This architecture lets a single chip handle both control-plane tasks and real-time signal processing — motor control loops, audio encoding, vibration analysis, or protocol bridging — without a separate DSP or FPGA. On-chip peripherals include USB 1.1 and USB 2.0 each with integrated PHY, a SATA 3 Gbps port, and a 10/100 Mbps Ethernet MAC, so the part can serve as a system hub in industrial gateways, human-machine interfaces, or data-acquisition nodes. The LCD controller drives a local display directly, and the memory interface supports SDRAM, keeping BOM cost predictable. ## Temperature grade and deployment environment Rated for -40°C to 105°C junction temperature, this part is suited for factory-floor automation, outdoor telecom cabinets, and engine-adjacent electronics where commercial-grade parts would drift or latch. The 361-NFBGA package (16x16 mm) requires controlled reflow and X-ray inspection — standard for a BGA of this density, but worth factoring into assembly yield planning if your line is used to QFPs. ## Supply voltage and I/O flexibility The I/O voltage is configurable at 1.8 V or 3.3 V, which means the OMAPL138EZWTA3 can interface directly with legacy 3.3 V peripherals (serial Flash, UART transceivers, sensors) or switch to 1.8 V for lower-power memory interfaces. The core voltage is derived from an internal regulator; the board design needs the appropriate supply rails for each I/O bank. Additional interfaces include HPI, I²C, McASP, McBSP, MMC/SD, SPI, and UART, covering most industrial communication buses without external level shifters. ## Security and boot options Boot security and cryptography features are built in, allowing encrypted firmware storage and authenticated boot — relevant if the end product needs to resist cloning or tampering in field-deployed equipment. The system-control coprocessor handles memory management and cache coherency between the ARM and DSP cores. ## Lifecycle and sourcing posture That means no last-time-buy scramble and no forced redesign for a replacement. For a BOM line that needs this specific dual-core MPU, the supply channel is open and the risk of sudden obsolescence is low.","metaTitle":"TI OMAPL138EZWTA3 ARM926EJ-S + C674x DSP, 375MHz, 361-NFBGA","metaDescription":"Texas Instruments OMAPL138EZWTA3 dual-core processor: ARM926EJ-S at 375MHz, C674x DSP, USB 1.1 & 2.0, SATA 3Gbps, Ethernet 10/100, -40 to 105°C.","metaKeywords":null},"attributes":{"series":"OMAP-L1x","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"USB":"USB 1.1 + PHY (1), USB 2.0 + PHY (1)","SATA":"SATA 3Gbps (1)","Speed":"375MHz","Series":"OMAP-L1x","Package":"Tray","Ethernet":"10/100Mbps (1)","Mounting Type":"Surface Mount","Voltage - I/O":"1.8V, 3.3V","Core Processor":"ARM926EJ-S","Package / Case":"361-LFBGA","RAM Controllers":"SDRAM","lifecycle_stage":"eol_hot","Co-Processors/DSP":"Signal Processing; C674x, System Control; CP15","Security Features":"Boot Security, Cryptography","Additional Interfaces":"HPI, I²C, McASP, McBSP, MMC/SD, SPI, UART","Graphics Acceleration":"No","Operating Temperature":"-40°C ~ 105°C (TJ)","Supplier Device Package":"361-NFBGA (16x16)","Number of Cores/Bus Width":"1 Core, 32-Bit","Display & Interface Controllers":"LCD"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$53.25","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$53.25000","currency":"USD"},{"qty":10,"price":"$49.67900","currency":"USD"},{"qty":25,"price":"$47.59680","currency":"USD"},{"qty":90,"price":"$43.13456","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/23ec7ced3c2b01627c6720417460b0e1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum speed of the OMAPL138EZWTA3?","answer":"The OMAPL138EZWTA3 is rated at 375 MHz, which applies to both the ARM926EJ-S core and the C674x DSP.
