OMAPL137BZKB4 Equivalent & Substitute Parts

Part Overview

The OMAPL137BZKB4 is an ARM926EJ-S Microprocessor IC from the OMAP-L1x series manufactured by Texas Instruments. This 32-bit, single-core processor operates at 456MHz and integrates signal processing capabilities via the C674x DSP co-processor. The device features comprehensive connectivity including 10/100Mbps Ethernet, USB 1.1 and USB 2.0 interfaces, LCD controller, and multiple serial interfaces (UART, SPI, I2C, McASP, MMC/SD). Currently marked as obsolete, the OMAPL137BZKB4 requires identification of active equivalent parts to support ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OMAPL137BZKB4 is determined by strict equivalence across the following critical parameters:

• Processor Architecture & Performance: ARM926EJ-S core, 456MHz clock speed, and C674x DSP co-processor must remain identical
• Package Specification: 256-BGA (17x17) form factor ensures mechanical and electrical compatibility with existing PCB layouts
• Electrical Characteristics: I/O voltage levels (1.8V, 3.3V) and operating temperature range (0°C ~ 90°C) must match
• Interface Completeness: All integrated peripherals including Ethernet, USB, LCD controller, and serial interfaces must be present
• Compliance & Certification: RoHS3 compliance and MSL rating must be maintained

The OMAPL137DZKB4 qualifies as a direct substitute based on identical electrical specifications, package geometry, and functional integration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The OMAPL137DZKB4 is the direct functional equivalent of the OMAPL137BZKB4. Both devices share identical electrical specifications, processor architecture, clock frequency, DSP capabilities, and package geometry. The OMAPL137DZKB4 is currently in active production status, whereas the OMAPL137BZKB4 is obsolete.

For new designs and ongoing system support, the OMAPL137DZKB4 is the appropriate selection. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with current manufacturing and storage requirements. The packaging format difference (tray versus unspecified for the original) does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the OMAPL137DZKB4 directly replace the OMAPL137BZKB4 in existing designs?

A: Yes. The OMAPL137DZKB4 is electrically and mechanically identical to the OMAPL137BZKB4. Both devices feature the same ARM926EJ-S processor, 456MHz clock speed, C674x DSP co-processor, 256-BGA package, I/O voltage levels, and operating temperature range. No PCB modifications or firmware changes are required.

Q: What is the significance of the product status difference?

A: The OMAPL137BZKB4 is marked as obsolete, indicating Texas Instruments has discontinued production. The OMAPL137DZKB4 is in active production status, ensuring availability for procurement and long-term supply chain stability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the OMAPL137BZKB4 and OMAPL137DZKB4 maintain identical RoHS3 compliance, MSL rating of 3 (168 Hours), REACH status, and ECCN/HTSUS classifications.

Q: Does the packaging format (tray) affect compatibility?

A: No. Packaging format refers to the shipping and storage container and does not affect the electrical or mechanical properties of the component itself. The die, package geometry, and pin configuration remain identical.

Q: What interfaces are available on both parts?

A: Both devices include HPI, I2C, McASP, MMC/SD, SPI, and UART interfaces, along with 10/100Mbps Ethernet, USB 1.1 and USB 2.0 connectivity, and LCD controller functionality.
