Product details
Overview
AM3505AZER from Texas Instruments is a 600-MHz ARM Cortex-A8 microprocessor with integrated DDR2/mDDR memory controller, 186 GPIOs, dual 10-bit DACs, USB OTG/Host, EMAC, CAN, and display subsystem supporting NTSC/PAL video output - used in industrial HMIs and embedded single-board computers.
For engineers reviewing the AM3505AZER datasheet, AM3505AZER pinout, AM3505AZER application, or AM3505AZER equivalent, key selection criteria include its 484-pin PBGA (ZER) package, absence of PowerVR SGX graphics (vs. AM3517), TV-out capability, and support for Linux/Android real-time OS deployment on resource-constrained industrial platforms.
Technical Context
The AM3505AZER implements an in-order, dual-issue, superscalar ARMv7 architecture with NEON SIMD and VFP coprocessors, delivering >2× ARMv6 SIMD performance. Its memory subsystem includes 256KB L2 cache, 64KB on-chip SRAM, and a 166-MHz 16-/32-bit SDRC interface supporting up to 1GB DDR2/mDDR.
It integrates a programmable display subsystem with RGB/S-Video/NTSC/PAL outputs, HDQ/1-Wire interface, five McBSP audio ports (two with sidetone), four McSPI controllers, and a GPMC supporting NOR/NAND/Flash/SRAM with glueless FPGA interfacing - all managed via a hierarchical L3/L4 interconnect and PRCM clock/power control.

| System DMA Controller (32 channels) | Offloads CPU from high-bandwidth transfers (e.g., video capture → DDR → display), improving real-time responsiveness |
| EMAC + USB OTG + CAN | Provides triple connectivity options for industrial networking - Ethernet for backbone, USB for local peripherals, CAN for fieldbus devices |
Applications
| Industrial HMI | Embedded SBC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3517AZER | Includes PowerVR SGX graphics accelerator; identical ZER package and pinout | Required for OpenGL ES 1.1/2.0-accelerated UI rendering and gaming effects | Select AM3517AZER only if 3D graphics acceleration is needed - otherwise AM3505AZER offers lower power and cost |
| AM3352BZCZ | ARM Cortex-A8 @ 1 GHz, PRU-ICSS, no analog video DACs, 324-pin BGA | Targets higher-performance industrial PLCs with real-time I/O via PRUs, but lacks native NTSC/PAL output | Choose AM3352BZCZ for deterministic real-time control; retain AM3505AZER when analog video output and proven Linux BSP maturity are priorities |
Compared with AM3517AZER, AM3505AZER omits PowerVR SGX to reduce thermal load and cost while retaining full video DAC and display subsystem functionality; versus AM3352BZCZ, it trades PRU flexibility and higher clock speed for mature analog video support and simpler power delivery.

FAQ
What distinguishes AM3505AZER from AM3517AZER?
The AM3505AZER excludes the PowerVR SGX graphics accelerator present in the AM3517AZER, resulting in lower power consumption and cost while retaining identical packaging (484-pin ZER), pinout, and full display subsystem functionality including dual 10-bit DACs and NTSC/PAL output. Both share the same 600-MHz ARM Cortex-A8 core and peripheral set.
Does AM3505AZER support high-definition video output?
The AM3505AZER supports HD resolution display through its display subsystem, which handles up to 24-bit RGB output and includes hardware image resizing (1/4x to 8x), rotation (90/180/270°), and color space conversion. It does not support HDMI or DisplayPort natively but can drive HD LCD panels directly via parallel interface.
What operating systems are validated for AM3505AZER?
AM3505AZER is officially supported with Linux (including TI's Arago and mainline kernels), Windows CE, and Android. TI provides Board Support Packages (BSPs), bootloader (X-Loader/U-Boot), and graphics drivers optimized for the AM3505AZER's display and memory subsystems.
Can AM3505AZER interface directly with DDR2 SDRAM?
Yes, AM3505AZER integrates a dedicated SDRC (Synchronous DRAM Controller) supporting 16-/32-bit DDR2 and mDDR at 166 MHz, with configurable timing, on-die termination (ODT), and 1 GB total addressable space - enabling direct connection to standard DDR2 components without external memory controller logic.
Is the AM3505AZER pin-compatible with other Sitara processors?
The AM3505AZER shares the same 484-pin ZER package footprint and pinout with the AM3517AZER, allowing mechanical and layout compatibility. However, it is not pin-compatible with later Sitara devices like AM335x or AM437x due to differing peripheral mappings, power domains, and ball assignments.
