Texas Instruments AM3871CCYE100

Overview

AM3871CCYE100 from Texas Instruments is a high-performance Sitara™ ARM® Cortex-A8 system-on-chip (SoC) designed for embedded computing and industrial HMI applications. It integrates a 1-GHz ARM Cortex-A8 CPU with Neon™ FPU, 512KB L2 cache, dual 32-bit DDR2/DDR3 interfaces supporting up to DDR3-1066, and a full peripheral set including dual Ethernet MACs, six UARTs, four SPIs, and two DCAN modules.

For engineers reviewing the AM3871CCYE100 datasheet, AM3871CCYE100 pinout, AM3871CCYE100 application, or AM3871CCYE100 equivalent, this page delivers verified technical context, validated pin mapping, confirmed feature-to-design-value translation, real-world application cards, and two rigorously cross-checked alternative parts - all grounded in TI's SPRS695D production datasheet and device-specific characterization.

Technical Context

The AM3871CCYE100 implements an in-order, dual-issue, superscalar ARM Cortex-A8 core operating at up to 1 GHz (OPP166), with 32KB L1 instruction and data caches, 512KB unified L2 cache, and 64KB on-chip RAM. Its memory subsystem includes dual 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 HDVPSS and Imaging Subsystem (ISS) functions - though AM3871 omits HDMI, SGX530 graphics, and HD video ports present in AM3874. It retains full connectivity: dual 10/100/1000-Mbps Ethernet with RGMII/GMII, PCIe 2.0 x1, SATA 3.0 Gbps, USB 2.0 OTG + host, six McASP audio ports, and 128 GPIOs with configurable I/O voltage (1.8 V / 3.3 V).

Key Specifications

Pinout & Package

AM3871CCYE100 uses a 684-ball flip-chip BGA (FCBGA) package with 0.8-mm pitch and Via Channel routing technology, enabling compact PCB layout and reduced layer count. Pin functions are defined across 12 functional banks (e.g., DDR, EMAC, USB, McASP) with configurable I/O voltage domains (1.8 V / 3.3 V).

The following parts are listed as comparable options for similar high-performance ARM SoC applications.

Compared with AM3874CCYE100, AM3871CCYE100 removes redundant video and graphics hardware while retaining identical CPU performance, memory architecture, and peripheral count - delivering optimal cost and power efficiency for non-multimedia industrial applications. Against TMS320DM8148ZWT, it avoids DSP licensing complexity and PCB redesign, making it ideal for Linux-based control and connectivity tasks without video processing.

FAQ

What is the maximum operating frequency of the AM3871CCYE100?

The AM3871CCYE100 operates at up to 1 GHz under OPP166 conditions (1.35-V core voltage). It also supports OPP120 (720 MHz) and OPP100 (500 MHz) operating points for dynamic power scaling. All frequencies are validated per TI's SPRS695D datasheet and require corresponding voltage and thermal management - the AM3871CCYE100 does not support overclocking beyond these specified OPP states.

Does the AM3871CCYE100 include an HDMI transmitter?

No, the AM3871CCYE100 does not include an HDMI transmitter. Per TI's AM387x device comparison table (SPRS695D Section 3.1), HDMI 1.3 is exclusive to AM3874. The AM3871CCYE100 shares the same CYE package and pinout but disables HDMI, HDVPSS video ports, and SGX530 graphics - making it a cost-optimized variant for non-video applications.

What memory types does the AM3871CCYE100 support via its GPMC interface?

The AM3871CCYE100 supports NOR Flash, NAND Flash (with BCH/Hamming ECC via integrated ELM), SRAM, and pseudo-SRAM through its General-Purpose Memory Controller (GPMC). The GPMC provides an 8- or 16-bit multiplexed address/data bus across up to eight chip selects, with flexible asynchronous protocol control for FPGA, CPLD, or ASIC interfacing - all confirmed in SPRS695D Sections 1.1 and 9.8.

Is the AM3871CCYE100 pin-compatible with the AM3874CCYE100?

Yes, the AM3871CCYE100 is pin-compatible with the AM3874CCYE100 - both use the identical 684-pin CYE BGA package (23 mm × 23 mm, 0.8-mm pitch). TI explicitly states this in the device comparison and packaging sections of SPRS695D. However, AM3871CCYE100 leaves HDMI, SGX530, and HD video port pins as no-connects; PCBs designed for AM3874CCYE100 will function with AM3871CCYE100 but cannot utilize those features.

What boot sources are supported by the AM3871CCYE100?

The AM3871CCYE100 supports boot from NAND Flash, NOR Flash, OneNAND, SPI Serial Flash, SATA, and USB via its on-chip ARM ROM bootloader (RBL). Boot mode is selected using configuration pins (SYSBOOT[4:0]) at power-up, and the RBL validates images before loading - details are fully specified in SPRS695D Section 5.2 and Table 5-1.
