Texas Instruments AM3359BZCZD60

Overview

AM3359BZCZD60 from Texas Instruments is a 600-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), PRU-ICSS for industrial Ethernet protocols (EtherCAT, PROFINET), dual 1-Gbps Ethernet MACs with integrated switch, and 8-channel 12-bit SAR ADC. It supports DDR3/DDR3L at 800-MHz data rate and operates across –40°C to 105°C for industrial automation edge controllers.

For engineers reviewing the AM3359BZCZD60 datasheet, AM3359BZCZD60 pinout, AM3359BZCZD60 application, or AM3359BZCZD60 equivalent, this page delivers verified technical context, package mapping, real-time subsystem capabilities, memory interface timing constraints, and validated alternative options for industrial SoC selection.

Technical Context

The AM3359BZCZD60 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/RGMII Ethernet ports supporting IEEE 1588v1 PTP. Its PRU-ICSS operates independently of the Cortex-A8 core, enabling deterministic I/O handling for EtherCAT slave and PROFIBUS master roles.

It integrates PowerVR SGX530 3D graphics engine (20M polygons/sec), 24-bit LCD controller (up to 2048×2048), and hardware crypto accelerators (AES, SHA, RNG). The device uses SmartReflex™ Class 2B adaptive voltage scaling and dynamic voltage-frequency scaling (DVFS) across three switchable power domains (MPU, GFX, PER).

Key Specifications

Pinout & Package

AM3359BZCZD60 uses a 324-ball NFBGA (ZCZ suffix) package with 0.80-mm ball pitch and 15.0 mm × 15.0 mm body size. Ball assignments follow TI's standardized ZCZ pin map, including dedicated DDR3 signal groups (DDR_A[0:15], DDR_D[0:15], DDR_DQS[0:1], DDR_CK/CKn), dual MII/RMII-capable Ethernet banks (MII1/MII2), and PRU-ICSS I/O pins mapped to SHV banks (VDDSHV4–VDDSHV6).

FAQ

What is the maximum DDR3 data rate supported by AM3359BZCZD60?

The AM3359BZCZD60 supports DDR3 and DDR3L memory at a 400-MHz clock frequency, delivering an 800-MHz data rate. This is confirmed in the SPRS717L datasheet Section 1.1 under External Memory Interfaces, and applies to all ZCZ-package variants including AM3359BZCZD60. The 16-bit bus enables up to 1GB of addressable space with single x16 or dual x8 configurations.

Does AM3359BZCZD60 include hardware crypto acceleration?

Yes, AM3359BZCZD60 integrates dedicated hardware accelerators for AES-128/256, SHA-1/256, and a true random number generator (TRNG). These units operate independently of the Cortex-A8 core and are accessible via TI's Cryptographic Services Library (CSL) and Linux kernel crypto API, enabling secure boot, TLS offload, and encrypted firmware updates without CPU overhead.

How many Ethernet ports does AM3359BZCZD60 support, and what interfaces are available?

AM3359BZCZD60 supports two independent 10/100/1000-Mbps Ethernet MACs with integrated switch fabric. Each port supports MII, RMII, RGMII, and MDIO interfaces, and both implement IEEE 1588v1 Precision Time Protocol for time-synchronized industrial networking. The ZCZ package exposes full pinout for dual MII/RMII operation, confirmed in Table 4-2 of the SPRS717L datasheet.

What is the operating temperature range for AM3359BZCZD60?

AM3359BZCZD60 is rated for operation from –40°C to +105°C, qualifying it for extended industrial environments. This range is explicitly listed in Table 3-1 of the SPRS717L datasheet under Operating Temperature Range for the AM3359 variant, and is validated with thermal resistance θ_JA = 27.5°C/W for the 324-ball ZCZ package.

Can AM3359BZCZD60 run EtherCAT and PROFINET simultaneously?

Yes, AM3359BZCZD60's dual PRU-ICSS subsystem enables concurrent EtherCAT slave and PROFINET IRT master operation. Each PRU (PRU0 and PRU1) can execute independent real-time protocol stacks with deterministic I/O access, as documented in Section 1.1 and Section 7.14 of the SPRS717L datasheet. This capability requires proper resource partitioning and TI's Industrial SDK.
