Product details
Overview
XAM3358ZCE from Texas Instruments is a 1-GHz ARM® Cortex®-A8-based Sitara™ microprocessor with 256KB L2 cache (ECC), 8-channel 12-bit SAR ADC, dual 10/100/1000-Mbps Ethernet MACs (1-port enabled in ZCE package), and PRU-ICSS supporting EtherCAT and PROFINET. It integrates PowerVR SGX530 3D graphics, USB 2.0 DRD, and industrial peripherals for real-time control in programmable logic controllers.
For engineers reviewing the XAM3358ZCE datasheet, XAM3358ZCE pinout, XAM3358ZCE application, or XAM3358ZCE equivalent, this page delivers verified technical context, validated pin functions, confirmed industrial protocol support (EtherCAT, CAN v2.0), and precise package-level feature mapping for ZCE's 298-ball NFBGA layout.
Technical Context
The XAM3358ZCE implements a dual-core PRU-ICSS subsystem with two 200-MHz programmable real-time units, each backed by 8KB instruction RAM and 8KB data RAM (parity-protected), plus 12KB shared RAM. Its MPU subsystem runs at up to 1 GHz with NEON SIMD, 32KB L1 I/D caches (parity), and 256KB L2 cache (ECC).
It supports DDR3/DDR2/mDDR/DDR3L memory via a 16-bit EMIF running at 400 MHz (800 Mbps data rate), and includes GPMC with BCH-based ECC for NAND/NOR flash. The PRU-ICSS provides dedicated MII/Ethernet ports, eCAP/eHRPWM/eQEP modules, and hardware-accelerated crypto (AES/SHA/RNG).

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 MACs fully enabled, higher thermal rating (–40°C to 105°C), no PRU I/O pin limitations. | Required for dual-port industrial Ethernet switch designs or extended-temperature deployments. | Select AM3359ZCZ when full PRU I/O access and dual EMACs are mandatory; XAM3358ZCE remains optimal for cost-sensitive single-EMAC systems. |
| AM3356ZCE | Same 298-ball ZCE package but rated for 600-MHz max frequency, lower power consumption, and reduced L2 cache bandwidth. | Suitable for non-real-time HMI or gateway applications where 1-GHz processing headroom is unnecessary. | Choose AM3356ZCE for thermal-constrained or battery-backed applications needing lower static power; XAM3358ZCE delivers higher deterministic throughput for motion control. |
Compared with AM3359ZCZ, XAM3358ZCE trades dual EMAC availability and extended temperature range for lower package cost and smaller PCB footprint; versus AM3356ZCE, it adds 400-MHz frequency headroom and full 1-GHz OPP support for demanding real-time workloads.

FAQ
What is the maximum operating frequency of the XAM3358ZCE?
The XAM3358ZCE operates at up to 1 GHz under OPP50 conditions per TI SPRS717L datasheet revision L. This frequency is validated for the ZCE package at 0°C to 90°C ambient, with SmartReflex Class 2B adaptive voltage scaling dynamically adjusting core voltage to maintain stability across process and temperature variations. XAM3358ZCE achieves 2000 MIPS at this speed, enabling complex real-time control algorithms in industrial PLCs.
Does the XAM3358ZCE support EtherCAT protocol out of the box?
Yes, the XAM3358ZCE supports EtherCAT through its PRU-ICSS subsystem, which includes dedicated MII Ethernet ports and programmable real-time units capable of executing EtherCAT slave stack firmware with sub-microsecond jitter. TI provides reference implementations and SDKs for EtherCAT, PROFINET, and other industrial protocols - all validated on XAM3358ZCE hardware.
How many Ethernet ports are functional on the XAM3358ZCE?
The XAM3358ZCE features two Ethernet MACs in silicon, but only one (EMAC0) is fully enabled and routed to pins in the ZCE package. EMAC1 is present but not bonded out - confirmed in TI's AM335x device comparison table and ZCE pin map documentation. Designers must use EMAC0 with MII/RMII/RGMII interfaces for industrial Ethernet connectivity.
What ADC capabilities does the XAM3358ZCE provide?
The XAM3358ZCE integrates an 8-channel, 12-bit SAR ADC with 200 kSPS sampling rate and configurable 4-/5-/8-wire resistive touch screen controller mode. All eight analog inputs (AIN0–AIN7) are accessible via dedicated pins and support simultaneous sampling with hardware-triggered conversion sequences - critical for synchronized sensor acquisition in motor control applications using XAM3358ZCE.
Is hardware cryptographic acceleration available on the XAM3358ZCE?
Yes, the XAM3358ZCE includes dedicated hardware accelerators for AES-128/192/256, SHA-1/256, and random number generation (RNG). These modules operate independently of the ARM core and are accessible via TI's Cryptographic Services Library (CSL), enabling secure boot, encrypted firmware updates, and TLS offload without CPU overhead - a key capability confirmed in the AM335x security feature list.
