AM3874BCYE80 Equivalent & Substitute Parts

Part Overview

The AM3874BCYE80 is an ARM® Cortex®-A8 Microprocessor IC from Texas Instruments' Sitara™ series, featuring a single 32-bit core operating at 80MHz with integrated multimedia and NEON™ SIMD co-processors. This device is housed in a 684-FCBGA (23x23) package and includes DDR2/DDR3 RAM controllers, graphics acceleration, and multiple interface controllers including HDMI and HDVPSS.

The AM3874BCYE80 is classified as Obsolete. Identifying equivalent substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM3874BCYE80 is determined by strict equivalence across the following critical parameters:

Core Architecture & Processing Capability: The substitute must feature an ARM® Cortex®-A8 core with 1 core, 32-bit configuration and identical co-processor support (Multimedia and NEON™ SIMD).

Memory & Interface Support: The substitute must support DDR2 and DDR3 RAM controllers, graphics acceleration, and the complete set of display and interface controllers (HDMI, HDVPSS).

Connectivity & Peripheral Interfaces: The substitute must provide 10/100/1000Mbps Ethernet (1 port), SATA 3Gbps (1 port), USB 2.0 (2 ports), and all additional interfaces (CAN, I2C, McASP, McBSP, SPI, MMC/SD/SDIO, UART).

Package & Environmental Compliance: The substitute must use the 684-FCBGA (23x23) package, maintain the same voltage I/O levels (1.8V, 3.3V), operating temperature range (0°C ~ 90°C TJ), and meet ROHS3 compliance and MSL 4 requirements.

Speed Variance: While the AM3874BCYE80 operates at 80MHz, the substitute AM3874CCYE80 operates at 800MHz. This higher speed maintains full backward compatibility and functional equivalence while providing enhanced performance headroom.

Parameter Comparison

Engineering Selection Recommendations

The AM3874CCYE80 is the direct substitute for the AM3874BCYE80. Both devices share identical architectural specifications, package form factor, and compliance certifications (ROHS3, MSL 4). The AM3874CCYE80 maintains Active product status with significantly higher inventory availability (23,846 pcs vs. 1,043 pcs), ensuring long-term supply chain reliability.

The primary distinction is the operating frequency: AM3874CCYE80 operates at 800MHz compared to the AM3874BCYE80 at 80MHz. This speed increase provides enhanced computational performance while maintaining full functional and pin-level compatibility. The higher speed does not introduce any electrical or thermal incompatibilities within the specified operating temperature range (0°C ~ 90°C TJ).

For new designs or system updates, the AM3874CCYE80 is the preferred selection due to its Active status and superior availability. For legacy system maintenance requiring exact performance matching, the AM3874BCYE80 remains the original specification, though procurement may be constrained due to Obsolete classification.

Frequently Asked Questions (FAQ)

Q: Can the AM3874CCYE80 directly replace the AM3874BCYE80 in existing designs?

A: Yes. Both devices use the 684-FCBGA (23x23) package with identical pinout and electrical specifications. The AM3874CCYE80 operates at 800MHz versus 80MHz, providing enhanced performance without requiring circuit modifications.

Q: Are there any voltage or thermal considerations when substituting these parts?

A: No. Both parts maintain identical I/O voltage levels (1.8V, 3.3V) and operating temperature range (0°C ~ 90°C TJ). Thermal and electrical characteristics remain equivalent.

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

A: The AM3874BCYE80 is classified as Obsolete, indicating Texas Instruments has discontinued active production and support. The AM3874CCYE80 is Active, meaning it remains in production with ongoing manufacturer support and significantly higher inventory availability.

Q: Are the interface and peripheral capabilities identical between these parts?

A: Yes. Both devices provide identical support for DDR2/DDR3 memory controllers, graphics acceleration, HDMI/HDVPSS display controllers, 10/100/1000Mbps Ethernet, SATA 3Gbps, USB 2.0, and all additional interfaces (CAN, I2C, McASP, McBSP, SPI, MMC/SD/SDIO, UART).

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the AM3874BCYE80 and AM3874CCYE80 are ROHS3 compliant with MSL 4 (72 Hours) moisture sensitivity rating. REACH and ECCN classifications are identical.
