Product details
Overview
AM3871CCYE80 from Texas Instruments is a high-performance Sitara™ ARM® Cortex-A8 system-on-chip (SoC) designed for embedded applications requiring rich multimedia, industrial connectivity, and real-time control. It integrates a 1-GHz ARM Cortex-A8 core with Neon™ SIMD, 512KB L2 cache, dual DDR2/DDR3 interfaces (up to DDR3-1066), dual 10/100/1000 Ethernet MACs with MDIO, and six UARTs - enabling use in industrial HMIs, portable data terminals, and networked kiosks.
For engineers reviewing the AM3871CCYE80 datasheet, AM3871CCYE80 pinout, AM3871CCYE80 application, or AM3871CCYE80 equivalent, key selection considerations include its 684-pin CYE BGA package, absence of HDMI/HDVPSS/SGX530 (vs. AM3874), OPP100/OPP120/OPP166 voltage scaling, and support for boot from NAND/NOR/SD/MMC with on-chip ROM bootloader.
Technical Context
The AM3871CCYE80 implements an in-order, dual-issue, superscalar ARM Cortex-A8 core compliant with ARMv7 architecture and Thumb-2 instruction set, featuring 32KB L1 instruction and 32KB L1 data caches plus 512KB unified L2 cache. Its memory subsystem includes two independent 32-bit DDR2/DDR3 controllers supporting up to 2GB total address space via Dynamic Memory Manager (DMM) and programmable multizone memory mapping.
Peripheral integration centers on the Media Controller, which orchestrates the Imaging Subsystem (ISS) - including parallel camera interface (up to 16-bit raw/BT.656/BT.1120), resizer, and ISIF - and manages EDMA (64 channels + 8 QDMA), GPMC+ELM for NAND/NOR/SRAM, dual DCAN, four SPIs, three MMC/SD/SDIO, and six McASPs with DIT capability for S/PDIF.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3874CCYE80 | Includes HDMI 1.3 transmitter, HDVPSS (dual HD capture/display), SGX530 3D graphics, and additional video DACs - not present in AM3871CCYE80 | Suitable for multimedia-rich endpoints (digital signage, video conferencing) where AM3871CCYE80 lacks video output capability | Select AM3874CCYE80 only when HDMI/HDVPSS/3D graphics are required; otherwise AM3871CCYE80 offers lower cost and power for non-video-centric designs |
| TMS320DM8148ZCEA | Adds C674x DSP core, dedicated video encoder/decoder (H.264 BP/MP), and enhanced HDVPSS - not in AM3871CCYE80 | Targeted at high-throughput video analytics (e.g., license plate recognition, object tracking) where ARM-only processing is insufficient | Choose TMS320DM8148ZCEA when real-time video encode/decode offload is mandatory; AM3871CCYE80 remains optimal for control + light media tasks |
Compared with AM3874CCYE80 and TMS320DM8148ZCEA, AM3871CCYE80 delivers optimized cost/power for ARM-centric industrial applications without video output or DSP acceleration - making it ideal for HMIs, gateways, and data terminals where those features add unnecessary complexity and BOM cost.

FAQ
Does AM3871CCYE80 support HDMI output?
No, AM3871CCYE80 does not support HDMI output. Per the official AM387x device comparison table (SPRS695D), HDMI 1.3 transmitter functionality is exclusive to the AM3874 variant. The AM3871CCYE80 omits the entire HDVPSS block - including HDMI, SD DACs, and HD video capture/display ports - making it unsuitable for direct video display applications requiring HDMI connectivity.
What boot sources are supported by AM3871CCYE80?
AM3871CCYE80 supports boot from NAND flash, NOR flash, SPI serial flash, SD/MMC cards, and UART via its on-chip ROM bootloader (RBL). Boot mode is selected using the 5-bit BOOT_MODE[4:0] strap inputs sampled at reset. The GPMC+ELM interface provides hardware-assisted BCH ECC for NAND reliability, while the MMC/SDIO controllers support 1-/4-/8-bit modes for flexible storage options.
Is the SGX530 graphics engine included in AM3871CCYE80?
No, the SGX530 3D graphics engine is not included in AM3871CCYE80. The device comparison table in SPRS695D explicitly states "SGX530: YES (1) on AM3874, NONE on AM3871". This omission means AM3871CCYE80 relies solely on CPU-based 2D rendering or external GPU solutions - confirming its positioning as a cost-optimized variant for non-graphics-intensive applications.
What is the maximum DDR3 speed supported by AM3871CCYE80?
AM3871CCYE80 supports DDR3-1066 operation, corresponding to a 533-MHz clock frequency on each of its two independent 32-bit DDR3 interfaces. This is confirmed in Section 1.1 Features ("Supports up to DDR2-800 and DDR3-1066") and Table 3-2 ("DDR2/3 Memory Controller: 2 (32-bit Bus Widths)"). The DMM enables efficient interleaved access across both buses for sustained bandwidth in memory-intensive tasks.
How many Ethernet MACs does AM3871CCYE80 integrate?
AM3871CCYE80 integrates two fully independent 10/100/1000 Mbps Ethernet MACs compliant with IEEE 802.3, each supporting MII, RMII, GMII, and RGMII media-independent interfaces. Both MACs include integrated MDIO modules for PHY management and support IEEE 1588 time-stamping - enabling precise synchronization in industrial Ethernet applications such as motion control and distributed I/O systems.
