OMAPL138EZWTQ4

The OMAPL138EZWTQ4 from Texas Instruments is a 32‑bit ARM926EJ‑S microprocessor running at 456 MHz in a 361‑NFBGA (16×16) surface‑mount package. It is targeted at embedded applications that require a combination of general‑purpose processing, signal‑processing support and a broad set of memory and peripheral interfaces.

Designed for embedded system designs, the OMAP‑L13x family provides integrated connectivity and storage interfaces (Ethernet, SATA, USB), memory controller support and security features—helping reduce system complexity and BOM count for networking, storage and industrial applications.

Key Features

• Core and Architecture ARM926EJ‑S 32‑bit processor core operating at 456 MHz; specified as a single 32‑bit core for this device. Co‑processor support includes a C674x signal‑processing engine and CP15 system control blocks per product data.
• Memory and Cache Support Onboard support for DDR2 and LPDDR memory controllers; datasheet series material documents multi‑level cache and shared RAM architectures used across the OMAP‑L13x family to support high throughput data movement.
• Storage and Connectivity Integrated interfaces include 10/100 Mbps Ethernet (1), SATA 3 Gbps (1) and both USB 1.1 + PHY and USB 2.0 + PHY, enabling networked and storage‑centric embedded designs.
• Display and Host Interfaces LCD controller support and additional host processor interface (HPI) allow direct connection to displays and host processors for user interfaces and inter‑processor communication.
• Peripheral and Serial Interfaces Multiple serial interfaces and peripheral controllers are available across the OMAP‑L13x series (datasheet details include UARTs, SPI and other peripheral connectivity options).
• Security Built‑in boot security and cryptography features provide foundational platform security for secure boot and data protection functions.
• Package and Mounting Supplied in a 361‑NFBGA (16×16) package, surface‑mount mounting type; RoHS compliant for environmental compliance.
• DMA and System Support (series‑level) Series documentation highlights an enhanced EDMA3 controller and flexible memory/interface blocks to accelerate data transfers and simplify real‑time data handling in embedded applications.

Typical Applications

• Embedded Networking and Gateways — Use the integrated Ethernet and USB interfaces along with on‑chip processing to implement protocol handling and gateway functions.
• Storage and NAS Devices — SATA 3 Gbps support combined with DMA capabilities makes the device suitable for small storage controllers and networked storage appliances.
• Human‑Machine Interfaces (HMI) — LCD controller support and host interface options enable development of embedded HMIs and operator panels.
• Signal Processing and Instrumentation — C674x signal‑processing capabilities (as documented in the OMAP‑L13x series) allow acceleration of compute‑intensive signal tasks alongside the ARM host core.

Unique Advantages

• Integrated Connectivity: Combines Ethernet, SATA and USB interfaces to reduce external controllers and simplify board design.
• Processor plus Signal‑Processing Support: ARM926EJ‑S host core with C674x signal‑processing co‑processor support enables mixed workloads without adding discrete DSP chips.
• Flexible Memory Options: DDR2 and LPDDR memory controller support allows designers to choose memory configurations that match performance and cost targets.
• Security Foundations: Built‑in boot security and cryptography features provide a platform for secure system boot and data protection.
• Compact, Manufacturable Package: 361‑NFBGA (16×16) surface‑mount package supports high‑density board layouts and automated assembly.
• RoHS Compliant: Conforms to RoHS requirements to support environmental and regulatory goals.
