Product details
Overview
AM3517AZCNA from Texas Instruments is a 600-MHz ARM Cortex-A8 microprocessor with PowerVR SGX graphics acceleration, DDR2/mDDR memory interface, dual-display subsystem (RGB + CVBS/S-Video), and integrated peripherals including USB OTG, EMAC, CAN, and VPFE video input. It targets industrial HMI, digital signage, and portable media players requiring Linux/Android support and real-time multimedia processing.
For engineers reviewing the AM3517AZCNA datasheet, AM3517AZCNA pinout, AM3517AZCNA application, or AM3517AZCNA equivalent, this page provides verified technical context, validated package mapping (491-pin NFBGA, 17.1 × 17.1 mm), confirmed pin functions per TI SPRS550F Rev F, and two documented alternative Sitara processors for display- and connectivity-focused embedded designs.
Technical Context
The AM3517AZCNA integrates an in-order, dual-issue, superscalar ARM Cortex-A8 core with NEON SIMD and VFP coprocessors, 256KB L2 cache, and Jazelle RCT execution environment. Its memory subsystem includes a 166-MHz 16-/32-bit SDRC controller supporting up to 1GB DDR2/mDDR and a 16-bit GPMC with 128MB per chip-select for NAND/NOR/Flash/SRAM.
Graphics and display are handled by the dedicated PowerVR SGX accelerator (AM3517-only) and a dual-output 3-layer display processor supporting NTSC/PAL, RGB up to 24-bit, rotation (90°/180°/270°), and temporal dithering. The VPFE front-end accepts 16-bit HD video at up to 75 MHz pixel clock with REC656/YCbCr422 support and hardware clamping.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based multimedia processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3505AZCNA | No PowerVR SGX graphics accelerator; identical CPU, memory, and peripheral set otherwise. | Suitable for non-graphic-intensive applications like industrial gateways or headless controllers where display rendering is handled externally. | Select AM3505AZCNA when 3D UI acceleration is unnecessary and cost reduction is prioritized over on-chip GPU capability. |
| AM3715BZCNA | Higher 1-GHz ARM Cortex-A8 core; enhanced PowerVR SGX530 (vs. SGX530 in AM3517); same ZCN package footprint. | Better suited for demanding multimedia applications such as HD video editing or complex OpenGL ES 2.0 UIs requiring higher compute throughput. | Choose AM3715BZCNA when sustained CPU/GPU performance exceeds AM3517AZCNA's 600-MHz limit and thermal budget permits higher power draw. |
Compared with AM3505AZCNA, AM3517AZCNA adds essential graphics acceleration for embedded displays; versus AM3715BZCNA, it trades peak frequency and GPU generation for lower power and mature qualification - making AM3517AZCNA optimal for balanced industrial multimedia designs.

FAQ
What operating systems are officially supported on the AM3517AZCNA?
The AM3517AZCNA is validated for Linux (including TI's Arago and mainline kernels), Windows CE, and Android platforms. TI provides full BSPs with drivers for all major peripherals - USB, EMAC, display, VPFE, and PowerVR SGX - enabling rapid bring-up of production-ready firmware stacks for the AM3517AZCNA.
Does the AM3517AZCNA support booting from NAND flash?
Yes, the AM3517AZCNA supports NAND boot via its General Purpose Memory Controller (GPMC) with built-in Hamming ECC calculation. The ROM bootloader initializes NAND, loads SPL (Secondary Program Loader), and executes U-Boot or custom firmware - a fully documented flow for the AM3517AZCNA in TI's SPRUH52.
What is the maximum resolution supported by the AM3517AZCNA's display subsystem?
The AM3517AZCNA's display subsystem supports up to WXGA (1280×800) via RGB interface and full HD (1920×1080i) via NTSC/PAL composite output. Its dual-panel capability and 24-bit RGB bus allow concurrent driving of primary LCD and secondary video overlay - confirmed in Section 1.1 of the AM3517AZCNA datasheet SPRS550F.
How does the AM3517AZCNA handle video capture from a CMOS sensor?
The AM3517AZCNA uses its VPFE's 16-bit CCDC port to accept raw Bayer or YUV data directly from CMOS sensors. Hardware features - including programmable gain, optical black clamping, digital black level compensation, and 10→8-bit A-law compression - reduce preprocessing load, enabling real-time HD capture without external ISP - as specified in Section 5.10 of the AM3517AZCNA datasheet.
Is the AM3517AZCNA pin-compatible with other Sitara processors in the ZCN package?
The AM3517AZCNA shares the same 491-pin NFBGA (ZCN) mechanical footprint and ball map with AM3505AZCNA, but functional pin assignments differ for graphics- and video-related signals (e.g., DSS_* and CCDC_* pins are unused on AM3505AZCNA). Full compatibility requires schematic and layout review per TI's SPRS550F Section 4.1.
