and 8–16 bit video formats as outlined in the series documentation.
• Real-Time Subsystem (PRUSS) Programmable Real-Time Unit Subsystem with two PRU cores, on-chip instruction and data RAM for offloading low-latency control tasks.
• DMA and Timers Enhanced DMA (EDMA3) capabilities with multiple transfer controllers and numerous DMA channels, plus multiple general-purpose timers and a watchdog-capable timer.
• I/O and Power 1.8 V or 3.3 V LVCMOS I/Os (except USB and DDR2 interfaces) and on-chip system control coprocessor (CP15) for system management.
• Package and Temperature 361-ball NFBGA package (16 × 16 mm) and industrial operating temperature range of –40 °C to 90 °C.
• Compliance RoHS compliant.

Typical Applications

• Industrial Control — Real-time I/O handling and deterministic task offloading using the PRU subsystem, combined with wide temperature range suitability for industrial environments.
• Networked Embedded Systems — 10/100 Mbps Ethernet and USB 2.0 support enable connectivity for routers, gateways and edge devices.
• Storage-Enabled Appliances — Integrated SATA 3 Gbps and DDR2/LPDDR memory support for embedded storage controllers and multimedia record/playback systems.
• Human-Machine Interfaces (HMI) — LCD controller and video port interface assist in building display-driven panels and operator interfaces.

Unique Advantages

• Broad peripheral integration: Ethernet, SATA, USB with PHY, multiple serial interfaces and video/display controllers reduce external component count and simplify board-level design.
• Deterministic real-time capability: Programmable Real-Time Unit Subsystem (two PRU cores with on-chip RAM) provides low-latency control offload for time-sensitive tasks.
• Power and I/O flexibility: Support for 1.8 V or 3.3 V LVCMOS I/Os (per family documentation) enables interfacing with a wide range of peripherals and IO domains.
• High-throughput data movement: Enhanced DMA architecture with numerous channels and transfer controllers accelerates memory-to-peripheral transfers and reduces CPU load.
• Industrial temperature rating: Qualified for operation from –40 °C to 90 °C to meet extended-environment deployment requirements.
• Compact board footprint: 361-ball NFBGA (16 × 16 mm) package balances integration density with manufacturability for space-constrained embedded designs.
