Texas Instruments AM3358BZCZ30

Overview

AM3358BZCZ30 from Texas Instruments is a 1-GHz ARM Cortex-A8-based Sitara™ processor with integrated PowerVR SGX530 3D graphics engine, PRU-ICSS for industrial Ethernet protocols (EtherCAT, PROFINET), and dual 1-Gbps Ethernet MACs with integrated switch. It features 256KB L2 cache with ECC, 8-channel 12-bit SAR ADC, and supports DDR3/DDR3L at 800-MHz data rate. Used in industrial HMIs, programmable logic controllers, and embedded vision gateways.

For engineers reviewing the AM3358BZCZ30 datasheet, AM3358BZCZ30 pinout, AM3358BZCZ30 application, or AM3358BZCZ30 equivalent, key selection criteria include its 1-GHz CPU frequency, ZCZ 324-ball NFBGA package with 0.80-mm pitch, PRU-ICSS real-time subsystem, dual gigabit Ethernet with IEEE 1588v1 PTP support, and industrial temperature range (–40°C to 90°C).

Technical Context

The AM3358BZCZ30 implements a dual-core programmable real-time unit subsystem (PRU-ICSS) with two 200-MHz RISC processors, 12KB shared RAM, and dedicated peripherals including dual MII Ethernet ports, UART, eCAP, and MDIO - enabling deterministic industrial protocol stacks independent of the ARM 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 for fast boot and low-latency access.

Power management includes five ADPLLs for domain-specific clock generation, SmartReflex™ Class 2B adaptive voltage scaling, and three switchable power domains (MPU, GFX, PER). The device boots from multiple sources (MMC/SD, SPI NOR, NAND, UART) and supports secure boot via optional TI engagement, with crypto accelerators for AES, SHA, and RNG.

FAQ

What is the maximum operating frequency of the AM3358BZCZ30?

The AM3358BZCZ30 is rated for up to 1 GHz operation per the official TI datasheet SPRS717L. This frequency is validated across the full industrial temperature range (–40°C to +90°C) and supported by the on-chip ADPLLs and SmartReflex™ voltage scaling. At 1 GHz, the AM3358BZCZ30 delivers 2000 MIPS performance with NEON SIMD acceleration for compute-intensive tasks like protocol stack processing or graphics rendering.

Does the AM3358BZCZ30 support IEEE 1588 Precision Time Protocol?

Yes, the AM3358BZCZ30 supports IEEE 1588v1 Precision Time Protocol (PTP) through its dual Ethernet MACs. Each port provides hardware timestamping for sync, delay_req, and pdelay_req frames, enabling sub-microsecond time synchronization in industrial motion control and distributed I/O systems. The PTP implementation is integrated into the CPSW switch subsystem and accessible via Linux PTP stack drivers.

What package type and ball count does the AM3358BZCZ30 use?

The AM3358BZCZ30 uses a 324-ball NFBGA package (suffix ZCZ) with 0.80-mm ball pitch and 15.0 mm × 15.0 mm body size. This package is mechanically and electrically compatible with other ZCZ-suffixed AM335x variants (e.g., AM3359BZCZ100), enabling footprint reuse across performance grades. Thermal vias beneath the die pad are recommended for industrial thermal management.

Can the AM3358BZCZ30 run real-time industrial protocols like EtherCAT?

Yes, the AM3358BZCZ30 supports EtherCAT, PROFINET, and other industrial protocols via its Programmable Real-Time Unit Subsystem (PRU-ICSS). The dual 200-MHz PRUs execute protocol stacks with deterministic timing independent of the ARM Cortex-A8 core, enabling hard real-time EtherCAT slave operation with cycle times down to 100 µs. TI provides certified EtherCAT slave stack binaries and reference designs for AM3358BZCZ30.

What memory interfaces does the AM3358BZCZ30 support?

The AM3358BZCZ30 supports mDDR/LPDDR, DDR2, DDR3, and DDR3L via its 16-bit EMIF controller (up to 400-MHz clock, 800-MHz data rate), plus asynchronous GPMC for NAND/NOR flash and SRAM. It also includes 64KB of on-chip OCMC RAM for low-latency code/data storage and 176KB boot ROM. External memory configurations support one x16 or two x8 devices, with ECC support via BCH/Hamming algorithms.
