Texas Instruments XAM3517ZCN

Overview

XAM3517ZCN 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 XAM3517ZCN datasheet, XAM3517ZCN pinout, XAM3517ZCN application, or XAM3517ZCN equivalent, key selection criteria include its 491-pin NFBGA (ZCN) package, TV-out capability (distinguishing it from ZER variants), 1.2V core voltage, 166-MHz DDR2 interface, and Linux/Android OS support.

Technical Context

The XAM3517ZCN integrates an in-order, dual-issue, superscalar ARM Cortex-A8 core with NEON SIMD and VFP coprocessors, Jazelle RCT execution environment, and embedded trace macrocell (ETM) for noninvasive debug. Its memory architecture includes 16KB instruction and 16KB data L1 caches plus 256KB unified L2 cache with ECC support.

System-level interconnect uses hierarchical L3/L4 networks enabling concurrent high-bandwidth access to DDR2/mDDR via SDRC, GPMC for NAND/NOR/SRAM, and multiple peripheral domains including VPFE video input, DSS display processor with RGB/S-Video/CVBS outputs, and HECC CAN controller.

FAQ

What distinguishes XAM3517ZCN from AM3505ZCN?

XAM3517ZCN includes the PowerVR SGX graphics accelerator and full TV-out capability (CVBS/S-Video), while AM3505ZCN omits both. The XAM3517ZCN also enables VPFE video capture and dual-display composition - critical for digital signage and media player use cases where AM3505ZCN would require external video ICs.

Does XAM3517ZCN support Linux and Android operating systems?

Yes, XAM3517ZCN is fully supported by TI's Linux SDK (including mainline kernel drivers) and Android BSPs. Its ARM Cortex-A8 core, NEON coprocessor, and memory subsystem meet the minimum requirements for Android 4.x and later, with verified boot, graphics, and display stack integration.

What is the function of the ZCN suffix in XAM3517ZCN?

The ZCN suffix denotes the 491-pin NFBGA package (17.10 mm × 17.10 mm, 0.65-mm pitch) with Via Channel™ array technology. This package variant supports TV-out functionality and differs from the ZER (484-pin PBGA) variant, which lacks TV-out pins and uses a larger 1-mm pitch footprint.

Can XAM3517ZCN interface directly with DDR2 SDRAM?

Yes, XAM3517ZCN integrates a dedicated SDRC (Synchronous DRAM Controller) supporting 16-/32-bit DDR2 and mDDR at up to 166 MHz. It provides all necessary control, address, data, and DQS signals - requiring only compliant DDR2 chips and proper PCB layout per TI's DDR2 design guide.

What video standards does XAM3517ZCN support for analog output?

XAM3517ZCN supports NTSC and PAL composite video (CVBS) output via dedicated TV_OUT1/TV_OUT2 pins, and S-Video output using separate luma/chroma signals. These outputs comply with ITU-R BT.601 and EIA-770.1 standards and require no external encoder - confirmed in Section 1.1 and Figure 1-1 of SPRS550F.
