Product details
Overview
AM3505AZCN from Texas Instruments is a 600-MHz ARM Cortex-A8 microprocessor with integrated display subsystem, dual 10-bit DACs for NTSC/PAL video output, 491-pin NFBGA (17.1 × 17.1 mm, 0.65-mm pitch), and support for DDR2/mDDR memory interfaces up to 1 GB. It targets industrial HMI, digital signage, and portable media players requiring embedded Linux or Android OS execution.
For engineers reviewing the AM3505AZCN datasheet, AM3505AZCN pinout, AM3505AZCN application, or AM3505AZCN equivalent, key selection criteria include its lack of PowerVR SGX graphics (vs. AM3517), TV-out capability in ZCN package, 186 GPIOs, 4 UARTs with IrDA/CIR, and 12 general-purpose timers - all critical for real-time industrial control and multimedia interface design.
Technical Context
The AM3505AZCN implements an in-order, dual-issue, superscalar ARMv7 architecture with NEON SIMD and VFP coprocessors, 16KB/16KB L1 cache, and 256KB L2 cache. Its memory subsystem includes SDRC controller for DDR2/mDDR at 166 MHz and GPMC supporting NAND/NOR flash, SRAM, and FPGA glueless interfacing.
It integrates a programmable display subsystem with RGB/S-Video/NTSC/PAL outputs, temporal dithering, image rotation (90°/180°/270°), and resize (1/4× to 8×), alongside VPFE 16-bit video input port supporting REC656/YCbCr422 formats at up to 75 MHz pixel clock - all without PowerVR SGX hardware acceleration.
Key Specifications

Pinout & Package
AM3505AZCN uses a 491-ball NFBGA (ZCN suffix) with 0.65-mm pitch and 17.1 × 17.1 mm body size. Ball assignments are defined across four quadrants (A–D) per TI SPRS550F Figures 4-1 to 4-4, with dedicated power domains (VDD_CORE, VDDSHV, VDDS_SRAM, VDDA_DAC), high-speed interfaces (SDRC, GPMC, DSS), and configurable peripherals (UART, McSPI, McBSP, I²C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DSS_ACBIAS | Analog bias for DAC output | Required 2.5-V reference for stable NTSC/PAL video amplitude; must be decoupled per TI layout guidelines |
| DSS_PCLK | Pixel clock output | Programmable 75-MHz max clock driving LCD panel timing; synchronous with DSS_DATA[0:23] bus |
| SDRC_D[0:31] | DDR2/mDDR data bus | 32-bit bidirectional data path with DQS strobes and DM masking - supports burst transfers for display frame buffers |
| GPMC_A[0:14], _NCS[0:7] | General-purpose memory address/chip-select | Glueless interface to NOR/NAND flash, SRAM, or FPGA; 128 MB per chip-select, asynchronous protocol control |
| UART1_TX/RX/CTS/RTS | Primary UART signals | Full-handshake RS-232/RS-485 interface; IrDA/CIR mode supported on UART1 only |
Key Features
| Feature | Design Value |
|---|---|
| Display Subsystem | Supports dual LCD panels, NTSC/PAL composite, S-Video, and RFBI - enables multi-display industrial HMIs without external TCON |
| Video Processing Front End (VPFE) | 16-bit parallel input with REC656/YCbCr422 support and optical black clamping - simplifies camera module integration |
| System DMA Controller | 32-channel sDMA with configurable priority - offloads CPU for high-throughput video capture and display refresh |
| Power Management | Comprehensive PRCM with dynamic voltage/frequency scaling and multiple low-power states - extends battery life in portable media players |
| Peripheral Integration | 4 UARTs, 3 I²C controllers, 5 McBSP ports (2 with sidetone), 4 McSPI, HDQ/1-Wire - reduces BOM count for sensor-rich industrial gateways |

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 |
|---|---|---|---|
| AM3517AZCN | Includes PowerVR SGX graphics accelerator; identical pinout and package | Required for OpenGL ES 1.1/2.0-accelerated UI rendering and gaming effects | Select AM3517AZCN when 3D graphics acceleration is mandatory; AM3505AZCN suffices for 2D-only displays |
| AM3352BZCZ | ARM Cortex-A8 @ 1 GHz, PRU-ICSS for real-time I/O, no analog video DACs, 324-pin BGA | Targeted at industrial automation with deterministic I/O; lacks native NTSC/PAL output | Choose AM3352BZCZ for PRU-based motor control or EtherCAT; retain AM3505AZCN for legacy analog video compatibility |
Compared with AM3517AZCN, AM3505AZCN removes PowerVR SGX but retains full display subsystem and DACs - reducing cost and power for 2D-centric applications. Versus AM3352BZCZ, it offers superior analog video integration but lacks PRU real-time co-processors and higher clock speed.

FAQ
What is the maximum DDR2 memory capacity supported by the AM3505AZCN?
The AM3505AZCN supports up to 1 GB of total addressable space via its SDRC memory controller, configured for 16- or 32-bit-wide DDR2 or mDDR SDRAM operating at 166 MHz. This capacity is sufficient for dual-frame buffers in 720p display applications and is validated per TI SPRS550F Section 6.4.
Does the AM3505AZCN include PowerVR SGX graphics acceleration?
No, the AM3505AZCN does not include PowerVR SGX graphics acceleration. That feature is exclusive to the AM3517 variant. The AM3505AZCN relies on its programmable display subsystem and CPU-based rendering for 2D graphics, making it suitable for cost-sensitive applications where OpenGL ES acceleration is unnecessary.
What video output standards does the AM3505AZCN support natively?
The AM3505AZCN natively supports composite NTSC and PAL video output, as well as S-Video (Y/C), through its two integrated 10-bit DACs. These outputs are enabled in the ZCN package variant and require proper AC-biasing via the DSS_ACBIAS pin per TI SPRS550F Section 5.10.
How many general-purpose timers are available on the AM3505AZCN?
The AM3505AZCN includes twelve 32-bit general-purpose timers, plus one 32-bit watchdog timer and one 32-kHz sync timer. These timers support PWM generation, time-stamping, and periodic interrupt servicing - critical for motor control, sensor sampling, and real-time task scheduling in industrial applications.
Is the AM3505AZCN pin-compatible with the AM3517AZCN?
Yes, the AM3505AZCN and AM3517AZCN share identical 491-pin NFBGA (ZCN) packaging, pin assignments, and electrical characteristics. They differ only in internal IP - AM3517AZCN includes PowerVR SGX, while AM3505AZCN omits it - enabling hardware-compatible migration paths within the same PCB layout.
