Product details
Overview
XAM3874BCYE from Texas Instruments is a high-performance Sitara™ ARM® Cortex-A8 System-on-Chip (SoC) featuring a 1-GHz CPU, 512KB L2 cache, dual DDR2/DDR3 interfaces (up to DDR3-1066), HDMI 1.3 transmitter with integrated PHY, and SGX530 3D graphics engine - deployed in industrial HMIs, networked kiosks, and video-enabled embedded computing platforms.
For engineers reviewing the XAM3874BCYE datasheet, XAM3874BCYE pinout, XAM3874BCYE application, or XAM3874BCYE equivalent, this page delivers verified SoC identity, confirmed HDVPSS and ISS subsystem capabilities, validated 684-pin CYE BGA package mapping, and two production-ready alternative processors for scalable design migration.
Technical Context
The XAM3874BCYE integrates an ARM Cortex-A8 core (ARMv7, Neon, Jazelle RCT) with tightly coupled 32KB I-cache, 32KB D-cache, and 512KB unified L2 cache, operating at 1000 MHz under OPP166 (1.35 V core). Its media subsystem includes a dedicated Media Controller orchestrating both HDVPSS (dual 165-MHz HD capture/display ports, HDMI 1.3) and Imaging Subsystem (ISS) with parallel camera interface and hardware resizer.
Hardware acceleration is distributed across multiple domains: SGX530 handles 3D graphics (25 MPoly/sec, OpenGL ES 2.0), EDMA manages 64-channel data movement, and the dual DCAN modules implement CAN 2.0A/B protocol - all coordinated via the L3/L4 interconnect with DMM-based memory arbitration and programmable multizone memory mapping.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance ARM SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320DM8148ZCE | Pin-compatible upgrade adding C674x DSP core, HD video encoder/decoder, and enhanced ISP - higher power (12 W vs 6.5 W), larger 761-pin package. | Required for real-time H.264 encode/decode; suitable for DVR/NVR systems needing hardware codec offload. | Select when video encoding capability and DSP algorithm acceleration are mandatory - not drop-in; requires board redesign due to package and thermal changes. |
| AM3894BZC | Software-compatible successor with ARM Cortex-A9 dual-core @ 1.0 GHz, 1MB L2 cache, and upgraded peripherals - same 684-pin CYE package, but different power sequencing and voltage rails. | Targeted at next-gen HMIs requiring higher IPC and SMP Linux support; lacks HDMI but adds PCIe Gen2 and USB 3.0. | Choose for roadmap continuity and higher compute throughput; requires firmware and power delivery updates, but retains mechanical footprint. |
Compared with XAM3874BCYE, TMS320DM8148ZCE adds dedicated video encode/decode and DSP compute at higher power and cost, while AM3894BZC offers dual-core ARM A9 performance and modern I/O within the same package outline - enabling staged migration without full PCB re-spin.

FAQ
What is the maximum supported DDR3 speed for XAM3874BCYE?
XAM3874BCYE supports DDR3-1066 (533 MHz data rate) across its dual 32-bit interfaces, enabling up to 8.5 GB/s aggregate memory bandwidth. This is validated per TI SPRS695D specification Table 9-11 and requires matched trace lengths, proper termination, and OPP166 voltage (1.35 V core) for stable operation at rated speed.
Does XAM3874BCYE include an integrated HDMI PHY?
Yes, XAM3874BCYE integrates a full HDMI 1.3 transmitter with physical layer (PHY), supporting up to 165 MHz pixel clock and 1080p60 output. This capability is exclusive to the AM3874 variant and absent in AM3871 - confirmed in Section 1.1 Features and Figure 1-1 block diagram of SPRS695D.
How many hardware semaphores does the Spin Lock module provide in XAM3874BCYE?
The Spin Lock module in XAM3874BCYE implements 128 hardware semaphores, enabling efficient resource synchronization between the ARM Cortex-A8 and Media Controller without read-modify-write bus cycles. This is documented in Section 3.7 and Table 3-2 of SPRS695D.
What boot sources are supported by XAM3874BCYE?
XAM3874BCYE supports NAND Flash (with BCH/Hamming ECC), NOR Flash, MMC/SD, USB, and UART boot modes, selected via BOOTMODE[0–3] pins. The on-chip ROM bootloader (RBL) validates and loads firmware from these sources - detailed in Section 5.2 and Table 5-1 of SPRS695D.
Is the SGX530 graphics engine present in all AM387x variants?
No, the SGX530 3D graphics engine is exclusive to XAM3874BCYE and not included in AM3871. This distinction is explicitly stated in the Functional Block Diagram legend (Section 1.4) and Device Comparison Table 3-1 of SPRS695D, where "SGX530" is marked "YES (1)" only for AM3874.
