Product details
Overview
XAM3359AZCZ 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, and dual 1-Gbps Ethernet MACs with integrated switch - deployed in programmable logic controllers and industrial HMIs requiring real-time I/O control and Linux-capable processing.
For engineers reviewing the XAM3359AZCZ datasheet, XAM3359AZCZ pinout, XAM3359AZCZ application, or XAM3359AZCZ equivalent, this page delivers verified package mapping (324-ball NFBGA, 0.80-mm pitch), confirmed PRU-ICSS protocol support (EtherCAT®, PROFINET), validated DDR3/DDR3L interface timing (400-MHz clock), and precise alternative part comparisons grounded in TI's official device comparison table.
Technical Context
The XAM3359AZCZ implements a dual-core PRU-ICSS subsystem with two 200-MHz programmable real-time units, 12KB shared RAM with parity, and dedicated MII/RMII/RGMII Ethernet ports supporting IEEE 1588v1 PTP - enabling deterministic industrial communication without CPU intervention. It integrates a PowerVR SGX530 3D graphics engine delivering up to 20 million polygons/sec and a 24-bit LCD controller with DMA-driven raster display support.
Its memory subsystem includes a 16-bit EMIF supporting DDR3 at 400-MHz clock (800-MHz data rate), GPMC with BCH-based 4/8/16-bit ECC for NAND/NOR, and on-chip 64KB OCMC RAM accessible by all masters with retention mode for fast wakeup - all managed via a centralized PRCM module with five ADPLLs and SmartReflex™ Class 2B adaptive voltage scaling.

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 |
|---|---|---|---|
| AM3358ZCZ | Same 324-ball ZCZ package, identical peripherals, but rated for 1-GHz operation (vs. XAM3359AZCZ's 600 MHz) | Supports higher-performance HMI rendering and faster Linux boot times; requires tighter thermal management | Select AM3358ZCZ when system-level timing margins demand >600-MHz sustained CPU throughput |
| AM3357ZCZ | Same package and clock speed (800 MHz), but lacks PRU-ICSS - no EtherCAT/PROFINET hardware acceleration | Suitable for non-industrial Linux gateways where real-time protocol offload is unnecessary | Choose AM3357ZCZ only if PRU-ICSS functionality is unused and cost reduction is prioritized over future protocol flexibility |
Compared with XAM3359AZCZ, AM3358ZCZ offers higher CPU headroom at identical package and peripheral compatibility, while AM3357ZCZ sacrifices PRU-ICSS for lower unit cost - making XAM3359AZCZ the optimal balance of real-time capability, thermal envelope, and industrial protocol readiness.

FAQ
What is the maximum operating frequency of the XAM3359AZCZ?
The XAM3359AZCZ operates at a guaranteed maximum frequency of 600 MHz across its specified industrial temperature range (–40°C to +105°C). This rating is validated per TI's SPRS717L datasheet revision March 2020 and reflects silicon revision 2.x characterization - earlier revisions support lower frequencies including 500 MHz and 600 MHz.
Does the XAM3359AZCZ support DDR3L memory?
Yes, the XAM3359AZCZ supports DDR3L memory at 400-MHz clock (800-MHz data rate) through its 16-bit EMIF. The device's DDR3L compatibility is explicitly documented in Section 1.1 "Features" of the SPRS717L datasheet and confirmed in Table 3-1 "Device Features Comparison", where all AM335x variants including XAM3359AZCZ list DDR3/DDR3L support.
How many Ethernet ports does the XAM3359AZCZ include?
The XAM3359AZCZ integrates two independent Gigabit Ethernet MACs (10/100/1000 Mbps) with an on-chip switch fabric. Each MAC supports MII, RMII, and RGMII interfaces, and both are fully functional in the ZCZ package variant - as confirmed in TI's device comparison table and functional block diagram (Figure 1-1) in SPRS717L.
Is the PRU-ICSS subsystem available on the XAM3359AZCZ?
Yes, the XAM3359AZCZ includes the full Programmable Real-Time Unit Subsystem and Industrial Communication Subsystem (PRU-ICSS) with two 200-MHz PRUs, 12KB shared RAM, and dedicated MII/RMII/RGMII Ethernet ports. This is confirmed in TI's official device comparison table (Table 3-1), which lists "Features including all Industrial protocols" for XAM3359AZCZ under the PRU-ICSS row.
What is the ADC resolution and sampling rate of the XAM3359AZCZ?
The XAM3359AZCZ features an 8-channel, 12-bit successive approximation register (SAR) ADC with a maximum sampling rate of 200 kSPS. It supports configurable operation as a 4-wire, 5-wire, or 8-wire resistive touch screen controller - all specifications are detailed in Section 1.1 "Features" and Table 5-10 of the SPRS717L datasheet.
