OMAPL138BZWTD4E

The OMAPL138BZWTD4E is an embedded microprocessor built around an ARM926EJ-S 32-bit core running at 456 MHz and includes a TMS320C674x DSP coprocessor for signal-processing workloads. This combination delivers a balanced platform for designs that require control processing alongside high-performance DSP capabilities, with integrated memory controllers and a broad set of peripheral interfaces for embedded and industrial applications.

Designed for industrial-grade operation, the device integrates storage and connectivity interfaces, security features, and a compact 361-ball NFBGA package to support space-constrained systems that need both real-time signal processing and application control.

Key Features

• Core and DSP  ARM926EJ-S 32-bit core at 456 MHz with a TMS320C674x DSP coprocessor for mixed control and signal-processing tasks.
• Memory Architecture  Multiple on-chip memories and caches: ARM-side instruction and data caches and ROM; DSP-side 32KB L1P/L1D and 256KB L2 unified RAM/cache plus 128KB shared RAM, enabling flexible partitioning and low-latency data paths.
• DMA and Peripheral Offload  Enhanced EDMA3 controller with 64 independent channels, 3 transfer controllers and programmable bursts to accelerate data movement and reduce CPU/DSP load.
• Interfaces and Connectivity  Integrated 10/100 Mbps Ethernet, SATA 3 Gbps, USB 1.1 and USB 2.0 with PHYs, LCD display controller and HPI interface for broad I/O connectivity.
• External Memory Support  Two external memory interfaces (EMIFA and DDR2/Mobile DDR controllers) and SDRAM controller support, enabling NOR/NAND and DDR2 memory configurations.
• Security and Boot  Boot security and cryptography features to support secure system startup and protected operations.
• Software Ecosystem  Device is supported by TI software resources including DSP/BIOS, Chip Support Library and DSP libraries to accelerate development.
• Package and Temperature  361-ball NFBGA (16 × 16 mm) surface-mount package rated for industrial temperature operation from −40 °C to 90 °C.
• Standards and Compliance  RoHS-compliant manufacturing status.

Typical Applications

• Industrial Control  Use the ARM core for control and system management while the C674x DSP processes sensor data, filtering and analytics in industrial automation systems.
• Communications and Networking  Integrated Ethernet, USB and DMA support enable embedded networking equipment and protocol offload functions.
• Storage and Media Subsystems  SATA 3 Gbps together with USB and DMA capabilities make the device suitable for embedded storage controllers and media appliances.
• Human-Machine Interfaces  LCD controller and rich I/O support enable responsive operator interfaces and display-driven embedded systems.

Unique Advantages

• Combined Control and DSP Processing: ARM926EJ-S core plus C674x DSP coprocessor provide both control-plane responsiveness and high-performance signal processing without separate chips.
• Flexible Memory and Cache Configuration: Multiple levels of cache and configurable L1/L2 partitioning improve real-time performance and let designers tune memory for application needs.
• Comprehensive Peripheral Set: On-chip Ethernet, SATA, USB 1.1/2.0 with PHYs and display/HPI interfaces reduce external components and simplify board-level design.
• High-Bandwidth Data Movement: EDMA3 controller with up to 64 channels and programmable bursts minimizes CPU/DSP overhead for large-data transfers.
• Industrial Readiness: Rated for −40 °C to 90 °C operation and supplied in a compact 361-NFBGA package suitable for space-constrained, rugged systems.
• Development Support: TI-provided software libraries and DSP/BIOS support accelerate bring-up and algorithm deployment.
