Texas Instruments AM3358BZCZ100

Overview

AM3358BZCZ100 from Texas Instruments is a 1-GHz ARM Cortex-A8-based Sitara™ processor with integrated PowerVR SGX530 3D graphics engine, dual 1-Gbps Ethernet MACs with switch and IEEE 1588v1 support, PRU-ICSS for real-time industrial protocols (EtherCAT, PROFINET), and 8-channel 12-bit SAR ADC - deployed in industrial HMIs, programmable logic controllers, and connected medical devices.

For engineers reviewing the AM3358BZCZ100 datasheet, AM3358BZCZ100 pinout, AM3358BZCZ100 application, or AM3358BZCZ100 equivalent, key selection criteria include its 324-ball NFBGA (ZCZ) package, 1000-MHz CPU frequency, DDR3/DDR3L memory interface, PRU-ICSS real-time subsystem, and industrial temperature range (–40°C to 105°C).

Technical Context

The AM3358BZCZ100 implements a dual-core programmable real-time unit subsystem (PRU-ICSS) with two 200-MHz RISC processors, 12KB shared RAM, and dedicated MII/Ethernet ports enabling deterministic EtherCAT and PROFINET execution independent of the Cortex-A8 core. Its memory subsystem integrates a 16-bit DDR3/DDR3L controller (400-MHz clock, 800-MHz data rate), GPMC for NAND/NOR/SRAM, and OCMC RAM with retention support.

Power management includes SmartReflex™ Class 2B adaptive voltage scaling (AVS), dynamic voltage-frequency scaling (DVFS), and five ADPLLs generating clocks for MPU, DDR, USB, peripherals, and GFX domains. The device supports secure boot via optional crypto accelerators (AES, SHA, RNG) and features JTAG/cJTAG debug interfaces for Cortex-A8, PRCM, and PRU-ICSS.

FAQ

What is the maximum operating frequency of the AM3358BZCZ100?

The AM3358BZCZ100 operates at a fixed 1000-MHz CPU frequency under its highest OPP (Operating Performance Point). This frequency is guaranteed across the full industrial temperature range (–40°C to 105°C) and supported by SmartReflex™ Class 2B adaptive voltage scaling to maintain stability under varying thermal and process conditions. The AM3358BZCZ100 does not support lower OPPs like some sibling variants.

Does the AM3358BZCZ100 include an integrated graphics accelerator?

Yes, the AM3358BZCZ100 integrates the PowerVR SGX530 3D graphics engine, delivering up to 20 million polygons per second. It supports industry-standard APIs including OpenGL ES 1.1/2.0 and OpenMAX, enabling hardware-accelerated GUI rendering for HMIs without burdening the Cortex-A8 CPU. This graphics capability is confirmed in the AM335x device comparison table and functional block diagram.

How many Ethernet ports does the AM3358BZCZ100 support, and what interfaces are available?

The AM3358BZCZ100 supports two independent Gigabit Ethernet MACs with integrated switch functionality. Each port supports MII, RMII, and RGMII physical layer interfaces, plus MDIO for PHY management. Both MACs implement IEEE 1588v1 Precision Time Protocol for time-synchronized industrial networking - a key differentiator for motion control and distributed I/O systems.

What industrial communication protocols are supported by the PRU-ICSS in the AM3358BZCZ100?

The PRU-ICSS in the AM3358BZCZ100 natively supports EtherCAT®, PROFINET, EtherNet/IP™, PROFIBUS, Ethernet Powerlink, and Sercos protocols. These are implemented in firmware running on the dual 200-MHz PRU cores, enabling deterministic real-time execution independent of the main Cortex-A8 processor and Linux OS scheduler.

What is the package type and ball count for the AM3358BZCZ100?

The AM3358BZCZ100 uses a 324-ball NFBGA package with ZCZ suffix, featuring a 0.80-mm ball pitch and 15.0 mm × 15.0 mm body size. This package is mechanically and electrically identical to other ZCZ-suffixed AM335x variants (e.g., AM3359BZCZ100), enabling drop-in compatibility in existing PCB designs targeting the 324-pin footprint.
