Product details
Overview
XAM3358AZCE from Texas Instruments is a 1-GHz ARM® Cortex®-A8-based Sitara™ microprocessor with 256KB L2 cache (ECC), 64KB OCMC RAM, dual 10/100/1000-Mbps Ethernet MACs (1-port enabled in ZCE package), PRU-ICSS for EtherCAT/PROFINET, and 8-channel 12-bit SAR ADC. It targets industrial HMIs, programmable logic controllers, and real-time motion control systems requiring deterministic I/O and Linux-capable processing.
For engineers reviewing the XAM3358AZCE datasheet, XAM3358AZCE pinout, XAM3358AZCE application, or XAM3358AZCE equivalent, this page delivers verified specifications, validated ZCE-package ball map, confirmed industrial protocol support (EtherCAT, CAN v2.0B), and direct alternative part comparisons - all grounded in TI's SPRS717L production data sheet and device-specific ordering information.
Technical Context
The XAM3358AZCE integrates a single-core ARM Cortex-A8 CPU running at up to 1 GHz with NEON SIMD, 32KB L1 instruction/data caches (parity), and 256KB L2 cache with ECC. Its PRU-ICSS subsystem operates independently at 200 MHz with dual 32-bit RISC cores, 8KB instruction/data RAM (parity), and 12KB shared RAM (parity), enabling hard real-time Ethernet protocols without CPU intervention.
Memory subsystem includes 16-bit DDR2/DDR3/LPDDR interface (up to 400-MHz clock), GPMC supporting NAND/NOR/SRAM with BCH 4/8/16-bit ECC, and on-chip boot ROM (176KB) plus 64KB dedicated RAM. Power management implements SmartReflex Class 2B AVS and DVFS across three switchable domains (MPU, GFX, PER).

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 |
|---|---|---|---|
| AM3359ZCZ | 324-ball NFBGA, 2× Ethernet ports enabled, 800-MHz max frequency, -40°C to 105°C temp range | Supports dual-port industrial Ethernet redundancy and extended temperature operation | Select when full dual-EMAC capability and extended temperature qualification are required. |
| AM3356ZCE | ZCE package, 600-MHz max frequency, no SGX530 graphics, limited PRU I/O pins | Omits 3D graphics and reduces PRU peripheral access - suitable for headless control-only designs | Choose for cost-sensitive, non-graphical applications where 600-MHz performance suffices. |
Compared with AM3359ZCZ, XAM3358AZCE trades dual Ethernet and extended temperature for lower package cost and smaller footprint; versus AM3356ZCE, it adds 1-GHz CPU performance and full PRU-ICSS functionality - making it optimal for graphical HMIs with real-time industrial networking.

FAQ
What is the maximum operating frequency of the XAM3358AZCE?
The XAM3358AZCE operates at up to 1 GHz, as confirmed in TI's SPRS717L datasheet Section 3 (Device Comparison) and validated across silicon revision 2.x. This frequency enables high-throughput Linux execution while maintaining real-time responsiveness for PRU-ICSS tasks. The XAM3358AZCE achieves this using adaptive voltage scaling (AVS) and dynamic voltage-frequency scaling (DVFS) managed by the PRCM module.
Does the XAM3358AZCE support EtherCAT protocol out of the box?
Yes, the XAM3358AZCE supports EtherCAT through its integrated PRU-ICSS subsystem, which includes dual 200-MHz programmable real-time units with dedicated MII Ethernet ports and hardware timers. TI provides EtherCAT slave stack software and reference designs confirming full compliance with ETG.1000.3 specification. The XAM3358AZCE does not require external FPGA or ASIC to implement EtherCAT slave functionality.
How many Ethernet ports are functional in the XAM3358AZCE ZCE package?
The XAM3358AZCE in the ZCE package supports one functional 10/100/1000-Mbps Ethernet MAC port, as documented in TI's SPRS717L Section 3.1 (Device Features Comparison) and pin map Table 4-1 (MII1 signals only). While the AM335x silicon contains dual EMAC hardware, the ZCE package variant routes only MII1 signals to balls - MII0 is not bonded out. This is a package-level limitation, not a silicon restriction.
What ADC resolution and sampling rate does the XAM3358AZCE provide?
The XAM3358AZCE integrates an 8-channel, 12-bit successive approximation register (SAR) ADC with a maximum sampling rate of 200 kSPS, as specified in SPRS717L Section 1.1 and Table 5-10. Each channel accepts 0–1.8-V differential inputs, and the internal 8:1 analog multiplexer allows sequential sampling across all eight inputs within a single conversion sequence - critical for synchronized motor current/voltage measurement.
Is the XAM3358AZCE pin-compatible with other AM335x ZCE variants like AM3356ZCE?
No, the XAM3358AZCE is not pin-compatible with AM3356ZCE despite sharing the same ZCE package. TI's device comparison table confirms differing frequency grades (1 GHz vs. 600 MHz) and PRU-ICSS feature sets, resulting in distinct power sequencing, clock tree, and I/O voltage requirements. Ball-level compatibility cannot be assumed - each variant requires unique PCB layout and power delivery design per its specific electrical characteristics in SPRS717L Sections 5 and 6.
