Texas Instruments AM3356BZCZA80

Overview

AM3356BZCZA80 from Texas Instruments is a 600-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), 8-channel 12-bit SAR ADC, dual 10/100/1000-Mbps Ethernet MACs (ZCZ package), and PRU-ICSS supporting EtherCAT and PROFINET - deployed in industrial HMIs, programmable logic controllers, and connected vending systems.

For engineers reviewing the AM3356BZCZA80 datasheet, AM3356BZCZA80 pinout, AM3356BZCZA80 application, or AM3356BZCZA80 equivalent, this page delivers verified SoC identity, validated ZCZ-package pin mapping, confirmed 600-MHz OPP, PRU-ICSS protocol support scope, and real-world industrial interface constraints - all extracted from TI SPRS717L (Rev. L, March 2020) and device-specific orderable data.

Technical Context

The AM3356BZCZA80 implements a dual-core programmable real-time unit subsystem (PRU-ICSS) with two 200-MHz RISC processors, 12KB shared RAM (parity), and dedicated MII/Ethernet PHY interfaces for industrial protocols including EtherCAT and PROFINET. It integrates PowerVR SGX530 graphics acceleration, IEEE 1588v1 PTP support, and hardware crypto accelerators (AES, SHA, RNG).

Its memory subsystem includes 16-bit DDR3/DDR3L/DDR2/mDDR EMIF (400-MHz clock), GPMC with BCH-based ECC for NAND/NOR, and 64KB OCMC RAM accessible by all masters. The device uses SmartReflex™ Class 2B adaptive voltage scaling and supports DVFS across five operating performance points (OPPs), with AM3356BZCZA80 specifically rated at 600 MHz.

FAQ

What is the maximum operating frequency of the AM3356BZCZA80?

The AM3356BZCZA80 is factory-binned and characterized for stable operation at 600 MHz across the –40°C to +105°C temperature range. This frequency corresponds to Operating Performance Point (OPP) OPP300 in TI's AM335x documentation, and is validated with DDR3-800 and full peripheral enablement per SPRS717L Section 5.4.

Does the AM3356BZCZA80 support secure boot functionality?

AM3356BZCZA80 supports optional secure boot through TI's custom part engagement process. When enabled, it performs cryptographic verification of the first-stage bootloader using AES-256 and SHA-256 hardware accelerators, preventing unauthorized firmware execution - a capability confirmed in SPRS717L Section 1.1 and Section 3.1.

Which Ethernet interfaces are available on the AM3356BZCZA80?

The AM3356BZCZA80 integrates two independent 10/100/1000-Mbps Ethernet MACs with integrated switch fabric. Each supports MII, RMII, and RGMII physical layer interfaces, plus IEEE 1588v1 Precision Time Protocol for time-synchronized industrial networking - all documented in SPRS717L Section 1.1 and Section 7.6.

Can the AM3356BZCZA80 drive a high-resolution LCD display?

Yes, the AM3356BZCZA80 includes a 24-bit RGB LCD controller supporting resolutions up to 2048×2048 with a 126-MHz pixel clock. Its integrated DMA engine pulls frame buffer data directly from external DDR memory without CPU intervention, enabling smooth video playback and GUI rendering as specified in SPRS717L Section 1.1 and Section 7.10.

What package type and ball count does the AM3356BZCZA80 use?

AM3356BZCZA80 uses a 324-ball NFBGA (ZCZ) package with 0.80-mm ball pitch and 15.0 mm × 15.0 mm body size. This matches TI's official packaging designation in SPRS717L Section 1.2 and Device Information table, and is distinct from the 298-ball ZCE variant used in lower-I/O configurations.
