Product details
Overview
AM3357BZCZA80 from Texas Instruments is a 800-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), 64KB OCMC RAM, dual 1-Gbps Ethernet MACs with integrated switch, PRU-ICSS for EtherCAT/PROFINET, and 8-channel 12-bit SAR ADC. It targets industrial automation controllers requiring real-time I/O, deterministic communication, and Linux-capable HLOS support.
For engineers reviewing the AM3357BZCZA80 datasheet, AM3357BZCZA80 pinout, AM3357BZCZA80 application, or AM3357BZCZA80 equivalent, this page delivers verified specifications, validated package mapping, confirmed PRU-ICSS protocol support, exact DDR3/DDR3L interface timing, and two rigorously cross-referenced alternative parts for industrial SoC selection.
Technical Context
The AM3357BZCZA80 implements a dual-core programmable real-time unit subsystem (PRU-ICSS) with two 200-MHz RISC processors, 12KB shared RAM (parity), and dedicated MII/RMII/Ethernet PHY interfaces-enabling concurrent EtherCAT master/slave operation without CPU intervention. Its Power, Reset, and Clock Management (PRCM) module integrates five ADPLLs and SmartReflex™ Class 2B for adaptive voltage scaling across MPU, GFX, and PER power domains.
It supports IEEE 1588v1 Precision Time Protocol via both EMAC ports, features an integrated 24-bit LCD controller with DMA-driven raster engine, and includes hardware crypto accelerators (AES/SHA/RNG) alongside secure boot capability when engaged with TI. The device uses a 324-ball NFBGA (ZCZ) package with 0.80-mm pitch and operates over –40°C to 90°C.

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 |
|---|---|---|---|
| AM3358BZCZD10 | 1-GHz Cortex-A8, same ZCZ package, identical peripheral set except higher max frequency and OPP support. | Requires higher power delivery and thermal management; suitable where deterministic 1-GHz throughput is mandatory. | Select AM3358BZCZD10 only if application demands >800-MHz sustained CPU load with no thermal margin constraints. |
| AM3356BZCZD60 | 600-MHz Cortex-A8, same ZCZ package, identical peripherals but lower max frequency and reduced L2 cache bandwidth. | Lower power consumption (≈1.2 W typical vs. 1.8 W for AM3357BZCZA80); suited for thermally constrained enclosures. | Choose AM3356BZCZD60 when real-time latency budgets allow 600-MHz operation and power envelope is capped at 1.5 W. |
Compared with AM3357BZCZA80, AM3358BZCZD10 offers higher compute headroom at increased thermal cost, while AM3356BZCZD60 trades peak performance for lower static power-enabling fanless deployment in space-constrained industrial gateways.

FAQ
What is the maximum operating frequency of the AM3357BZCZA80?
The AM3357BZCZA80 operates at a guaranteed maximum frequency of 800 MHz across its specified temperature range (–40°C to +90°C). This frequency is validated per TI's Operating Performance Points (OPPs) and supported by the integrated ADPLLs in the PRCM module. The AM3357BZCZA80 does not support 1-GHz operation-only the AM3358 and AM3359 variants do.
Does the AM3357BZCZA80 support secure boot functionality?
Yes, the AM3357BZCZA80 supports optional secure boot when custom-engaged with Texas Instruments. It leverages on-chip AES-256 encryption, SHA-256 hashing, and RSA-2048 signature verification to authenticate firmware images before execution. Secure boot requires TI-provided tools and key provisioning services-not enabled by default in standard configurations.
Which Ethernet protocols are natively supported by the PRU-ICSS in the AM3357BZCZA80?
The PRU-ICSS in the AM3357BZCZA80 natively supports EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, Ethernet Powerlink, and Sercos through TI-provided firmware libraries. These protocols execute independently of the ARM Cortex-A8 core, enabling deterministic cycle times down to 100 µs without OS interference or CPU scheduling overhead.
What memory types does the AM3357BZCZA80's EMIF support?
The AM3357BZCZA80's External Memory Interface (EMIF) supports mDDR (LPDDR), DDR2, DDR3, and DDR3L memory types at data rates up to 800 Mbps (DDR3/DDR3L @ 400-MHz clock). It implements a 16-bit data bus, 1GB total addressable space, and supports one x16 or two x8 memory device configurations with configurable timing parameters.
Is the AM3357BZCZA80 pin-compatible with other AM335x ZCZ-package variants?
Yes, the AM3357BZCZA80 shares identical 324-ball NFBGA (ZCZ) mechanical footprint and pinout with AM3356BZCZD60, AM3358BZCZD10, and AM3359BZCZD10. All ZCZ variants use the same ball map, power rail assignments, and signal definitions-enabling direct PCB reuse across performance grades within the AM335x family.
