OMAPL137CZKB4 Equivalent & Substitute Parts

Part Overview

The OMAPL137CZKB4 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, system control via CP15, and comprehensive peripheral interfaces including Ethernet, USB, LCD, and audio interfaces. The device is packaged in a 256-BGA (17x17) form factor with surface mount configuration.

The OMAPL137CZKB4 carries an Obsolete product status, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and production continuity. Substitute parts must maintain identical electrical specifications, core architecture, and interface compatibility to ensure drop-in replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OMAPL137CZKB4 is determined by strict equivalence across the following critical parameters:

• Core Architecture: ARM926EJ-S processor with identical instruction set and performance characteristics
• Clock Speed: 456MHz operation
• DSP Co-Processor: C674x signal processing capability
• System Control: CP15 system control coprocessor
• Memory Interface: SDRAM controller support
• Peripheral Set: Identical Ethernet (10/100Mbps), USB (1.1 and 2.0), LCD, HPI, I2C, McASP, MMC/SD, SPI, and UART interfaces
• Voltage Levels: 1.8V and 3.3V I/O compatibility
• Package: 256-BGA (17x17) surface mount configuration
• Thermal Range: 0°C to 90°C junction temperature
• Compliance: ROHS3 and REACH compliance status

The OMAPL137DZKB4 meets all substitution criteria as a direct equivalent within the OMAP-L1x product family.

Parameter Comparison

Engineering Selection Recommendations

The OMAPL137DZKB4 is a direct functional equivalent to the OMAPL137CZKB4 with identical electrical, architectural, and interface specifications. The primary distinction is product lifecycle status: the OMAPL137CZKB4 is classified as Obsolete, while the OMAPL137DZKB4 maintains Active status with Texas Instruments.

Selection of the OMAPL137DZKB4 is supported by:

• Complete parameter equivalence across all electrical and functional specifications
• Identical 256-BGA (17x17) package configuration ensuring PCB layout compatibility
• Matching ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements
• Active product status providing access to current manufacturing, technical support, and supply chain continuity
• Identical MSL rating (3, 168 Hours) and thermal operating range

For applications currently utilizing the OMAPL137CZKB4, transition to the OMAPL137DZKB4 requires no design modifications, as all pin assignments, electrical characteristics, and interface protocols remain unchanged.
