Product details
Overview
AM3517AZCNC from Texas Instruments is a 600-MHz ARM Cortex-A8 microprocessor with PowerVR SGX graphics acceleration, 256KB L2 cache, DDR2/mDDR memory controller, and integrated display subsystem supporting NTSC/PAL video output - deployed in industrial HMIs, digital signage, and portable media players.
For engineers reviewing the AM3517AZCNC datasheet, AM3517AZCNC pinout, AM3517AZCNC application, or AM3517AZCNC equivalent, key selection criteria include its 491-pin NFBGA (ZCN) package, dual DACs for analog video, 186 GPIOs, USB OTG + multiport host support, and Linux/Android OS compatibility.
Technical Context
The AM3517AZCNC integrates an ARMv7-compliant Cortex-A8 core with NEON SIMD and VFP coprocessors, delivering >2× ARMv6 SIMD performance. 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/SRAM interfacing.
Graphics and display are handled by a dedicated PowerVR SGX accelerator (AM3517-only), paired with a programmable display subsystem featuring triple-layer composition, temporal dithering, HD resolution support, and RGB/S-Video/CVBS outputs - all synchronized via a 75-MHz pixel clock and REC656/CCIR656 compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-A8 @ 600 MHz - enables real-time Linux kernel scheduling and deterministic interrupt latency for industrial control tasks. |
| L2 Cache | 256KB unified - reduces external memory bandwidth pressure during multimedia decoding and GUI rendering. |
| Graphics Accelerator | PowerVR SGX (10 MPoly/sec) - hardware-accelerated OpenGL ES 1.1/2.0 and OpenVG 1.0 for smooth UI transitions and 3D overlays. |
| Memory Interface | 166-MHz DDR2/mDDR controller with 1GB address space - supports low-power mobile SDRAM for battery-operated devices. |
| Display Outputs | Dual parallel digital (24-bit RGB) + composite NTSC/PAL + S-Video - enables simultaneous main display and auxiliary video feed without external encoders. |
| Video DACs | Two 10-bit DACs - generate analog CVBS and S-Video signals directly from internal frame buffers, eliminating discrete video DAC ICs. |
| USB Support | OTG + 3-port high-speed host - allows device-mode peripheral attachment (e.g., USB storage) and simultaneous host control of HID, mass storage, and audio class devices. |
Pinout & Package
AM3517AZCNC uses a 491-ball NFBGA package (17.1 mm × 17.1 mm, 0.65-mm pitch) with Via Channel™ array technology. Ball assignment follows ZCN suffix designation per TI SPRS550F Rev F.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_CORE | Core power supply | 1.2V nominal - requires tight regulation and local decoupling to sustain 600-MHz CPU operation without voltage droop. |
| VDDS_SRAM_MPU | MPU SRAM power rail | 1.2V - powers on-chip 64KB RAM; independent from VDD_CORE for optimized power domain sequencing. |
| SDRC_D0–D31 | DDR2 data bus | 32-bit bidirectional interface - supports burst transfers at 166 MHz; requires matched trace lengths and SSTL_18 termination. |
| DSS_DATA0–DSS_DATA23 | Parallel RGB/YUV display data | 24-bit digital video bus - drives LCD panels directly; supports programmable polarity, timing, and data alignment per display standard. |
| USB0_DP / USB0_DM | USB 2.0 differential pair | Full-speed/low-speed OTG PHY interface - integrated transceiver eliminates need for external USB PHY IC. |
| TV_OUT1 / TV_OUT2 | Analog video outputs | Composite CVBS and S-Video Y/C signals - sourced from internal 10-bit DACs; require passive RC filtering per TI layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| ARM NEON + VFP Coprocessor | Hardware-accelerated integer/floating-point SIMD operations - enables real-time audio processing, image filtering, and codec execution without CPU load saturation. |
| Triple-Layer Display Processor | Independent scaling, rotation (90°/180°/270°), and alpha blending across three layers - supports overlay-based UIs with transparent widgets and video-in-picture. |
| VPFE 16-bit Video Input Port | 75-MHz pixel clock capture interface - acquires HD video from CMOS sensors with RAW, REC656, or YCbCr422 formats and built-in black-level compensation. |
| System DMA (sDMA) | 32-channel configurable priority controller - offloads CPU from memory-to-peripheral transfers (e.g., McBSP audio streaming, SDIO DMA), reducing ISR overhead. |
| HECC CAN Controller | High-End CAN with message objects and FIFO - meets ISO 11898-1 for robust industrial fieldbus communication with error confinement and timestamping. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3505AZCND | No PowerVR SGX graphics accelerator; identical CPU, memory, and peripheral set otherwise. | Suitable for non-graphics-intensive applications like headless gateways or basic HMIs without 3D/UI acceleration. | Select AM3505AZCND when graphics acceleration is unnecessary and BOM cost reduction is prioritized over visual performance. |
| AM3358BZCZ100 | Newer 300-MHz ARM Cortex-A8; adds PRU-ICSS for real-time I/O, but lacks dual DACs and TV-out capability. | Better suited for industrial protocol gateways (Modbus, EtherCAT) requiring deterministic I/O, not analog video output. | Choose AM3358BZCZ100 for real-time control extensions and longer-term availability, accepting trade-offs in analog video functionality. |
Compared with AM3505AZCND and AM3358BZCZ100, the AM3517AZCNC uniquely combines TV-out DACs, PowerVR SGX graphics, and 600-MHz performance - making it optimal for cost-sensitive embedded displays where analog video and UI richness are mandatory.

FAQ
What operating systems are officially supported on the AM3517AZCNC?
The AM3517AZCNC is validated for Linux® (including TI's Processor SDK Linux), Windows® CE, and Android™. TI provides board support packages, kernel drivers, and graphics libraries (PVRSDK) enabling full utilization of the PowerVR SGX accelerator and display subsystem in AM3517AZCNC-based designs.
Does the AM3517AZCNC support DDR3 memory?
No, the AM3517AZCNC supports only DDR2 and mobile DDR (mDDR) SDRAM via its SDRC controller. It does not support DDR3 signaling or command protocols. Designs requiring DDR3 must migrate to newer Sitara processors such as the AM437x or AM57x series.
What is the thermal design power (TDP) of the AM3517AZCNC under typical operation?
At 600 MHz and 1.2V core voltage, the AM3517AZCNC exhibits a typical power consumption of 650 mW in active mode with moderate peripheral usage. Thermal design must accommodate θJA = 25.2°C/W (ZCN package) and include ≥4 thermal vias under the die pad per TI layout recommendations in SPRS550F.
Can the AM3517AZCNC's USB OTG port operate as a device-only interface?
Yes, the AM3517AZCNC USB0 port supports full OTG functionality including device mode, enabled via ID pin detection and software configuration. In device mode, it enumerates as a USB 2.0 full-speed device (e.g., CDC ACM, MSC) without requiring external PHY or level-shifting components.
How many independent display interfaces does the AM3517AZCNC support simultaneously?
The AM3517AZCNC supports two concurrent display outputs: one parallel digital (24-bit RGB) and one analog (CVBS or S-Video). Both are driven from the same display subsystem with independent timing generators, enabling mirrored or extended desktop configurations in AM3517AZCNC-based systems.
