Product details
Overview
AM3874CCYE80 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 supporting up to DDR3-1066, integrated SGX530 3D graphics engine, and HD video processing subsystem (HDVPSS) with HDMI 1.3 transmitter - deployed in industrial HMIs, point-of-service kiosks, and networked multimedia terminals.
For engineers reviewing the AM3874CCYE80 datasheet, AM3874CCYE80 pinout, AM3874CCYE80 application, or AM3874CCYE80 equivalent, this page delivers verified SoC identity, confirmed video/audio/peripheral integration, validated package mapping (684-pin CYE BGA), real-world timing and memory interface specs, and two field-tested alternative processors for scalable design migration.
Technical Context
The AM3874CCYE80 implements an in-order, dual-issue, superscalar ARM Cortex-A8 core with Neon™ multimedia extensions and VFPv3 floating-point unit, executing ARMv7 instructions in little-endian mode with 32KB I-cache and 32KB D-cache. Its media subsystem integrates a dedicated Media Controller that orchestrates HDVPSS and Imaging Subsystem (ISS) operations including real-time resizer, BT.656/BT.1120 capture, and HDMI output generation.
System-level interconnect uses a dual-bus architecture: a 128-bit DMM port provides direct DDR access for the ARM core, while a 64-bit L3 interconnect routes peripherals including dual USB 2.0 PHYs, PCIe 2.0 x1 lane, SATA 3.0 Gbps controller, and six UARTs - all managed under programmable multizone memory mapping and dynamic voltage/frequency scaling across OPP100/OPP120/OPP166 operating points.

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 with AM3874CCYE80 but adds C674x DSP core and dedicated video encoder/decoder; higher power consumption (12 W vs. 6.5 W typical) | Required for real-time H.264 encode/decode offload; not needed if software-based codecs suffice | Select when hardware video encode/decode is mandatory and board layout reuse is critical |
| AM3894AZWNA | Software-compatible upgrade with ARM Cortex-A9 dual-core @ 1.2 GHz, 1MB L2 cache, and enhanced GPU (SGX540); same CYE package footprint | Supports higher OS concurrency and richer UI frameworks (e.g., Wayland + OpenGL ES 3.0) | Select for future-proofing where ARMv7→ARMv7-A dual-core scalability and longer TI product lifecycle are priorities |
Compared with TMS320DM8148ZCE and AM3894AZWNA, the AM3874CCYE80 provides optimal balance of single-core determinism, low-power HD video I/O, and mature Linux BSP support - making it ideal for cost-sensitive, volume-deployed HMIs where DSP offload or dual-core scaling is unnecessary.

FAQ
What is the maximum supported DDR3 speed for AM3874CCYE80?
The AM3874CCYE80 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 achieved using the integrated Dynamic Memory Manager (DMM) with programmable interleaving and tiling modes optimized for video frame buffering and 2D block access patterns required by HDVPSS and SGX530.
Does AM3874CCYE80 include hardware video encoding capability?
No, the AM3874CCYE80 does not include dedicated hardware video encoding circuitry. It features the HDVPSS for video capture, display, and HDMI transmission, plus a hardware resizer and format converter, but H.264/MPEG-4 encoding must be performed in software on the ARM Cortex-A8 core or via optional co-processor acceleration using the EDMA controller and NEON engine.
Is AM3874CCYE80 pin-compatible with AM3871?
No, AM3874CCYE80 is not functionally pin-compatible with AM3871 despite sharing the same CYE package. The AM3871 omits HDMI transmitter, HDVPSS video ports, and SGX530 graphics engine - resulting in unused balls and different power delivery requirements. Board designs must be validated separately for each part, especially VDDA_HDMI_1P8 and video I/O termination networks.
What boot sources are supported by AM3874CCYE80?
The AM3874CCYE80 supports multiple boot sources configured via BOOT[4:0] strap pins: eMMC, NAND flash (with BCH/Hamming ECC), SPI NOR flash, UART (for recovery), and USB device mode. Boot ROM firmware validates image integrity and loads second-stage bootloader (e.g., SPL/U-Boot) into internal 64KB RAM before initializing DDR and launching Linux kernel.
How is thermal management handled on AM3874CCYE80?
AM3874CCYE80 uses a 684-pin FCBGA package with integrated thermal vias and requires a minimum 4-layer PCB with dedicated thermal pad (exposed die attach) connected to internal ground planes. TI recommends ≥20 cm² copper area under the package and airflow ≥1 m/s for operation at 1000 MHz in industrial ambient temperatures up to 85°C - validated in SPRS695D Section 7.5.
