Product details
Overview
AM3358ZCZD72 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, PRU-ICSS for EtherCAT/PROFINET, and 8-channel 12-bit SAR ADC. It supports DDR3/DDR3L at 800-MHz data rate, features 256KB L2 cache with ECC, and targets industrial HMI, programmable logic controllers, and connected automation gateways.
For engineers reviewing the AM3358ZCZD72 datasheet, AM3358ZCZD72 pinout, AM3358ZCZD72 application, or AM3358ZCZD72 equivalent, key selection criteria include its 1-GHz CPU frequency, dual gigabit Ethernet with IEEE 1588v1 PTP support, PRU-ICSS real-time protocol offload capability, and industrial temperature grade (–40°C to 90°C) in the 324-ball NFBGA package.
Technical Context
The AM3358ZCZD72 implements a dual-core real-time subsystem via two independent 200-MHz PRUs with 8KB instruction/data RAM each, enabling deterministic I/O handling and industrial protocol stack execution separate from the Cortex-A8 core. Its PRU-ICSS includes two MII Ethernet ports, one MDIO, one UART, and eCAP/eHRPWM peripherals directly accessible by PRU firmware.
Power management integrates five ADPLLs for clock generation, SmartReflex™ Class 2B adaptive voltage scaling, and dynamic voltage-frequency scaling (DVFS) across three switchable domains (MPU, GFX, PER). The device boots from external NAND/NOR/SD via GPMC or MMC interfaces, with on-chip 176KB ROM and 64KB RAM for secure boot and early initialization.
