Product details
Overview
AM3505AZERQ5 from Texas Instruments is a 600-MHz ARM Cortex-A8 microprocessor with integrated display subsystem, dual 10-bit DACs for NTSC/PAL video output, USB OTG/Host, EMAC, CAN, and 186 GPIOs - designed for industrial HMIs, digital signage, and portable media players requiring Linux or Android OS support.
For engineers reviewing the AM3505AZERQ5 datasheet, AM3505AZERQ5 pinout, AM3505AZERQ5 application, or AM3505AZERQ5 equivalent, key selection criteria include its 484-pin PBGA (ZER) package, absence of PowerVR SGX graphics (vs. AM3517), TV-out capability, DDR2/mDDR memory interface, and dual-CAN controller support in industrial automation contexts.
Technical Context
The AM3505AZERQ5 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 a 166-MHz SDRC controller supporting up to 1GB DDR2/mDDR and a 16-bit GPMC for NAND/NOR/SRAM interfacing.
It integrates a programmable display subsystem supporting dual LCD panels, RFBI, RGB up to 24-bit, and composite/S-video output via two 10-bit DACs. The device lacks the PowerVR SGX graphics accelerator found in AM3517, distinguishing its multimedia capability profile.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3517AZERQ5 | Includes PowerVR SGX graphics accelerator; identical pinout and package | Required for OpenGL ES 1.1/2.0 rendering in gaming or advanced GUIs | Select when 3D graphics acceleration is mandatory; otherwise AM3505AZERQ5 offers lower cost and power |
| AM3352BZCZ100 | ARM Cortex-A8 at 1 GHz; PRU-ICSS for real-time I/O; no integrated video DACs | Suited for industrial networking gateways needing EtherCAT or PROFIBUS, not video output | Choose for higher CPU throughput and deterministic peripheral control; add external DAC if video needed |
Compared with AM3517AZERQ5, AM3505AZERQ5 omits PowerVR SGX but retains identical video DACs and display pipeline - making it optimal for cost-sensitive video-centric designs. Versus AM3352BZCZ100, it trades PRU flexibility and clock speed for built-in analog video output and simpler software stack integration.

FAQ
What is the maximum DDR2 memory speed supported by the AM3505AZERQ5?
The AM3505AZERQ5 supports DDR2/mDDR memory interfaces operating at up to 166 MHz, enabling a theoretical peak bandwidth of 2.66 GB/s with a 16-bit bus. This speed is validated under recommended operating conditions (VDD_DDR = 1.8 V, ambient temperature ≤ 85°C) and requires proper PCB layout with matched trace lengths and termination.
Does the AM3505AZERQ5 include a graphics accelerator like the PowerVR SGX?
No, the AM3505AZERQ5 does not include the PowerVR SGX graphics accelerator. That feature is exclusive to the AM3517 variant. The AM3505AZERQ5 relies on its ARM Cortex-A8 core with NEON SIMD extensions for 2D graphics composition and video processing, supported by its dedicated display subsystem with scaling and color conversion.
Can the AM3505AZERQ5 generate both NTSC and PAL video outputs simultaneously?
Yes, the AM3505AZERQ5 integrates two independent 10-bit DACs that support concurrent NTSC and PAL composite video generation, or S-video output. The display subsystem routes pixel data to either DAC independently, allowing dual-monitor configurations - for example, NTSC to a legacy CRT and PAL to an LCD panel - using shared timing resources.
What is the function of the ZER package suffix in AM3505AZERQ5?
The ZER suffix in AM3505AZERQ5 denotes the 484-pin Plastic Ball Grid Array package with 23.2 mm × 23.2 mm body size and 1-mm ball pitch. It distinguishes this variant from the 491-pin NFBGA (ZCN) package and confirms compatibility with standard PBGA assembly processes and thermal profiles defined in TI's SPRS550F datasheet.
How many CAN interfaces does the AM3505AZERQ5 support, and what protocol versions are implemented?
The AM3505AZERQ5 supports one High-End CAN (HECC) controller compliant with ISO 11898-1, capable of bit rates up to 1 Mbps. It implements full CAN 2.0B functionality including identifier masking, message objects, and transmit/receive FIFOs - suitable for industrial automation networks but not CAN FD.
