Overview
AM3352ZCZD72 from Texas Instruments is a 600-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 (RGMII/MII), and PRU-ICSS supporting EtherCAT and PROFINET - deployed in industrial HMIs and programmable logic controllers.
For engineers reviewing the AM3352ZCZD72 datasheet, AM3352ZCZD72 pinout, AM3352ZCZD72 application, or AM3352ZCZD72 equivalent, this page delivers verified specifications, package mapping, validated alternatives, and real-world use context for embedded industrial SoC selection.
Technical Context
The AM3352ZCZD72 implements a dual-core programmable real-time unit subsystem (PRU-ICSS) with two 200-MHz RISC engines, 12KB shared RAM (parity), and dedicated MII/Ethernet PHY interfaces - enabling deterministic industrial protocol offload independent of the Cortex-A8 core. It integrates PowerVR SGX530 graphics acceleration and IEEE 1588v1 PTP support for time-synchronized motion control.
Its memory subsystem includes a 16-bit DDR2/DDR3/DDR3L interface (up to 400-MHz clock), GPMC with NAND/NOR/SRAM support and BCH 4-/8-/16-bit ECC, and 64KB OCMC RAM with retention mode for fast wakeup - all managed via a centralized PRCM module with SmartReflex Class 2B AVS and DVFS.

FAQ
What is the maximum operating frequency of the AM3352ZCZD72?
The AM3352ZCZD72 operates at a guaranteed maximum frequency of 600 MHz across its –40°C to +105°C industrial temperature range. This frequency is silicon-revision dependent and confirmed in TI's SPRS717L datasheet Table 3-1 and Section 5.4 (Operating Performance Points). The AM3352ZCZD72 does not support 800-MHz or 1-GHz OPPs like higher-tier variants such as AM3358 or AM3359.
Does the AM3352ZCZD72 include PRU-ICSS hardware, and what protocols does it support?
Yes, the AM3352ZCZD72 includes a full PRU-ICSS subsystem with two 200-MHz programmable real-time units, 12KB shared RAM, and dedicated MII/Ethernet interfaces. It supports EtherCAT, PROFINET, EtherNet/IP, and CANopen via TI's PRU-ICSS firmware libraries - though ZCZ-package pinout limits some PRU I/O compared to ZCE variants.
What memory interfaces are supported by the AM3352ZCZD72?
The AM3352ZCZD72 supports a 16-bit DDR2/DDR3/DDR3L interface (up to 400-MHz clock, 800-Mbps data rate), GPMC for NAND/NOR/SRAM (with BCH 4-/8-/16-bit ECC), and 64KB OCMC RAM. It does not support LPDDR2 or LPDDR3 - those are limited to AM3359/AM3358 variants per TI's device comparison table.
Is the AM3352ZCZD72 pin-compatible with other AM335x ZCZ packages?
Yes, the AM3352ZCZD72 shares identical 324-ball NFBGA (ZCZ) mechanical footprint and pinout with AM3354ZCZ, AM3356ZCZ, AM3357ZCZ, AM3358ZCZ, and AM3359ZCZ. All ZCZ variants use the same ball map, allowing drop-in replacement within thermal and power envelope constraints - verified in TI SPRS717L Section 9.2.
What graphics capabilities does the AM3352ZCZD72 provide?
The AM3352ZCZD72 integrates the PowerVR SGX530 3D graphics engine, delivering up to 20 million polygons per second and supporting OpenGL ES 1.1/2.0, OpenVG 1.1, and Direct3D Mobile APIs. Its LCD controller supports 24-bit RGB output at resolutions up to 2048×2048 with a 126-MHz pixel clock - confirmed in SPRS717L Section 1.1 and Figure 1-1.
