AM3892BCYG150 Equivalent & Substitute Parts

Part Overview

The AM3892BCYG150 is an ARM® Cortex®-A8 Microprocessor IC from Texas Instruments' Sitara™ series, featuring a single 32-bit core operating at 1.5GHz in a 1031-FCBGA (25x25) package. This processor integrates multimedia co-processing with NEON™ SIMD capabilities, dual Gigabit Ethernet ports, SATA 3Gbps interface, and dual USB 2.0 ports with PHY. The device is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring similar performance characteristics.

Substitute Part Grouping Explanation

Substitution of the AM3892BCYG150 is determined by strict equivalence across the following critical parameters:

Core Architecture & Processing: Identical ARM® Cortex®-A8 core processor, 1 core, 32-bit configuration, and Sitara™ series membership ensure functional compatibility at the instruction set and software level.

Memory & Co-Processing: Identical DDR2/DDR3 RAM controller support and NEON™ SIMD multimedia co-processor ensure equivalent data handling and multimedia processing capabilities.

Interface & Connectivity: Identical Ethernet (10/100/1000Mbps dual ports), SATA 3Gbps, USB 2.0 + PHY (dual ports), and supplementary interfaces (I2C, McASP, McBSP, SPI, SD/SDIO, UART) ensure pin-level and functional compatibility.

Physical & Environmental: Identical 1031-FCBGA (25x25) package, 1.8V/3.3V I/O voltage, 0°C ~ 95°C operating temperature range, and MSL 4 rating ensure mechanical fit and environmental performance equivalence.

Regulatory Compliance: Identical ROHS3 compliance and REACH unaffected status ensure regulatory alignment.

Variable Parameter: Operating frequency (1.5GHz vs. 1.35GHz) represents the only technical variance. The substitute part operates at a lower frequency, which does not preclude substitution in applications where the lower speed is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The AM3892CCYG135 is a direct functional equivalent to the AM3892BCYG150 across all critical electrical, mechanical, and interface parameters. The substitute part maintains identical core architecture, peripheral integration, package footprint, and regulatory compliance status.

The primary distinction is operating frequency: the substitute operates at 1.35GHz versus the original 1.5GHz. This frequency reduction does not affect instruction set compatibility, peripheral functionality, or physical integration. Selection of the substitute is appropriate for applications where the lower clock speed meets performance requirements.

The AM3892CCYG135 carries active product status from Texas Instruments, ensuring ongoing availability and supply chain continuity. The original AM3892BCYG150 is classified as obsolete, making the substitute the recommended choice for new designs and ongoing system support requiring Sitara™ ARM® Cortex®-A8 single-core 32-bit processing with integrated multimedia, networking, and storage interfaces.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the AM3892CCYG135 be used as a direct replacement for the AM3892BCYG150 in existing designs?

A: Yes. The substitute part is electrically and mechanically equivalent across all interface definitions, pin assignments, voltage requirements, and package dimensions. The 1031-FCBGA (25x25) footprint is identical, and all peripheral interfaces (Ethernet, SATA, USB, display controllers, and supplementary I/O) are functionally equivalent. The lower operating frequency does not affect compatibility at the hardware integration level.

Q: What is the impact of the 1.35GHz versus 1.5GHz frequency difference?

A: The frequency difference affects computational throughput. Applications requiring the full 1.5GHz performance must evaluate whether 1.35GHz meets their processing requirements. For applications with timing-critical operations or high-performance computing demands, the frequency reduction may impact system performance. For general-purpose embedded applications, the lower frequency typically does not present a functional barrier.

Q: Are the package and pinout identical between these parts?

A: Yes. Both parts use the 1031-FCBGA (25x25) package with identical pin assignments, mechanical dimensions, and thermal characteristics. PCB layout and footprint definitions are interchangeable.

Q: Why is the AM3892BCYG150 obsolete while the AM3892CCYG135 remains active?

A: Product lifecycle management by Texas Instruments has transitioned the higher-frequency variant to obsolescence while maintaining production of the lower-frequency variant. This is a common industry practice where lower-performance variants often have extended production lifecycles due to broader application compatibility and lower power consumption characteristics.

Q: Are there any differences in power consumption between these parts?

A: Power consumption data is not provided in the available specifications. The lower operating frequency of the AM3892CCYG135 typically results in reduced dynamic power consumption compared to the 1.5GHz variant, though this relationship is not explicitly documented in the provided parameters.

Q: Do both parts support identical memory configurations?

A: Yes. Both parts include identical DDR2 and DDR3 RAM controllers, supporting equivalent memory configurations and bandwidth characteristics at the controller level.

Q: Are the thermal and environmental operating ranges identical?

A: Yes. Both parts operate across the 0°C to 95°C (TJ) temperature range and maintain MSL 4 moisture sensitivity rating with 72-hour exposure limits. Thermal management requirements are equivalent.
