Texas Instruments AM3359ZCZD72

Overview

AM3359ZCZD72 from Texas Instruments is a 600-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), PRU-ICSS subsystem for industrial Ethernet protocols (EtherCAT, PROFINET), dual 1-Gbps Ethernet MACs with integrated switch, and 8-channel 12-bit SAR ADC. It integrates PowerVR SGX530 3D graphics, USB 2.0 DRD ports, and supports DDR3/DDR3L memory at 800-MHz data rate in industrial temperature range (–40°C to 105°C).

For engineers reviewing the AM3359ZCZD72 datasheet, AM3359ZCZD72 pinout, AM3359ZCZD72 application, or AM3359ZCZD72 equivalent, this page delivers verified technical context, package mapping, real-time I/O capabilities, industrial protocol support, and validated alternative options for embedded control, HMI, and edge gateway designs.

Technical Context

The AM3359ZCZD72 implements a dual-core programmable real-time unit (PRU) subsystem operating at 200 MHz, each with 8KB instruction/data RAM (parity), 12KB shared RAM, and dedicated peripherals including two MII Ethernet ports, one UART, one eCAP, and MDIO - enabling deterministic industrial communication offload from the Cortex-A8 core. Its PRU-ICSS is fully independent in clocking and execution.

It features a 16-bit external memory interface supporting DDR3/DDR3L at 400-MHz clock (800-MHz data rate), 1GB address space, and GPMC with NAND/NOR/SRAM support using BCH 4-/8-/16-bit ECC. The device includes IEEE 1588v1 PTP support in both EMACs and hardware crypto accelerators (AES, SHA, RNG) for secure boot and runtime encryption.

Key Specifications

FAQ

What is the maximum DDR3 data rate supported by AM3359ZCZD72?

The AM3359ZCZD72 supports DDR3/DDR3L memory at 400-MHz clock frequency, delivering an 800-Mbps data rate on its 16-bit bus. This is confirmed in Section 1.1 of SPRS717L Rev L and validated in the EMIF timing specifications (Section 7.7). The interface supports one x16 or two x8 memory device configurations with full 1GB addressable space.

Does AM3359ZCZD72 include hardware crypto acceleration?

Yes, AM3359ZCZD72 integrates dedicated hardware accelerators for AES-128/256 encryption/decryption, SHA-1/256 hashing, and a true random number generator (TRNG). These modules are documented in Section 1.1 (Security) and Section 5.10 of SPRS717L Rev L, enabling secure boot and TLS offload without CPU overhead.

Can AM3359ZCZD72 run EtherCAT and PROFINET simultaneously?

Yes, AM3359ZCZD72's PRU-ICSS contains two independent MII Ethernet ports, allowing concurrent EtherCAT master operation on MII1 and PROFINET device operation on MII2 - both with hardware timestamping and zero-CPU-intervention frame processing, as specified in Section 1.1 and PRU-ICSS documentation (SPRUIJ5).

What is the operating temperature range for AM3359ZCZD72?

AM3359ZCZD72 is rated for industrial operation from –40°C to +105°C, as stated in Table 3-1 (Device Features Comparison) and Section 9.2 (Packaging Information) of SPRS717L Rev L. This rating applies specifically to ZCZ-package variants like AM3359ZCZD72 and is validated across all silicon revisions.

How many analog input channels does AM3359ZCZD72 support?

AM3359ZCZD72 includes an 8-channel 12-bit SAR ADC capable of 200 kSPS sampling, with inputs AIN0–AIN7 multiplexed through an 8:1 analog switch. It can be configured as a 4-wire, 5-wire, or 8-wire resistive touch screen controller - all detailed in Section 1.1 (Peripherals) and Section 5.10 of SPRS717L Rev L.
