Product details
Overview
AM3359BZCZD80 from Texas Instruments is a 600-MHz ARM Cortex-A8-based Sitara™ processor with integrated PRU-ICSS for industrial Ethernet protocols, 256KB L2 cache with ECC, 8-channel 12-bit SAR ADC, dual 1-Gbps Ethernet MACs with switch, and hardware crypto acceleration (AES/SHA/RNG). It targets industrial automation controllers requiring real-time I/O, deterministic communication, and Linux-capable HLOS support.
For engineers reviewing the AM3359BZCZD80 datasheet, AM3359BZCZD80 pinout, AM3359BZCZD80 application, or AM3359BZCZD80 equivalent, this page delivers verified technical context, package mapping to NFBGA-324 (ZCZ), confirmed pin functions, real-world use cases in EtherCAT motion control and smart HMIs, and validated alternative parts with documented functional and thermal differences.
Technical Context
The AM3359BZCZD80 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 supporting EtherCAT and PROFINET. Its MPU subsystem runs at 600 MHz with NEON SIMD, 32KB L1 instruction/data caches (parity-protected), and 256KB L2 cache (ECC-protected).
It integrates a 24-bit LCD controller with DMA-driven raster engine, 3× eHRPWM modules (16-bit time-base, dual-edge symmetric/asymmetric outputs), and a GPMC supporting NAND/NOR/SRAM with 4-/8-/16-bit BCH ECC. Power management includes SmartReflex Class 2B AVS and DVFS across three switchable domains (MPU, GFX, PER).

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based industrial processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3358BZCZD100 | 1-GHz CPU frequency, identical ZCZ package and peripheral set; higher thermal dissipation (1.2 W typical vs. 0.95 W). | Required for compute-intensive tasks like video analytics or multi-threaded real-time control where 600-MHz headroom is insufficient. | Select AM3358BZCZD100 when application demands >1200 MIPS sustained performance and board-level thermal design accommodates higher junction temperature. |
| AM3356BZCZD60 | 600-MHz CPU but ZCE package (298-pin, 0.65-mm pitch); lacks second Ethernet MAC and PRU-ICSS full feature set (limited I/O pinout). | Suitable for cost-sensitive, space-constrained designs where single Ethernet port and basic industrial protocols suffice. | Choose AM3356BZCZD60 only if PCB layout constraints require smaller footprint and application does not require dual MII or full EtherCAT stack support. |

FAQ
What is the maximum operating frequency of the AM3359BZCZD80?
The AM3359BZCZD80 operates at a guaranteed maximum frequency of 600 MHz across its –40°C to +105°C industrial temperature range. This frequency is silicon-qualified and supported by TI's OPP (Operating Performance Point) tables, ensuring stable operation under worst-case voltage and thermal conditions without derating.
Does the AM3359BZCZD80 support secure boot functionality?
Yes, the AM3359BZCZD80 supports optional secure boot using hardware crypto accelerators (AES/SHA/RNG) and one-time programmable fuses. Secure boot implementation requires custom part engagement with Texas Instruments and is enabled via fuse programming during manufacturing - not configurable in-field.
How many Ethernet interfaces does the AM3359BZCZD80 provide, and what are their capabilities?
The AM3359BZCZD80 integrates two independent Gigabit Ethernet MACs with an internal switch, each supporting MII, RMII, and RGMII interfaces. Both ports implement IEEE 1588v1 Precision Time Protocol for sub-microsecond timestamping and can operate concurrently for redundant or segmented network topologies.
What package type and ball count does the AM3359BZCZD80 use?
The AM3359BZCZD80 uses the ZCZ package: a 324-ball NFBGA with 0.80-mm ball pitch and 15.0 mm × 15.0 mm body size. This package features via-channel construction for improved signal integrity and thermal dissipation in industrial PCB layouts.
Can the AM3359BZCZD80 directly drive a 24-bit RGB display without external components?
Yes, the AM3359BZCZD80 includes an integrated 24-bit LCD controller with raster engine and DMA support. It drives passive or active matrix panels up to 2048 × 2048 resolution at 126-MHz pixel clock, requiring only external LVDS or RGB timing interface components - no external frame buffer or GPU is needed.
