For engineers reviewing the AM3358BZCZA100 datasheet, AM3358BZCZA100 pinout, AM3358BZCZA100 application, or AM3358BZCZA100 equivalent, this page delivers verified SoC-level specifications, validated package mapping, confirmed PRU-ICSS protocol support, real-time peripheral timing constraints, and direct alternative part comparisons for industrial embedded design.
Technical Context
The AM3358BZCZA100 implements a single-core ARM Cortex-A8 CPU running at 1 GHz with NEON SIMD, 32KB/32KB L1 I/D cache (parity), and 256KB L2 cache (ECC). It integrates PowerVR SGX530 graphics (20M polygons/sec), dual EMACs supporting MII/RMII/RGMII, and a dedicated PRU-ICSS subsystem with two 200-MHz RISC cores, 12KB shared RAM, and hardware-accelerated industrial Ethernet interfaces.
Its memory subsystem supports DDR3/DDR3L at 400 MHz (800 Mbps data rate) via 16-bit EMIF, GPMC with NAND/NOR/SRAM support including BCH 4/8/16-bit ECC, and on-chip boot ROM (176KB) plus 64KB dedicated RAM. The device operates across 0°C to 90°C and uses 1.8-V/3.3-V I/O supplies with SmartReflex Class 2B adaptive voltage scaling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based industrial SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3359BZCZD80 | Same ZCZ package, 800-MHz max frequency, no SGX530 graphics accelerator | Suitable for headless control applications where GUI rendering is unnecessary | Select when cost sensitivity outweighs need for 3D UI acceleration and full 1-GHz performance |
| AM4379BZDN80 | ARM Cortex-A9 @ 1 GHz, dual-core, PRU-ICSS v2, 3D graphics, enhanced security (TrustZone) | Supports virtualization, secure boot enforcement, and higher I/O density for next-gen edge gateways | Choose for future-proof designs requiring dual-core redundancy, TrustZone isolation, or extended lifecycle beyond AM335x |
Compared with AM3359BZCZD80, AM3358BZCZA100 delivers full 1-GHz operation and SGX530 graphics for rich UIs; versus AM4379BZDN80, it offers proven qualification for industrial temperature range but lacks TrustZone and dual-core capability - making it optimal for cost-constrained, graphics-enabled single-core control nodes.

The device achieves 2000 MIPS performance at this speed, enabling demanding real-time Linux applications without external co-processors.
Does the AM3358BZCZA100 support IEEE 1588 Precision Time Protocol?
Yes, the AM3358BZCZA100 supports IEEE 1588v1 Precision Time Protocol through its dual Ethernet MACs. Hardware timestamping is implemented in the EMAC peripherals, allowing sub-microsecond clock synchronization accuracy when paired with compliant PHYs and proper PCB layout for RGMII signal integrity.
What package type and ball count does the AM3358BZCZA100 use?
The AM3358BZCZA100 uses a 324-ball NFBGA package (ZCZ suffix), measuring 15.0 mm × 15.0 mm with 0.80-mm ball pitch. This package includes an exposed thermal pad on the underside for efficient heat transfer to the PCB, and is distinct from the 298-ball ZCE variant used in lower-pin-count configurations.
Can the AM3358BZCZA100 run Linux and real-time operating systems?
Yes, the AM3358BZCZA100 is fully supported by Processor SDK Linux® and TI-RTOS, both provided free of charge by Texas Instruments. Its 1-GHz Cortex-A8 core, 256KB L2 cache, and DDR3 interface meet minimum requirements for Yocto Project-based Linux distributions and deterministic real-time task scheduling.
What industrial communication protocols does the PRU-ICSS in the AM3358BZCZA100 support?
The PRU-ICSS in the AM3358BZCZA100 supports EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, and other industrial Ethernet protocols via firmware-loaded state machines. These run independently of the ARM core at 200 MHz, enabling hard real-time response with cycle times down to 100 μs without CPU intervention.
