Detailed Description

Low-power dual-core processor combining an ARM926EJ-S (ARM9) application core with a TMS320C674x floating‑point DSP core. Designed for embedded control, industrial, audio, and communication systems that need real-time signal processing with general-purpose application control. Integrates rich peripherals for external memory, connectivity, audio, and display, enabling compact designs with reduced BOM and board complexity.

Key Features

Dual-core architecture: ARM9 for application/UI and C674x DSP for real-time signal processing

External memory interfaces: DDR2/LPDDR, SDRAM, NAND, NOR, asynchronous memories

Connectivity: 10/100 Ethernet MAC, USB 2.0 OTG/Host/Device, UARTs, SPI, I2C

Audio and timing: McASP multi-channel audio serial ports, enhanced timers, RTC

Storage and media: MMC/SD interface, LCD controller for simple display systems

DMA: EDMA3 controller for efficient data movement

System control: AINTC interrupt controller, GPIO, PLLs, power management features

Industrial-grade integration: Suited for long-life embedded deployments

Key Advantages

Flexible performance partitioning: Run OS and application code on ARM while offloading math-intensive tasks to DSP

High integration reduces component count, PCB area, and development complexity

Mature TI ecosystem: robust tools, libraries, and long-term product support

Broad interface set supports fast design reuse across multiple product lines

Low power operation and sleep options help meet tight thermal and energy budgets

Packaging

Component package: Plastic BGA (ZWT family), lead-free, RoHS compliant

Ball count and pitch: 361 balls, 0.8 mm pitch (typical for ZWT package)

Body size: approximately 16 mm × 16 mm (typical for ZWT PBGA)

Pin configuration: 19 × 19 ball grid; organized into banks for memory, I/O, and power (see datasheet ball map)

Thermal characteristics: typical ThetaJA ~25–35 °C/W (board-dependent), ThetaJC ~8–10 °C/W (reference values; confirm in datasheet for your layout)

Electrical supplies (typical): core ~1.2 V; I/O rails 3.3 V and 1.8 V; DDR2 interface at 1.8 V; dedicated analog/PLL rails (see datasheet for exact rails and tolerances)

Moisture sensitivity: MSL 3 (typical for PBGA); dry pack; bake required if floor life is exceeded

Shipping form: tray packaging for BGA devices

Inventory lot details: Quantity 1405 units available; Date Code 1423+ (contact us for exact lot and traceability)

Lifecycle
