Overview
AM3505AZCNC from Texas Instruments is a 600-MHz ARM Cortex-A8 microprocessor with integrated SDRC memory controller, 4 UARTs (one supporting IrDA/CIR), 3 I²C controllers, 12 general-purpose timers, and 186 GPIO pins. It features dual DACs for NTSC/PAL video output, HDQ/1-Wire interface, and supports Linux®, Windows® CE, and Android™ OS in industrial automation and human-machine interface applications.
For engineers reviewing the AM3505AZCNC datasheet, AM3505AZCNC pinout, AM3505AZCNC application, or AM3505AZCNC equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in TI's SPRS550F datasheet and official mechanical documentation for the ZCN package.
Technical Context
The AM3505AZCNC implements an in-order, dual-issue, superscalar ARMv7 architecture with NEON SIMD and VFP coprocessors, delivering over 2× ARMv6 SIMD performance. Its memory subsystem includes 16KB L1 instruction cache, 16KB L1 data cache, and 256KB unified L2 cache, coupled with a 166-MHz 16-/32-bit mDDR/DDR2 interface supporting up to 1GB addressable space.
It integrates a comprehensive peripheral set including a 10/100-Mbit Ethernet MAC, USB OTG + multiport USB host (HS/FS/LS), five McBSPs (two with sidetone/audio buffer), four McSPI ports, and a programmable display subsystem supporting RGB, RFBI, and composite video - all managed via a hierarchical L3/L4 interconnect network and PRCM clock/power control.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_CORE (multiple balls) | Core power supply | Supplies 1.2-V ARM Cortex-A8 core and L1/L2 caches; requires low-ESR decoupling near each ball group |
| SDRC_D0–SDRC_D31 | DDR2/mDDR data bus | 32-bit bidirectional data path; must be length-matched with SDRC_CLK and DQS signals for timing closure |
| DSS_DATA0–DSS_DATA23 | Parallel RGB/YCbCr video output | 24-bit digital display interface supporting up to 2 LCD panels or RFBI; requires controlled impedance routing |
| USB0_DP / USB0_DM | USB OTG physical layer | Differential pair for HS/FS/LS operation; needs 90-Ω differential impedance and ESD protection per USB spec |
| JTAG_TCK / TMS / TDI / TDO | IEEE-1149.1 boundary scan | Enables non-invasive debug, production test, and firmware recovery; requires pull-up/pull-down per TI's reset state table |
Key Features

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 |
|---|---|---|---|
| AM3517AZCNA | Same ZCN package and pinout, but includes PowerVR SGX graphics accelerator; no TV-out capability in ZER variant | Required for OpenGL ES 1.1/2.0 GPU-accelerated UI rendering; not suitable where analog video output is mandatory | Select AM3517AZCNA only when GPU compute or advanced 3D graphics are needed - AM3505AZCNC remains optimal for cost-sensitive video-output-focused designs |
| AM3358BZCZ100 | ARM Cortex-A8 @ 1 GHz, PRU-ICSS for real-time I/O, DDR3 support, but no integrated DACs or TV-out circuitry | Suitable for industrial PLCs and gateway devices needing deterministic real-time I/O; lacks native analog video generation | Choose AM3358BZCZ100 for higher CPU throughput and PRU-based fieldbus offload; retain AM3505AZCNC when NTSC/PAL output is required without external DAC |
Compared with AM3517AZCNA and AM3358BZCZ100, the AM3505AZCNC uniquely balances 600-MHz Cortex-A8 performance, integrated analog video DACs, and industrial peripheral density - making it the most cost-effective choice for HMI and media-centric embedded systems requiring direct composite/S-video output.

FAQ
What is the maximum operating frequency of the AM3505AZCNC?
The AM3505AZCNC operates at a guaranteed maximum frequency of 600 MHz for its ARM Cortex-A8 core, as specified in TI's SPRS550F datasheet Section 5.3. This frequency is maintained under recommended operating conditions (VDD_CORE = 1.2 V ± 3%, junction temperature ≤ 105°C). The AM3505AZCNC does not support dynamic frequency scaling beyond this rated speed.
Does the AM3505AZCNC include a graphics accelerator?
No, the AM3505AZCNC does not include the PowerVR SGX graphics accelerator. That feature is exclusive to the AM3517 variant, as confirmed in TI's SPRS550F Section 3.1 Device Features Comparison. The AM3505AZCNC relies on CPU-based rendering and its integrated display subsystem for 2D composition, scaling, and rotation.
Which video output interfaces are supported by the AM3505AZCNC?
The AM3505AZCNC supports composite NTSC/PAL video and S-Video outputs via its two integrated 10-bit DACs, as documented in SPRS550F Sections 1.1 and 1.3. It also provides parallel digital RGB (up to 24-bit) and RFBI interfaces. Unlike the AM3517, the AM3505AZCNC does not support HDMI or LVDS output natively.
What package type is used for the AM3505AZCNC?
The AM3505AZCNC uses a 491-ball NFBGA package with 0.65-mm pitch and 17.1 mm × 17.1 mm body size (ZCN suffix), as defined in TI's SPRS550F Section 8 and Device Information table. This package is distinct from the 484-pin PBGA (ZER) variant and requires specific PCB footprint and stencil design per TI's mechanical drawings.
Can the AM3505AZCNC run Linux or Android operating systems?
Yes, the AM3505AZCNC is fully supported by Linux (including mainline kernel and TI's Processor SDK Linux), Windows® CE, and Android™, as stated in SPRS550F Section 1.3. Its ARM Cortex-A8 core, MMU, and peripheral set meet the hardware requirements for these high-level OSes, and TI provides validated BSPs and reference bootloaders for production deployment.
