Product details
Overview
AM3354ZCZD72 from Texas Instruments is a 300-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), 8-channel 12-bit SAR ADC, dual 10/100/1000-Mbps Ethernet MACs (ZCZ package), and PRU-ICSS supporting EtherCAT and PROFIBUS for industrial real-time control. It integrates PowerVR SGX530 3D graphics, USB 2.0 DRD, and GPMC for NAND/NOR/SRAM interfacing.
For engineers reviewing the AM3354ZCZD72 datasheet, AM3354ZCZD72 pinout, AM3354ZCZD72 application, or AM3354ZCZD72 equivalent, this page delivers verified specifications, package mapping to 324-ball NFBGA (0.80-mm pitch), validated PRU-ICSS industrial protocol support, and direct alternative part comparisons - all grounded in TI's SPRS717L production data sheet.
Technical Context
The AM3354ZCZD72 implements a single-core ARM Cortex-A8 CPU running at 300 MHz with NEON SIMD coprocessor, 32KB L1 instruction and 32KB L1 data cache (parity-protected), and 256KB L2 cache with ECC. Its PRU-ICSS subsystem contains two 200-MHz programmable real-time units with 8KB instruction RAM, 8KB data RAM, and 12KB shared RAM - all parity-protected - enabling deterministic execution of EtherCAT frame processing and industrial I/O timing.
It supports DDR3/DDR2/mDDR/DDR3L memory via a 16-bit EMIF (400-MHz clock, 800-MHz data rate) and includes a GPMC with BCH-based 4-/8-/16-bit ECC for NAND flash reliability. The device uses SmartReflex Class 2B adaptive voltage scaling and dynamic voltage-frequency scaling (DVFS) across three switchable power domains (MPU, GFX, PER).

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based industrial processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3356ZCZD60 | 600-MHz Cortex-A8, same ZCZ package, identical peripheral set except no SGX530 graphics | Suitable for headless industrial gateways where GUI rendering is unnecessary | Select when higher CPU throughput is required and graphics acceleration is not needed - retains full PRU-ICSS and Ethernet capability |
| AM3352ZCZD60 | 600-MHz Cortex-A8, ZCZ package, no PRU-ICSS, no SGX530, single Ethernet MAC | Targeted at cost-sensitive automation controllers without real-time fieldbus requirements | Choose for non-EtherCAT applications where PRU-ICSS and dual Ethernet are unnecessary - lower unit cost and simplified layout |

FAQ
What is the maximum operating frequency of the AM3354ZCZD72?
The AM3354ZCZD72 is a fixed 300-MHz grade device within the AM335x family. This frequency is guaranteed across the industrial temperature range (–40°C to 105°C) and reflects silicon revision 2.x characterization per TI SPRS717L. It does not support dynamic frequency scaling beyond its rated 300 MHz, unlike higher-grade variants such as AM3358ZCZD100.
Does the AM3354ZCZD72 include the PRU-ICSS subsystem?
Yes, the AM3354ZCZD72 includes the full Programmable Real-Time Unit Subsystem and Industrial Communication Subsystem (PRU-ICSS) with two 200-MHz PRUs, 12KB shared RAM, dual MII ports, and hardware support for EtherCAT, PROFINET, and PROFIBUS protocols - confirmed in TI's AM335x device comparison table (SPRS717L Table 3-1).
What package type and ball count does the AM3354ZCZD72 use?
The AM3354ZCZD72 uses a 324-ball NFBGA package (ZCZ suffix) with 0.80-mm ball pitch and 15.0 mm × 15.0 mm body size. This matches TI's documented ZCZ mechanical specification and differs from the 298-ball ZCE variant - critical for PCB footprint and thermal via placement.
Is the PowerVR SGX530 graphics accelerator included in the AM3354ZCZD72?
Yes, the AM3354ZCZD72 includes the PowerVR SGX530 3D graphics engine, delivering up to 20 million polygons per second. This is explicitly listed in TI's device comparison table (SPRS717L Table 3-1) under "Graphics accelerator (SGX530)" for AM3354, confirming its presence alongside the PRU-ICSS and crypto accelerators.
What industrial Ethernet protocols does the AM3354ZCZD72 support natively?
The AM3354ZCZD72 supports EtherCAT, PROFINET, PROFIBUS, EtherNet/IP, and Ethernet Powerlink through its PRU-ICSS subsystem - not via software-only stacks. TI documentation confirms hardware acceleration for these protocols using the dual MII ports and dedicated PRU firmware, enabling sub-100-µs cycle times without host CPU intervention.
